Summary: A highly efficient and low-cost trifunctional electrocatalyst, FeNiP-NPHC, was fabricated via a hydrothermal-pyrolysis-phosphidation procedure. The FeNiP-NPHC showed superior performance in ORR, HzOR, and HER in alkaline seawater, benefiting from the strong coupling effect among FeP, FeNi2P, and N, P co-doped carbon, as well as the unique hierarchical structure. Density functional theory functions indicated that the three-phase heterojunction interface of FeNiP-NPHC effectively adjusted the d-band center and electronic structure, contributing to the optimized electrocatalytic performance. The concept of using FeNiP-NPHC as a trifunctional electrocatalyst was successfully demonstrated in the self-assembled DHzFC for OHzS in alkaline seawater.

Summary: Replacing the sluggish oxygen evolution reaction (OER) with the hydrazine oxidation reaction (HzOR) is an efficient approach to increase hydrogen production efficiency through water electrolysis. NiOOH@cobalt copper carbonate hydroxide nanorods demonstrate enhanced electrocatalytic activities toward the OER and HzOR. By using hydrazine in an alkaline electrolyte, a low cell voltage is required to achieve efficient hydrogen production with NiOOH@CoCu CH as both the anode and cathode.
