Prussian-Blue-Analogue-Derived Ultrathin CoP-FeP Nanosheets for Universal-pH Overall Water Splitting.

The great interest in large-scale electrochemical water splitting toward clean hydrogen has spurred large numbers of studies on developing cost-efficient and high-performance bifunctional electrocatalysts. Here, a Prussian-blue-analogue-derived method is proposed to prepare honeycomb-like ultrathin and heterogeneous CoP-FeP nanosheets on nickel foam, showing low overpotentials of 0.080, 0.
