A surface reconstruction route for increasingly improved photocatalytic H₂O₂ production using Sr₂Bi₃Ta₂O₁₁Cl.

ABSTRACT: Photocatalytic hydrogen peroxide (H₂O₂) generation is attractive for the chemical industry and energy production. However, photocatalysts generally deteriorate significantly during use to limit their application. Here we present highly active Sr₂Bi₃Ta₂O₁₁Cl single-crystal nanoplates for conversion of O₂ to H₂O₂ using ambient air with a production rate of ∼3 mmol h^-1 g^-1 (maximum 17.5% photon conversion). Importantly, Sr₂Bi₃Ta₂O₁₁Cl is not only stable during 30 days of H₂O₂ production but also gets consistently activated to increase the H₂O₂ yield by >244%, unlike any other catalyst fo
