Summary: In this study, zinc indium sulfide coupled polyaniline (ZnIn2S4/PANI) nanocomposites were synthesized using a chemisorption method. The nanocomposites exhibited significant enhancement in photo-catalytic and photoelectrochemical (PEC) water splitting activity under visible light illumination. The improvement in photodegradation and PEC water splitting activity is attributed to extended visible light absorption, synergistic effect of PANI, and the formation of a type-II heterojunction, which facilitates charge separation and faster transfer efficiency of photogenerated charge carriers.

Summary: Hexagonal zinc indium sulfide coupled g-C3N4 (H-ZnIn2S4/g-C3N4) nanocomposites were synthesized via chemisorption method, and their photoelectrochemical water splitting activity was investigated. The H-ZnIn2S4/g-C3N4 nanocomposites exhibited a 1.9 times higher photoelectrochemical performance than H-ZnIn2S4. The improved performance can be attributed to the formation of a type-II heterojunction, which enhances the separation and transfer of photogenerated charge carriers.

Summary: This study reports the rational design of a ZnIn2S4-based noble-metal-free photocatalyst for splitting water into H-2 and O-2, achieving promising photocatalytic activity through the precise control of NiCo2S4 structure and the controllable preparation of hierarchical heterostructure. The directional charge separation in ZnIn2S4 modified with separated dual cocatalysts effectively enhances the performance of the photocatalyst, surpassing most similar sulfide-based photocatalysts.

Summary: In this study, ZnIn2S4 nanosheet arrays (NSAs) were synthesized and sulfur vacancies were introduced on the surface through plasma treatment. The enhanced photoelectrochemical (PEC) performance of ZnIn2S4, including increased photocurrent and H-2 evolution rate, was attributed to improved visible light absorption and carrier separation, as well as the trapping effect of the sulfur vacancies. This work presents a novel strategy for enhancing the PEC hydrogen evolution of ZnIn2S4.

Summary: In this study, a sea urchin-like bimetallic NiCo2O4-decorated ZnIn2S4 heterojunction was fabricated to enhance the photocatalytic water splitting for H-2 production. The introduction of NiCo2O4 expanded the UV-vis absorption range, promoted charge separation, and decreased the charge transfer resistance, resulting in a faster H-2 evolution rate. The NiCo2O4/ZnIn2S4 composite also exhibited excellent stability during 5 consecutive cycles.

Summary: The effects of different band alignments in semiconducting heteronanosheets (HNSs) on photocatalytic water splitting were investigated. The results showed that ZnSe-based HNSs exhibited higher photocatalytic activity compared to ZnS-based HNSs, due to the S-scheme mechanism formed by internal electric field rather than the defect trapping-mediated transfer mechanism. Moreover, the long-lived carrier separation and efficient charge transfer pathways of ZnSe-based HNSs contributed to their superior photocatalytic performance.

Summary: Interface engineering in hybrid plasmonic metal/semiconductor heterostructures is an efficient approach to enhance the catalytic performance of photocatalysts and photoelectrochemical cells in harvesting and converting sunlight. The injection and utilization of hot electrons are achieved by fabricating a Au@ZnIn2S4/Ti3C2 system with well-defined interfaces. The core-shell Au@ZIS nanoparticles anchored on the 2D Ti3C2 surface optimize the electron transfer pathway and greatly promote the extraction of hot electrons. Furthermore, the efficient separation and transfer of electrons through a two-step transfer process result in a drastic improvement in the activities of photoelectrochemical seawater splitting, demonstrating the potential of this system for enhancing PEC performance.

Summary: A hierarchical Bi2WO6/BiFeWO6 architecture with enhanced photocatalytic performance for water splitting and H-2 generation was synthesized by developing n-n heterojunction between Bi2WO6 and BiFeWO6. The heterojunction showed high catalytic activity, good cycling stability and superior photoelectrochemical response due to the synergistic effect of high surface area, lower recombination rate, and suitable band edge potentials.
