Construction of a unique 2D/0D NiO/ZnCdS p–n hetero junction photocatalyst with highly improved photocatalytic H2 generation capacity

“…3,[13][14][15] Nevertheless, ZnCdS still suffers from rapid charge recombination and sluggish kinetics for H 2 generation. 16,17 Until now, numerous ZnCdS-based heterojunction photocatalysts, such as MXene/Zn x Cd 1Àx S Schottky heterojunctions, 18,19 Z-scheme a-Fe 2 O 3 /Zn 0.4 Cd 0.6 S, 20 p-n NiCo 2 O 4 / Zn 0.1 Cd 0.9 S, 21 type-I Zn 0.5 Cd 0.5 S/ZnS(en) 0.5 , 22 and type-II onion-like carbon/Zn 0.5 Cd 0.5 S, 23 have been developed to achieve enhanced photocatalytic performance. Among these, p-n heterojunctions can promote photogenerated electron-hole pair separation owing to the internal electric field formed at the heterointerface, which favors photocatalytic activities.…”

Porous Zn1–xCdxSe/ZnO Nanorod Photoanode Fabricated from ZnO Building Blocks Grown on Zn Foil for Photoelectrochemical Solar Hydrogen Production

“…14 Consequently, a novel class of inorganic−organic hybrid materials formed by fusing an organic component with an inorganic building block has attracted considerable interest. 15,16 An innovative organic−inorganic hybrid material shows a significant quantum confinement effect with a precise periodic arrangement but suffers from poor PEC properties due to a wide bandgap. 15 Despite this, organic−inorganic hybrid materials act as mother materials for the development of porous materials via simple ion exchange using powder and electrode systems.…”

“…Therefore, coupling of metal oxide with other narrow bandgap chalcogenide semiconductors (CdS, CdSe, and CdTe) could enhance charge generation, reduce the recombination rate, and improve the PEC hydrogen production performance. − Among them, CdSe has received the most attention in the past years due to its narrow bandgap (1.8 eV) and excellent PEC photocurrent density. , However, conventional metal chalcogenides are more difficult to manage in terms of geometrical size and shape than organic compounds . Consequently, a novel class of inorganic–organic hybrid materials formed by fusing an organic component with an inorganic building block has attracted considerable interest. , An innovative organic–inorganic hybrid material shows a significant quantum confinement effect with a precise periodic arrangement but suffers from poor PEC properties due to a wide bandgap .
