The in situ construction of ZnIn₂S₄/CdIn₂S₄ 2D/3D nano hetero-structure for an enhanced visible-light-driven hydrogen production

Abstract

Through in-situ modification of CdIn2S4 nano-octahedron on the surface of ZnIn2S4 nanosheets, ZnIn2S4/CdIn2S4 nano-composites with tight interface contact are obtained by one-step solvothermal method. Due to ZnIn2S4/CdIn2S4 nano-heterostructure, the optimized...

One‐Step MOF‐Templated Strategy to Fabrication of Ce‐Doped ZnIn2S4 Tetrakaidecahedron Hollow Nanocages as an Efficient Photocatalyst for Hydrogen Evolution

“…[ 22 , 23 , 24 ] In addition, ultrathin 2D nanosheet structures of ZIS not only possess a high specific surface area but also shorten the diffusion distance of charge carriers to the abundance of exposed active sites. [ 25 ] However, the excessive self‐assembly and aggregation of 2D ultrathin ZIS nanosheets greatly reduce its number of active sites and block photogenerated carrier separation, which severely restricts its photocatalytic activity. [ 26 ] In general, pristine ZIS weakly adsorbs visible light; thus, it has a narrow solar light response range and poor charge separation/transfer efficiency.…”

Self-assembled transition metal chalcogenides@CoAl-LDH 2D/2D heterostructures with enhanced photoactivity for hydrogen evolution

“…), which possess desirable characteristics, such as adjustable direct band gap and wide optical absorption range, representing a family of visible light-responsive photocatalysts with promising performances for H 2 evolution. 8–12 On the other hand, their photocatalytic activity is limited by the high bulk recombination of photogenerated charge carriers and the deficiency of active sites. In this regard, the state-of-the-art approach to boost the photocatalytic performance is constructing TMC-based hybrid photocatalyst systems.…”

Fast Interlayer Charge Separation and Transmission in ZnIn2S4/CNTs/ZnS Heterojunctions for Efficient Photocatalytic Hydrogen Evolution

“…As a popular II–III 2 –VI 4 ternary chalcogenide semiconductor, because of adjustable shape, strong light absorption, suitable bandgap and excellent chemical stability, ZnIn 2 S 4 (ZIS) has attracted much attention in the field of photocatalytic hydrogen evolution [12] . The photocatalytic hydrogen evolution of bare ZIS, however, has a low H 2 conversion efficiency due to a paucity of catalytic active sites and the carriers′ high recombination efficiency [13–15] . As a result, several attempts have been undertaken to improve the photocatalytic hydrogen evolution of ZIS in order to improve carrier usage efficiency and prevent charge recombination.…”
