Abstract
Developing an outperformed bifunctional water splitting catalyst serving in both basic solutions and seawater is of great significance. Herein, we synthesized the binder-free copper mesh (CM)-based Pt-Cu<sub>3</sub>P/Cu<sub>3</sub>(PO<sub>4</sub>)<sub>2</sub> through two-step reaction courses. The achieved Pt-Cu<sub>3</sub>P/Cu<sub>3</sub>(PO<sub>4</sub>)<sub>2</sub>/CM (abbreviated as Pt-Cu<sub>3</sub>P/CPO/CM) has the appearance of nanosheets decorated with uniformly distributed nanoclusters. Electrochemical testing results confirm its Pt/C/CM-like hydrogen evolution reaction (HER) behavior and superior to RuO<sub>2</sub>/CM oxygen evolution reaction (OER) activity. In addition, to deliver a 10 mA cm<sup>-2</sup> current density, the acquired voltage of Pt-Cu<sub>3</sub>P/CPO/CM is only 1.653 V in basic solutions and 1.676 V in seawater, even lower than the Pt/C/CM-RuO<sub>2</sub>/CM electrode pair (1.668 V) in the basic solutions. Further insight analysis certifies that the in situ-formed Pt-Cu<sub>3</sub>P/CPO heterojunction, together with the enlarged electrochemical surface-active area and the shortened charge transfer resistance, hugely improved the electrocatalytic property of Pt-Cu<sub>3</sub>P/CPO/CM. This work not only obtains an excellent self-supported bifunctional catalyst but also provides a material design idea to other Cu<sub>3</sub>(PO<sub>4</sub>)<sub>2</sub>-based catalysts.
