Abstract

Abstract : Porous nanosheets of Cu3 P@N, P co-doped carbon hosted on copper foam (Cu3 P@NPC-CF) exhibits excellent HER activity and ultrahigh stability in all pH solutions. Abstract : Hydrogen Evolution Reaction (HER) catalysts typically display poor physical stability which limits their performance and commercial use. Herein we have designed and fabricated a highly robust and cost-efficient catalyst which displays excellent activity and ultrahigh stability under a variety of conditions. This is accomplished by growing porous nanosheets of a N, P co-doped carbon shell (∼4 nm) wrapped in Cu3 P on current-collector copper foam (Cu3 P@NPC-CF). The prepared self-supported Cu3 P@NPC-CF catalyst delivers pH-universal HER electrocatalytic activity with excellent overpotentials of 81.94, 192.52 and 135.45 mV at 10 mA cm −2 in 0.5 M H2 SO4, 1 M PBS and 1 M KOH, respectively. Moreover, Cu3 P@NPC-CF possesses ultrahigh stability with current retentions of 81.32%, 96.06% and 95.61% after 90 h of chronoamperometry (CA) tests in acidic, neutral and alkaline solutions, respectively. The self-supported Cu3 P@NPC-CF electrocatalyst exhibits excellent HER activity and ultrahigh stability in all pH solutions yet was synthesized via a facile approach. This Cu3 P@NPC-CF catalyst provides a new reference for the development of HER electrocatalysts.
