H₂O₂ Production: Copolymer of Phenylene and Thiophene toward a Visible‐Light‐Driven Photocatalytic Oxygen Reduction to Hydrogen Peroxide (Adv. Sci. 5/2021)

In article number 2003077, Kouki Oka, Hiroyuki Nishide, and Bjorn Winther‐Jensen demonstrate that metal‐free copolymer of phenylene and thiophene works as a visible‐light‐harvester and highly selective and robust catalyst for the oxygen reduction to H(2)O(2). A visible‐light‐illuminated polymer layer in combination with a MnOx catalyst exhibits the steady and rapid H2O2 production without bias voltage. [Image: see text]
