Low-temperature phosphidation synthesis of flower-like Ru-CoVO-P polymetallic catalyst for enhanced overall water splitting in alkaline seawater.

ABSTRACT: Developing efficient and stable bifunctional electrocatalysts for overall water splitting, especially in practical electrolytes such as seawater, remains a significant challenge in the field of energy conversion. Herein, we report the successful synthesis of a three-dimensional, flower-like polymetallic phosphide electrocatalyst (Ru-CoVO-P), constructed from self-assembled ultrathin nanosheets, via a facile hydrothermal method combined with a low-temperature phosphidation strategy. The catalyst exhibits excellent bifunctional activity in 1 M KOH, requiring overpotentials of only 88.7 mV (HER) and 248.3 mV (OER) to achieve 10 mA cm^-2. After 240 hours of cycling in a two-electrode system, a cell voltage of only 1.753 V is required to achieve a current density of 50 mA cm
