Abstract:Developing efficient electrocatalysts to achieve sustainable hydrogen production from electrocatalytic water splitting remains a task of great significance and challenges. Atomic doping is of importance to enhance the performance of electrocatalysts by modulating the local microenvironmental of the designed nanomaterials. Herein, we have developed a porous CoP electrocatalyst with Ru and B atoms co-doping (Ru/B-CoP). Benefiting from the atomic doping and the unique multivacancy nanosheet structure, only 39 mV, 52 mV, and 87 mV are required to achieve 10 mA cm-2 for HER in 0.5 M H2SO4, 1 M KOH, and 1 M PBS, respectively, and also achieves excellent performance in seawater. It is shown that the introduction of Ru, B in CoP can successfully regulate the electronic structure of the samples and can provide enormous potential in the field of sustainable energy storage and conversion.
