The doping of B in ZnO/CdS for enhanced visible-light H₂ production

Abstract

The visible-light water splitting enhancement of B in ZnO@CdS was systematically studied and the B doped ZnO@CdS rods (B-ZnO@CdS) showed an excellent H2 generation rate of 13.1 mmol h-1g-1, mostly...

Metal–organic framework-derived porous carbon-mediated ZnO–nano-ZnO core–shell structure with excellent photocatalytic activity

“…3c, and the three peaks of nZnO@PC at 531.8, 530.9, and 530.3 eV are indexed to adsorbed oxygen, oxygen vacancy, and lattice oxygen, respectively. 53 Oxygen vacancy is beneficial for the adsorption of oxygen, which is a positive condition for the formation of ˙O 2 − . It is well known that ˙O 2 − is the main active substance for photocatalytic degradation.…”

Review of Recent Developments in the Fabrication of ZnO/CdS Heterostructure Photocatalysts for Degradation of Organic Pollutants and Hydrogen Production

“…This is because the wide bandgap semiconductors have a limited visible-light absorption capacity and rapid recombination of charge carriers, whereas the narrow bandgap semiconductors still suffer from instability. Several methods, including the doping of metal ions and the development of binary or ternary composites, have been employed to overcome these drawbacks [34,35]. Among these techniques, constructions of heterostructures with a wide bandgap and a narrow bandgap semiconductor have been recognized as one of the most effective ways for enhanced visible-light-driven photocatalysis [36].…”
