The surface engineering of ReS2 with cobalt for efficient performance in hydrogen evolution under both acid and alkaline conditions†
Abstract
Cobalt-modified rhenium disulfide nanosheets rich in defects, obtained by following an ingenious atom substitution strategy, exhibited boosted HER performance. The 2%-Co doped ReS2 sample was highly efficient in both acid electrolyte (149 mV) and alkaline electrolyte (240 mV), achieving a current density of 10 mA cm−2 as well as superior long-term durability.
