Microwave synthesized dry leaf-like mesoporous MoSe2 nanostructure as an efficient catalyst for enhanced hydrogen evolution and supercapacitor applications1

A uniform dry leaf-like mesoporous MoSe2 nanostructure was successfully synthesized via a microwave-assisted method. The MoSe2 nanostructure was optimized by maintaining the microwave reaction at 160 degrees C for 25 min. The mesoporous nanostructured MoSe2 was employed as an electrocatalyst for hydrogen evolution from water splitting. The MoSe2 with the novel mesoporous nanostructure led to a superior hydrogen evolution reaction with a small Tafel incline of 58 mV dec(-1) and remarkable long-term durability. The leaf-like mesoporous MoSe2 electrode achieved a capacitance of 257.38 F g(-1) at 1 A g(-1) with remarkable cyclic stability for 5000 cycles.
