Dihydrogen holds great promise as an alternative energy carrier in the near future. Water electrolysis has been considered to be one of the main routes to produce dihydrogen without fossil fuels. There are several hurdles to be overcome, one of which is the use of platinum (Pt) as an electrocatalyst. Extensive effort has been devoted to replacing Pt catalyst with earth-abundant materials in recent years. In this work, cobalt disulfide on carbon fiber paper (CFP) is prepared and evaluated as an alternative electrocatalyst. Our study reveals that cobalt disulfide and CFP work together to provide a high catalytic activity for hydrogen evolution reaction. In-depth characterization combined with electrochemical study provide new insights into this interesting synergistic effect, which is attributed to a gradual activation by defects on carbon surface.
