Abstract Transition metal chalcogenides (TMCs) are widely used in photocatalytic fields such as hydrogen evolution, nitrogen fixation, and pollutant degradation due to their suitable bandgaps, tunable electronic optical properties, strong reducing ability. The unique 2D malleability structure provides a pre‐designed platform for customizable structures. introduction of vacancy engineering makes up the shortcomings photocorrosion limited light response greatest support TMCs terms kinetics thermodynamics photocatalysis. This work reviews effect on performance based semiconductor TMCs. characteristics strategies summarized, development photocatalysis materials energy conversion, degradation, biological applications is reviewed. contribution vacancies range charge transfer also discussed from perspective manipulation. Vacancy not only controls optimizes TMCs, but improves transfer, surface properties. synergies between atomic doping, other vacancies, heterojunction composite techniques detail, followed by summary current trends potential expansion.

Hedgehog Zinc Oxide–Graphene Quantum Dot Heterostructures as Photocatalysts for Visible-Light-Driven Water Splitting

ACS Omega, Journal Year: 2024, Volume and Issue: 9(39), P. 40790 - 40800

Published: Sept. 16, 2024

The development of efficient photocatalysts for sustainable hydrogen production via water splitting is vital advancing renewable energy technologies. In this study, we present the synthesis and characterization a novel visible-light-active photocatalyst comprising hedgehog-shaped zinc oxide (ZnO) nanostructures coupled with graphene quantum dots (GQDs). Optical properties assessed by UV-visible photoluminescence (PL) spectroscopy revealed that ZnO/GQDs heterostructure possessed reduced band gap (2.86 eV) compared pristine ZnO (3.10 eV), resulting in improved light absorption charge separation. Electrochemical analyses indicated significantly higher photocurrent response lower transfer resistance nanostructure. Photocatalytic tests demonstrated achieved over 3-fold (H
