Cooperative Coupling of H₂O₂ Production and Organic Synthesis over a Floatable Polystyrene‐Sphere‐Supported TiO₂/Bi₂O₃ S‐Scheme Photocatalyst

Advanced Materials, Год журнала: 2022, Номер 34(38)

Опубликована: Авг. 9, 2022

Cooperative coupling of photocatalytic H2 O2 production with organic synthesis has an expansive perspective in converting solar energy into storable chemical energy. However, traditional powder photocatalysts suffer from severe agglomeration, limited light absorption, poor gas reactant accessibility, and reusable difficulty, which greatly hinders their large-scale application. Herein, floatable composite are synthesized by immobilizing hydrophobic TiO2 Bi2 O3 on lightweight polystyrene (PS) spheres via hydrothermal photodeposition methods. The not only transparent, but also upgrade the contact between reactants photocatalysts. Thus, step-scheme (S-scheme) /Bi2 photocatalyst exhibits a drastically enhanced yield 1.15 mm h-1 decent furfuryl alcohol conversion to furoic acid synchronously. Furthermore, S-scheme mechanism dynamics systematically investigated situ irradiated X-ray photoelectron spectroscopy femtosecond transient absorption spectrum analyses. In Fourier transform infrared density functional theory calculations reveal evolution. ingenious design furnishes insight maximizing reaction kinetics provides new route for highly efficient heterogeneous catalysis.
