Researchers have developed Ru-CoFe-LDH nanosheets to enhance the efficiency of BiVO4 photoanodes for solar water splitting, achieving a photocurrent density of 4.51 mA/cm²—3.1 times greater than bare BiVO4. The incorporation of Ru sites improved charge separation and lowered the onset potential for water oxidation, while stability tests showed 81% performance retention after 30 minutes. DFT calculations indicated that Ru modifies charge distribution, facilitating oxygen evolution reactions.
