Transition metal selenides and diselenides: Hydrothermal fabrication, investigation of morphology, particle size and and their applications in photocatalyst

This review investigates hydrothermal synthesis of metal selenides and diselenides. Briefly, structures, applications and formation mechanisms are studied. The strategies for developing metal selenides, including NiSe, NiSe2, Ni3Se2, CdSe, FeSe2, MnSe2, CoSe, CuSe, Cu1.8Se, CuSe2, Cu3Se2 and ZnSe are discussed. More of 50 hydrothermal methods used for the synthesis of metal selenides are discussed. As well as the investigation of the photocatalytic activities of these metal selenides are followed by different synthesis methods and strategies employed for the synthesis of them.
