Unveiling the Mechanism of Frictional Catalysis in Water by Bi₁₂TiO₂₀: A Charge Transfer and Contaminant Decomposition Path Study

Langmuir, Journal Year: 2022, Volume and Issue: 38(46), P. 14153 - 14161

Published: Nov. 7, 2022

Tribocatalysis, as a new approach in environmental purification, has drawn increasing attention the past few years. In this work, we successfully convert mechanical energy to chemical by Bi12TiO20, which was synthesized hydrothermal method. Under magnetic stirring, electrons transfer from surface of Bi12TiO20 polytetrafluoroethylene-sealed bar due their friction. Moreover, holes that remain on provide oxidation properties process for organic matter degradation. According series tests, it is noticed shape stirring and material reaction vessel have remarkable influence removal efficiency contaminants. Simultaneously, multiple tests reveal high stability Bi12TiO20. A great potential control water pollutants under dark conditions during collection ambient clearly demonstrated study.

Chemistry - An Asian Journal, Journal Year: 2023, Volume and Issue: 18(9)

Published: March 15, 2023

Abstract Catalysis plays a crucial role in all the major applications and challenges environment, including energy generation environmental remediation. Although photocatalysts electrocatalysts are useful addressing issues, they have some drawbacks, such as low efficiency easy charge recombination which limits their applications. Hence, it is imperative to design explore new catalytic techniques that include non‐photoresponsive catalysts. In this review, detailed possibilities, characteristics prospects of catalysts, piezocatalysts, thermocatalysts, pyrocatalysts, tribocatalysts along with hybrid catalysts described. The overall mechanism each technique its different fields generation, remediation, carbon dioxide reduction discussed.

Synergistic Enhancement of Photocatalytic CO₂ Reduction by Built‐in Electric Field/Piezoelectric Effect and Surface Plasmon Resonance via PVDF/CdS/Ag Heterostructure

Small, Journal Year: 2023, Volume and Issue: 19(52)

Published: Aug. 30, 2023

Photocatalytic reduction of CO2 using solar energy is an effective means to achieve carbon neutrality. However, the photocatalytic efficiency still requires improvements. In this study, polyvinylidene fluoride (PVDF) ferroelectric/piezoelectric nanofiber membranes are prepared by electrospinning. Cadmium sulfide (CdS) nanosheets assembled in situ on surface PVDF based coordination between F- and Cd2+ , then Ag nanoparticles deposited CdS. Because synergistic effect localized plasmon resonance built-in electric field PVDF, PVDF/CdS/Ag under visible light irradiation significantly higher than that any combination CdS, CdS/Ag, or PVDF/CdS. Under micro-vibration simulate air flow, three times static conditions, reaching 240.4 µmol g-1 h-1 . The piezoelectric caused micro-vibrations helps prevent from becoming saturated with carriers provides a continuous driving force for carrier separation.
