Synthesis of transition metal sulfide nanostructures for water splitting

Transition metal sulfides are inexpensive, earth abundant, and environmentally friendly materials. They have been extensively studied for fundamental and applied research for numerous applications, particularly for energy applications, for example, photovoltaics, batteries, supercapacitors, and fuel cells. Nanoarchitectures are the trending form of transition metal sulfides for efficient energy conversion applications. This chapter presents the catalytic performance of transition metal sulfide nanostructures for water splitting by focusing on the current status of synthesis protocols. From this viewpoint, we outline the future perspectives of transition metal sulfide nanostructures with the approaches to improve the stability of transition metal sulfides-based photoelectrodes for water splitting.
