Abstract

Amorphous MoS2 porous thin films (denoted as MoS2 PTFs) with high activity towards hydrogen evolution reaction (HER) were fabricated by in situ sulfuration of a Mo substrate. A small overpotential (∼120 mV) and a low Tafel slope (∼41 mV dec−1) can be observed and their excellent performance was ascribed to the combination of the amorphous feature, porous structure and optimized thickness.

Abstract

β-Ni(OH)2was constructed into a three-dimensional mesoporous film on Ni foam with ultra-thin (∼6 nm) primary nanowalls showing ultrahigh specific capacitance (2675 F g−1) and excellent cycling performance (>96% for 500 cycles). The capacitance was higher than theoretical value possibly due to the combination of Faradic and electrical double-layer capacitances. [ABSTRACT FROM AUTHOR]
