Photoirradiation-Induced Exposure of Active Sites on Co <sub>3</sub> (Si <sub>2</sub> O <sub>5</sub> ) <sub>2</sub> (OH) <sub>2</sub> Nanosheets for Enhanced Electrocatalytic Oxygen Evolution Reaction
. Theoretical calculations further reveal that photoirradiation modulates the electronic structure of Co sites, shifting the d-band center closer to the Fermi level and thereby strengthening the adsorption of OER intermediates while lowering the reaction energy barrier. The solar driven water splitting process achieves a high Faradaic efficiency of 93.83%, and the solar-to-hydrogen energy conversion efficiency is 4.66%. This work provides an effective strategy for designing inexpensive and stable OER electrocatalysts.
