Abstract

ABSTRACT: In this paper, we report on development of 3D macroporous MoS2 thin film on Mo foil (MoS2 /Mo) by hydrothermal treatment of Mo foil in the presence of thiourea as an integrated hydrogen evolution cathode. Under acidic condition, the MoS2 /Mo electrode exhibits good catalytic activity needing overpotentials of 168 and 215 mV to achieve current densities of 10 and 100 mA cm −2, respectively, and its activity is preserved for at least 17 h. Remarkably, it also performs well in both neutral and alkaline solutions.
