Metal nanoparticles have always attracted attention for applied catalysis in technical fields including sensorapplications. Biogenically synthesized nanoparticles are uniquely non-toxic and possess enhancedantimicrobial activity. Eco-friendly palladium nanoparticles (PdNPs) synthesized from plant extractsand/or biopolymers have wide biomedical, environmental, and biosensor applications. The size, shape,stability, and catalytic behavior of PdNPs are influenced by factors such as pH, temperature, concentrationof metallic salt, and concentration of plant extract/biopolymer solutions. This review article focuseson the comprehensive synthesis of biogenic PdNPs from phytochemicals/biopolymers and conciselyreports their heterogeneous organic catalytic applications. Furthermore, improved catalytic efficiencies,selectivities, and reaction yields of organic coupling reactions catalyzed by biogenic PdNPs are discussedin detail. This review highlights the safety, sustainability, and effective catalytic activity of biogenicPdNPs for organic coupling reactions, which ensures lesser toxic waste generation and reduces hazardouseffects on the environment.

In the present work, a novel method for the green synthesis of CeAlO3 (CAO) polycrystalline powderthrough deep eutectic solvents (DES) was carried out by hydrothermal method. The carbon nitride(CN) was synthesized directly by fractional thermal polymerisation process. The combination ofCeAlO3 with CN provides an excellent sensing platform for developing highly sensitive and stable electrocatalystfor non-enzymatic glucose (GLU) oxidation. The structural, morphological and electrochemicalanalysis of CeAlO3/CN (CAO/CN) shows the successful synthesis without any impurities. The synergisticeffects of pyridinic-N, pyrrolic-N and graphitic-N are highly influencing and playing a prominent role insensory performances of the prepared CAO/CN nano-electrocatalyst towards GLU sensing. The limit ofdetection (LOD) at CAO/CN modified glassy carbon electrode (CAO/CN/GCE) was calculated to be0.86 nM in the linear concentration range of 0.01–1034.5 mM by amperometric method. The antiinterference,reproducibility, repeatability and stability analysis suggest the promising performance ofthe fabricated electrode towards GLU detection. The real time application of CAO/CN/GCE was evaluatedtowards GLU sensing in human blood, saliva and sweat, a satisfactory result was obtained. Therefore, theCAO/CN/GCE has a great application prospect as a highly efficient catalyst material for highly sensitiveand efficient non-enzymatic glucose sensor.
