B-SrTiO₃ was obtained by B-doping SrTiO₃ using the solid-phase synthesis method, followed by loading Rh, Cr, and Co co-catalysts (RCC) to produce the photocatalyst B-SrTiO₃-RCC. The prepared catalyst achieved complete over-all water splitting under 375 nm illumination with an apparent quantum efficiency (AQE) of 82.06%. The hydrogen production rate reached 4.92 mmol·g^-1·h^-1 with excellent stability in a long-term cycle test for approximately 600 h. B-doping induced the structural change of SrTiO₃ crystal from regular cube to truncated octahedron, leading to formation of more surface hydroxyl groups due to B-doping in Ti³⁺ defects, promoting the effective separation and transfer of photogenerated carriers, and thereby effectively enhancing the photocatalytic water splitting activity.
