Abstract
CNT/VS2-MoS2 with a multi-interface structure shows significantly enhanced catalytic activity compared with MoS2, CNT/MoS2, CNT/VS2 and VS2-MoS2, including a low overpotential of -215 mV at 10 mA cm-2 and a small Tafel slope of 64 mV dec-1. The enhanced catalytic activity could be ascribed to the multiple interfaces in CNT/VS2-MoS2, 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.
