摘要

The development of low-cost and high-efficiency non-noble metal cocatalysts is one of the important factors in promoting the separation of photogenerated carriers. In this study, we report a stable and highly active MoC@NC/ZnIn2S4 heterostructure for photocatalytic H2 evolution under visible light. The optimized MoC@NC/ZnIn2S4 composite displays an excellent photocatalytic H2 evolution rate of 45.4 μmol h−1, which was 8.3 times higher than that of ZnIn2S4. Its apparent quantum efficiency reached 51.5% at 420 nm. Moreover, the photocatalyst exhibits excellent stability and recycling capabilities. This remarkable activity can be ascribed to the modification of MoC@NC onto the ZnIn2S4 surface by forming an intimate contact interface, which can suppress the recombination of photogenerated carriers, consequently leading to superior photocatalytic H2 evolution performance. This study indicated that MoC@NC can act as an outstanding cocatalyst for promoting ZnIn2S4 photocatalytic performance.

CrystEngComm is the forum for the design and understanding of crystalline materials. We welcome studies on the investigation of molecular behaviour within crystals, control of nucleation and crystal growth, engineering of crystal structures, and construction of crystalline materials with tuneable properties and functions. We publish hypothesis-driven research into… how crystal design affects thermodynamics, phase transitional behaviours, polymorphism, morphology control, solid state reactivity (crystal-crystal solution-crystal, and gas-crystal reactions), optoelectronics, ferroelectric materials, non-linear optics, molecular and bulk magnetism, conductivity and quantum computing, catalysis, absorption and desorption, and mechanical properties. Using Techniques and methods including… Single crystal and powder X-ray, electron, and neutron diffraction, solid-state spectroscopy, spectrometry, and microscopy, modelling and data mining, and empirical, semi-empirical and ab-initio theoretical evaluations. On crystalline and solid-state materials. We particularly welcome work on MOFs, coordination polymers, nanocrystals, host-guest and multi-component molecular materials. We also accept work on peptides and liquid crystals. All papers should involve the use or development of a design or optimisation strategy. Routine structural reports or crystal morphology descriptions, even when combined with an analysis of properties or potential applications, are generally considered to be outside the scope of the journal and are unlikely to be accepted.
