摘要
Abstract Herein, the photocatalytic generation of an important solar fuel—H 2 O 2 —by a thiophene‐coupled anthraquinone (AQ) and benzotriazole‐based donor (D)–acceptor (A) polymer (PAQBTz) nanoparticles is systematically reported. The visible‐light active and redox‐active D–A type polymer is synthesized employing the Stille coupling polycondensation, and the nanoparticles are obtained by dispersing the PAQBTz polymer and polyvinylpyrrolidone solution, prepared in tetrahydrofuran to water. The polymer nanoparticles (PNPs) produce 1.61 and 1.36 mM mg −1 hydrogen peroxide (H 2 O 2 ) in the acidic and neutral media, respectively, under AM1.5G simulated sunlight irradiation ( λ > 420 nm) with ≈2% modified Solar to Chemical Conversion (SCC) efficiency after 1 h of visible light illumination in acidic condition. The results of the various experiments lay bare the different aspects governing H 2 O 2 production and indicate the H 2 O 2 synthesis through the superoxide anion‐mediated and anthraquinone‐mediated routes.
