Abstract:
The urgent global demand for sustainable green energy solutions has recognized hydrogen (H2) as a viable green energy carrier. This study explores the efficient production of H2 as a potential source of sustainable, environmentally friendly, high-energy-density fuel characterized by eco-friendly burning by-products. The research focuses on the photohydrolysis reaction of ammonia borane (AB), utilizing CdO-doped ZnO nanoparticles (NPs) embedded in polyurethane (PU) nanofibers (CdO/ZnO NPs@PU NFs) as a novel photocatalyst. Three different amounts of CdO/ZnO NPs were loaded onto PU NFs. The synthesized CdO/ZnO NPs@PU NFs exhibited good photocatalytic performance under visible light, producing approximately 67 mL of H2 from 1 mmol of AB in 15 min with the sample containing the highest loading of CdO/ZnO NPs@PU NFs. This impressive photocatalytic performance is attributed to the synergistic effects of CdO and ZnO, which enhance charge carrier separation and broaden bandgap absorption in the visible spectrum. Kinetic studies demonstrated that the reaction exhibited first-order kinetics regarding catalyst dosing and zero-order kinetics concerning AB concentration, with an activation energy (Ea) of 32.28 kJ/mol. The results position CdO/ZnO NPs@PU NFs as effective photocatalysts for H2 photogeneration under visible light irradiation.

The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
