Tuning the Electrocatalytic Activity of MoS2 Nanosheets for Hydrogen Evolution Reaction via Cobalt-Embedded Nitrogen-Rich Graphene Networks
Source abstract
Abstract
MoS2 nanosheets were hybridization with a cobalt-embedded nitrogen-rich graphene networks (Co@N-GNWs) to tune the electrochemical hydrogen evolution activity. Experimental observation and theoretical calculation have proven that the energy level of MoS2 can be engineered to match the redox pair H+/H2 in water splitting, thus showing enhanced overall performance. The as-obtained catalyst demonstrates high catalytic activity with a small overpotential of 165 mV at 10 mA cm–2, a Tafel slope of 50 mV decade–1, and good stability. The coupling of MoS2 with this specific substrate to tune its catalytic activity paves a way to boost the electrocatalytic activity of similar catalysts.
