Bifunctional electrocatalysts for overall water splitting (OWS) is critical for sustainable hydrogen production but remains challenging due to the sluggish kinetics and leaching of metal ions. Herein, we present a kind of phosphorus and molybdenum codoped ruthenium and ruthenium oxides heterostructure (P,Mo0.1-Ru/RuO2) as a highly efficient bifunctional electrocatalyst for alkaline OWS. The incorporation of P facilitates the electron transfer from P to Ru, leading to the partial reduction of RuO2 to metallic Ru. Moreover, the reduced oxidation of Ru suppresses the dissolution of RuO2, favoring the structural stability. In alkaline media, P,Mo0.1-Ru/RuO2 demonstrates enhanced hydrogen evolution and oxygen evolution activities, requiring overpotentials of only 61 and 230 mV, respectively, to achieve a current density of 10 mA cm- 2. When employed as anode and cathode for OWS, the P,Mo0.1-Ru/RuO2 catalyst enabled a low cell voltage of 1.50 V at 10 mA cm- 2, along with an enhanced electrochemical stability. These results highlight the synergistic effect of anion and cation codoping in enhancing electrocatalytic performance, offering a promising strategy for the design of advanced bifunctional catalysts for sustainable hydrogen production.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
