Abstract In the midst of global energy crisis, conversion solar into chemical or high‐value chemicals has become critical. Hydrogen peroxide (H 2 O ), a versatile oxidizing agent, plays an important role in synthesis, medical disinfection, and clean generation via fuel cells. Recently, photocatalytic H from water oxygen using covalent organic frameworks (COFs) metal–organic (MOFs) emerged as sustainable approach. this context, novel dimolybdenum paddlewheel‐embedded COF (Mo‐DHTA COF) is presented synthesized for generation. It observed that Mo sites help to bind molecule, while high‐energy valence band electrons localized on α‐hydroquinone moiety facilitate efficient photoelectron transfer reduction. Simultaneously, reduced electron density above hydroxy groups conduction serves proton source during production. Due these synergistic effects, Mo‐DHTA exhibited production rate 626 µmol g −1 h aqueous ethanol 4084 benzyl alcohol, which found be higher than polymeric counterpart (Mo‐DHTA‐P). This innovative design highlights potential metal‐embedded crystalline porous COFs advanced applications.
