Photosensitive WS2/ZnO Nano-Heterostructure-Based Electrocatalysts for Hydrogen Evolution Reaction

“…Besides this, the synthesis of nanocomposites, nano-heterostructure, or nanohybrids has been proven to be more promising in the current scenario because of significant improvement in the HER activity by the highly controlled synthesis of catalysts with the desired proportion of materials and without disturbing the structural properties of host materials. , The use of various materials in the synthesis of nanocomposites, including nanostructures of transition-metal oxide (TMO) and noble metals, has shown enormous development in order to find the suitable catalyst with a low overpotential and high hydrogen yield. ,, Particularly, nanocomposites based on TMDCs, TMs, and TMOs have also emerged as high-performance catalysts ,, because of the simple and cost-effective synthesis and low hazard. Because of their controlled morphologies and atomically smaller size, they offer great catalytic activity even for their small amounts. ,, Additionally, the TMO/TMDC heterostructures/composites or TM/TMDCs heterostructures have shown great promise in the field of optoelectronics and self-driven photodetectors because of the formation of the type-II junction at the interface. − High-performance devices can be fabricated using these heterostructures as they show high and stable photo-absorption over a broad range of the solar spectrum from ultraviolet to near infrared. − These important optoelectronic ingredients of heterostructures can be utilized for the efficient photocatalysis. , Even, organic–inorganic nano-heterostructures can show a promising photoresponse owing to strong interface formation, which can be tuned by the proportion of constituents. − …”
