Abstract

CNT/VS-MoS with a multi-interface structure shows significantly enhanced catalytic activity compared with MoS, CNT/MoS, CNT/VS and VS-MoS, including a low overpotential of -215 mV at 10 mA cm and a small Tafel slope of 64 mV dec. The enhanced catalytic activity could be ascribed to the multiple interfaces in CNT/VS-MoS, which can promote charge transfer and yield abundant active sites. This study provides a valuable route to improve the catalytic performance of two-dimensional electrocatalysts.
