<P><B>Abstract</B></P> <P>A novel and powerful chemiluminescence (CL) system was developed based on the promoting effect of graphene quantum dots (GQDs)/bisulfite on rhodamine B (RB)-H<SUB>2</SUB>O<SUB>2</SUB> CL reaction. GQDs were synthesized by a simple, green and affordable approach and characterized using their distinctive absorption and emission patterns. X-ray diffraction (XRD), Fourier transform infrared (FT-IR) transmission and transmission electron microscopy (TEM) analysis were implemented for complementary studies on the structural and morphological characteristics of GQDs. The simultaneous enhancing effect of the synthesized GQDs and bisulfite on the CL emission of RB-H<SUB>2</SUB>O<SUB>2</SUB> reaction provided a more strong and efficient CL system. The mechanism of CL emission was described. Furthermore, HCHO as a well-known pollutant, could selectively diminish the developed CL system. This effect was linearly proportional to HCHO concentration which turned the introduced CL system to a susceptible chemosensor for HCHO. Under the optimized operational condition, the linear changing of CL response was obtained in HCHO concentration ranges of 0.02–5μgL<SUP>−1</SUP> and 5–11μgL<SUP>−1</SUP>, with limit of detection (LOD) and quantification (LOQ) of 6ngL<SUP>−1</SUP> and 20ngL<SUP>−1</SUP>, respectively. Ultimately, presented CL chemosensor was served as an accurate tool for determination of formaldehyde concentration in water and wastewater samples.</P> <P><B>Highlights</B></P> <P> <UL> <LI> GQDs and bisulfite can simultaneously enhance the CL emission of RB-H<SUB>2</SUB>O<SUB>2</SUB> reaction. </LI> <LI> RB-H<SUB>2</SUB>O<SUB>2</SUB>-GQDs-SDS-bisulfite system provides a strong and beneficial CL emission. </LI> <LI> HCHO can selectively diminish the emission of developed CL system. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

To well describe the photoassisted-electrochemical process for treatment of the contaminated water, a new kinetic model was established based on the intrinsic reactions of the process. The kinetic model correlated apparent kinetic constants to operational parameters including applied current, initial dye concentration and flow rate. Degradation experiments were carried out with boron-doped diamond (BDD) anode and carbon nanotubes–polytetrafluoroethylene (CNTs–PTFE) cathode. The proposed kinetic model was validated by the experiments of C.I. Acid Blue 92 degradation in aqueous solution. The goodness of fitting (R2 = 0.96) demonstrated that the new model could describe both the kinetics and the hydrodynamics of the photo-electrochemical system.

Treatment of C.I. Acid Red 17 (AR17) by heterogeneous photo-Fenton-like process was studied using calcined laterite soil as an iron source. A complete characterization was performed to explain some of the properties of the used catalyst. Comparing the processes of heterogeneous Fenton-like and photo- Fenton-like, revealed that using heterogeneous photo-Fenton-like led to the highest decolorization efficiency (94.71% at 120 min). Experimental results indicated that the heterogeneous photo-Fenton-like process could be explained in terms of the Langmuir–Hinshelwood kinetic model. The main roles of hydroxyl radicals in degradation process were investigated by adding of various radical scavengers

Undoped and Gd-doped PbSe nanoparticles were synthesized through a simple hydrothermal method. The photocatalytic activity of the catalysts was evaluated through the degradation of sulfasalazine (SSZ)under visible light irradiation. Synthesized nanoparticles were characterized by SEM, XRD, and XPStechniques. The photocatalytic degradation efficiency of SSZ in the presence of 8% Gd-doped PbSe(80.67%) was higher than that of undoped PbSe (42%). The order of the inhibitory effect of differentinorganic ions was HCO3> Cl > SO42 > F . The photocatalytic degradation intermediates wereidentified using GC–MS. Phytotoxicity of SSZ and its intermediates formed in photocatalytic processwere evaluated.

Herein, Fe3O4 nanospheres attached on N, S co-doped graphene quantum dots (NSG) enclosed CdSenanoparticles (CdSe/NSG–Fe3O4) is introduced as a magnetic high-performance photocatalyst for theheterogeneous photodegradation of methylene blue in aqueous solutions. The as-prepared CdSe/NSG–Fe3O4 nanocatalyst showed high stability and adequate ferromagnetism which makes it easy to beseparated and reused. CdSe/NSG–Fe3O4 nanocomposites displayed enhanced photocatalytic activity forthe degradation of organic compounds such as azo-dyes compared with CdSe nanoparticles. In view ofthese advantages offered by the prepared nanocatalyst, it has a high potential for the degradation oforganic contaminants.

Plasma-treated hematite (PTH) nanostructures were produced from natural hematite (NH) using N2plasma considering its cleaning and sputtering effects which lead to larger surface area. The NH and PTHwere characterized by XRD, FT-IR, SEM, EDX, XPS, and BET methods. The catalytic activity of the PTH inheterogeneous Fenton-like process was higher than the NH for degradation of Acid Red 17. The GC–Masstechnique was used to recognize some of the intermediates and a possible degradation pathway wasproposed. Environment-friendly preparation of the catalyst, insignificant leaked iron concentration andsuccessive usages at milder pH were the substantial advantages of the PTH.

The sonochemically synthesized Ho-doped ZnO nanoparticles were characterized by XRD, SEM, TEM,and XPS techniques. The sonocatalytic degradation of Reactive Orange 29 (RO29) was greater than thatwith sonolysis alone. DE% declines with the addition of chloride, carbonate, sulfate, and tert-butanol asradical scavengers. Addition of potassium periodate, peroxydisulfate, and hydrogen peroxide asenhancers improves DE%. The results demonstrate proper reusability of the doped sonocatalyst. Degradation intermediates were identified by gas chromatography–mass spectrometry (GC–MS). Usingnonlinear regression analysis, an empirical kinetic model was developed to predict the pseudo-first-order constants (kapp) as a function of the operational parameters.

Herein, air, argon, nitrogen and oxygen plasmas were used in glow discharge plasma under alternativecurrent to enhance the surface properties of graphite. The plasma-treated graphite electrodes (PTGE)were used as cathode in electro-Fenton (EF) for Acid Orange 7 (AO7) degradation. O2-PTGE exhibited thebest activity owing to its improved surface characteristics. Later, the effects of the main operationalcondition on O2-PTGE efficacy in EF and the stability of O2-PTGE were evaluated and degradationintermediates were identified. Finally, the performance of the studied system was assessed inheterogeneous condition using martite as catalyst and compared with homogeneous system.

Herein, novel Cu2O–CuO/HTC composites were prepared by hydrothermal precipitation employing ascarrier sawdust hydrochar carbonized at 200 C for 2, 6, and 12 h. The composites were used for theeffective sonocatalytic degradation of three dyes (Acid Blue 92 (AB 92), Acid Red 14 (AR 14) and AcidOrange 7 (AO 7)) with different molecular structure. To gain insight into the functional groups, crystallinestructure, elemental composition and optical characteristics of the Cu2O–CuO/HTC composites, FT-IR,XRD, EDX and UV–vis analyses were carried out. Also, the surface morphology and area of the Cu2O–CuO/HTC composites were investigated by SEM and BET analysis. The effect of different parameters, such asdye concentration, solution pH, and catalyst dosage on the sonodegradation process was examined. Among the as-prepared composites, the Cu2O–CuO/HTC-2 h sample exhibited the best performance,offering a degradation efficiency of 85.43% after 90 min. GC-MS analysis was in addition employed todetermine potential intermediates. To assess the mineralization of dye solution under optimumconditions, COD analysis was performed implying 77.77% removal efficiency. Additionally, the reusabilityand stability of the as-prepared composites were verified. The leaching copper concentration in theaqueous phase was measured within four consecutive runs.

Herein, a Z-scheme 2D/2D WO3@CoFe-LDH nanocomposite was synthesized and characterized by XRD,FT-IR, SEM, TEM, EDX, X-ray dot mapping, BET, PL, DRS, and XPS analysis. The integration of the sosynthesizedWO3@CoFe-LDH nanocomposite, ultrasonic, and ozone inferred the existence of a synergyfactor of 2.26 > 1 and 2.17 > 1 for the removal of Acid blue 9 and Acid Orange 7, respectively. Catalystdosage of 1 g/L, the solution pH of 8, the mixture dye concentration of 50 mg/L, and the ozoneflow rate of3 L/h were determined to be the optimum value for the extreme degradation of the dye mixtures under100 min of the sonocatalytic ozonation process. Additionally, the reusability experiments showed thatthe DE was above 80% after 5 times reuse of WO3@CoFe-LDH nanocomposite implying its retainedproperties during the sonocatalytic ozonation process. The contributed active radicals in the degradationof the dye mixtures were profoundly studied and reported to be mainly OH and O2. The so-generatedintermediates were recognized using GCMS analysis and a postulated degradation mechanism wasreported for each of the target pollutants in the presence of WO3@CoFe-LDH nanocomposite. The toxicitytests proved a nontoxic media after the sonocatalytic ozonation of the mixture dyes due to the successiveattack of the reactive oxygen species to the intermediates.
