Abstract Utilizing polymeric catalysts to generate hydrogen peroxide (H 2 O ) via photocatalysis for various industrial applications is a promising avenue, but the application potential constrained by their low charge separation efficiency and capacity oxygen adsorption activation. Herein, catalyst (NiRF) modified with Ni metal sites on resorcinol‐formaldehyde (RF) resin presented, which can efficiently produce H through in pure water. The optimal NiRF‐5 exhibits an impressive generation rate of up 31.75 m g −1 h under visible light irradiation, significantly outperforming most reported date. Experimental results coupled theoretical calculations simulation, indicate that incorporation nickel ions modulates band structure NiRF provides active conducive transformation oxygen. regulate ensure suitable configuration energy. This work novel design concept RF‐based photocatalysts offers approach development methods efficient photocatalytic production .
