Silicate material prepared from high-alumina coal fly ash (HACFA) was characterized by using XRD, SEM, FTIR spectroscopy, TGA-DSC, and elemental analysis. These spectral results show that the silicate material is mainly composed of eight elements--O, C, Si, Ca, Na, Mg, Al, and Fe, which exist as the formations of Ca2+, Na+, Mg2+, Al3+, Fe3+, SiO3 2−, and CO3 2−, and some adsorbed water and crystal water are determined in the silicate material. The material with surface area of 117.12m2/g shows a faveolate structure, and a pore size distribution of silicate material is calculated at 11.01 nm from the nitrogen desorption isotherm using the BJH model. When the material was used for CO2 adsorption at T=323.15 K and flow rate=95mL/min with 15.79% (vol) CO2, a dynamic adsorption capacity of CO2 on the surface of silicate material was found at 8.67mg/g and the adsorption values decreased weakly after seventeen recycling times. The investigation of dynamic adsorption behavior shows that the silicate material presents similar adsorption properties with commercial active carbon and stronger adsorption properties than commercial diatomite.

<P><B>Abstract</B></P> <P>Folate receptor targeted photo-luminescent quantum carbon dots (Fr-CDs) were successfully prepared from folic acid and phenylenediamine isomers through hydrothermal approaches. Fr-CDs were spherical particles smaller than 10 nm, and emit stable green, blue and red luminescence under ultraviolet region excitation (λex = 365 nm) with maximum emissive lengths at 530, 429, and 612 nm. And the corresponding photoluminescence quantum yield as 15.4%, 12.6% and 16.2% respectively. Up-converted photoluminescent properties in near infrared 800 nm spectral region located in green, blue and yellow region. In-vitro studies showed Fr-CDs had almost none cytotoxicity (cell viability over 80%) and high affinitive to the Hela celline highly-expressed-folate-receptor membranes, and lighted on cytoplasm as the fluorescent marker. It displayed long luminescent-stability with PL intensity above 90% in ultraviolet illuminant exposure over 24 h. In in-vivo studies, Fr-CDs were internalized and accumulated in targeted cancer tissues of cervical carcinoma and the emitting fluorescence maintains over 30 min.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Multicolor carbon dots was prepared from folic acid and phenylenediamin isomers. </LI> <LI> These carbon dots exhibit targeting abilities with high affinity to ovarian cancer cells and tissues. </LI> <LI> Ultra-violet and near-infrared light excited photo-luminescent spectrums were investigated, and related quantum yield was calculated. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>FA-doped CDs can effectively target ovarian cancer cells and aggregate in ovarian tumor tissue in a short 15 min.</P> <P>[DISPLAY OMISSION]</P>

A highly stable silicate material from high-alumina coal fly ash was prepared and characterized using X-raydiffraction, scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, thermal analysis, Xrayphotoelectron spectroscopy, and elemental analysis. The spectral results show that the silicate material was mainlycomposed of six elements, C, Ca, O, Si, Mg, and Al, in the form of Ca2+, Mg2+, Al3+, SiO32−, and CO32− ions. Some adsorbedwater and/or water of crystallization was also observed. The silicate material showed exceptionally high capabilityto adsorb volatile organic compounds (VOCs). The results of dynamic adsorption behavior show that the silicatematerial presents similar properties with commercial activated carbon and stronger absorption properties than commercialdiatomite for the adsorption of VOCs. The FTIR spectral results show weak hydrogen bonding interactions ofthe silicate material with three VOCs.
