Unlocking the potential of CdS-based photocatalysts for high-efficiency hydrogen evolution in water splitting

CdS-based nanostructures have recently gained a lot of curiosity in photocatalyst study. Significant progress has been made in solar-fuel conversion and environmental refining in terms of CdS. This paper includes a detailed overview of the design strategies used for CdS-based nanostructured photocatalysts to increase the efficiency of H 2 evolution. Despite tremendous development in recent years, there are still various challenges, with an overall understanding of the process for improving H 2 reported. Various approaches were developed to improve the generation of photocatalytic H 2 using CdS-based nanostructures. These include multi-component solid solution development, cocatalyst doping, Z-scheme heterostructure construction, multifaceted nanostructure development, and photo-corrosion reduction. CdS photocatalysts with higher visible light absorption, redox capacity, and load separation efficiencies may be created. The longevity and homogeneity of photocatalysts remain key challenges that must be tackled in the long term. In brief, researching novel approaches for enhancing the general effectiveness and usefulness of CdS-based nanomaterials may open up new paths for the efficient use of solar energy to generate hydrogen fuel.
