Advancements in metal selenide nanocomposites for efficient photocatalytic water splitting applications

Abstract

Energy sustainability and cleanliness have given rise to profound exploration due to development of proficient photocatalytic materials,capable for water splitting, which is an all-important process for the production of hydrogen fuel renewable. Metal selenide nanocomposites with their special electrical and structural traits have been of growing interest to be used in photocatalytic water splitting processes. This paper highlights recent progress in the synthesis and application of metal selenide nanocomposites that result in improved performance of photo-electrolysis of water. Metal selenide nanocomposite can be manufactured nowadays by novel techniques, such as solvothermal, hydrothermal and chemical vapor deposition. It renders an electrons transfer in a longitudinal way and effectively applies its effects. As compared to the other conventional semiconductor materials mostly as nickel selenide (NiSe), cobalt selenide (CoSe) and iron selenide (FeSe) are renowned to show higher light materials. Metal selenides polymers have proved that they can bring the elevation of the water splitting systems’ efficiency, photocurr

ents, and hydrogen evolution rates. The synergistic effects of mixing components such as metal corrosion with other materials as heteroatom composed semiconductors or carbon nanomaterials become even more significant when they provide active sites for other atoms and facilitate charge transfer. The work is focused on deepening the understanding of basic ideas governing photocatalytic activity by conducting research to find innovative approaches which will provide answers to the most complicated problems yet to be resolved in the area of metal selenide nanocomposites. Hence, as long as scientists are going to investigate and improve those materials based on metal selenide nanocomposites, these can be seen as material to the progress of photocatalytic water splitting and taking the cause of creating sustainable and environmentally friendly energy resources.
