WO3@TP无机@有机S型光催化剂用于促进产H2O2
WO3@TP inorganic@organic S-scheme photocatalyst for boosting H2O2 production
摘要
Abstract
Photocatalysis of H2O2 production using O2 and water is a cost-effective and environmental process,but developing high-performance photocatalysts is still a challenge.Herein,a WO3@polymer S-scheme photocatalyst was synthesized by in situ growing the Schiff-base polymer,tris-(4-aminophenyl)amine(TAPA)-terephthaldicarboxaldehyde(PDA)(labeled as TP)on the surface of WO3 nanofibers(WO3@TP)at room temperature.The obtained WO3@TP S-scheme heterojunction exhibited rapid carrier separation ability and short photogenerated carriers transfer distance.The optimal WO3@TP composite(WT-10)realized the H2O2 evolution rate of 3242 μmol g-1 h-1,which was 137.3 and 4.6-fold higher than bare WO3 and TP,respectively.The combination of advanced characterizations regarding in situ irradiated X-ray photoelectron spectroscopy(ISI-XPS),theoretical calculation,and femtosecond transient absorption spectroscopy(fs-TAS)validates the charge transfer mechanism within the WO3@TP S-scheme heterojunction.The occurrence of a dual-channel pathway(O2 reduction reaction(ORR)and water oxidation reaction(WOR)within the reaction system has been confirmed via electron paramagnetic resonance(EPR)and in situ diffuse reflectance infrared Fourier transform spectroscopy(DRIFTS),thereby contributing to the highly efficient H2O2 evolution.This study not only gives an in-depth understanding of the ultrafast charge migration behavior in S-scheme heterojunction but also offers the rational design of inorganic@organic photocatalysts applied to solar-driven H2O2 production.关键词
