Insight into Interfacial Engineering for Enhancing the Synergistic Effect of Piezo-Photocatalytic Hydrogen Peroxide Production

Published: Jan. 1, 2024

Constructing heterojunctions represents a prevalent approach for enhancing piezo-photocatalytic performance, but it also remains an enigma due to contradictory charge polarity and poor active site. Here, in situ hydrothermal method was employed fabricate ZnIn2S4-BiOCl compact heterojunction with interfacial chemical bonding. Experimental theoretical calculations show that the newly formed bond (Bi-S bond) creates strong electronic effect between heterojunctions, which act as strain centers transfer channels increasing coordinated piezoelectric photoelectric fields thus transfer. In addition, bonding induces dynamic surface reconstruction redistribution of electron density, improving activation exchange reactants well lowering reaction barriers steps. Consequently, ZB-4 demonstrates exceptional photocatalytic pure water H2O2 performance (1987.33 μmol g-1 h-1), surpassing BiOCl by astounding 5.85 times. This study presents useful strategy positive coordination effect.

Abstract Because of its excellent catalytic activity and stability, perovskite materials are widely used in advanced oxidation processes to remove refractory organic pollutants. In this study, a series catalysts Pr 0.6 Sm 0.4 Co x Mn 1‐x O 3 (x = 0, 0.2, 0.4, 0.5, 0.6,0.8 1) with limited range effect prepared by sol–gel method the regulation strategy injecting active metal at B site crystal lattice catalyst MnO . Under optimal conditions, 0.8 0.2 /PMS/RhB system showed superior performance, removal rate Rhodamine (100 mg L −1 ) is close 100% within 40 min. addition, has wider pH (2‐10) tolerance still outstanding properties after multiple cycle tests. The quenching experiment EPR test confirmed that variety species produced system, singlet oxygen as leading path substances assisted promote efficient degradation wastewater. This study provides new reaction regulatory structural sites for design Fenton‐like systems based on novel oxides.
