Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: Oct. 23, 2023

The regulation of heterogeneous material properties to enhance the peroxymonosulfate (PMS) activation degrade emerging organic pollutants remains a challenge. To solve this problem, we synthesize S-scheme heterojunction PBA/MoS2@chitosan hydrogel achieve photoexcitation synergistic PMS activation. constructed photoexcited carriers undergo redox conversion with through transfer pathway driven by directional interface electric field. Multiple pathways greatly reactive oxygen species generation, leading significant increase in doxycycline degradation rate. Meanwhile, 3D polymer chain spatial structure chitosan is conducive rapid capture and electron transport advanced oxidation process, reducing use transition metal activator limiting leaching ions. There reason believe that regulated will provide new perspective for future design research on enhancing heterologous catalysis process.

Tempospatially Confined Catalytic Membranes for Advanced Water Remediation

Advanced Materials, Journal Year: 2024, Volume and Issue: 36(37)

Published: Feb. 12, 2024

Abstract The application of homogeneous catalysts in water remediation is limited by their excessive chemical and energy input, weak regenerability, potential leaching. Heterogeneous catalytic membranes (CMs) offer a new approach to facilitate efficient, selective, continuous pollutant degradation. Thus, integrating filtration with heterogeneous advanced oxidation processes (AOPs) can promote thermodynamic kinetic mass transfers spatially confined intrapores diffusion‐reaction processes. Despite the remarkable advantages CMs, engineering practically restricted due fuzzy design criteria for specific applications. Herein, recent advances CMs are critically reviewed flow tempospatially proposed. Further, state‐of‐the‐art CM materials mechanisms reviewed, after which tempospatial confinement comprising nanoconfinement effect, interface transfer emphasized, thus clarifying roles construction performance optimization CMs. Additionally, fabrication methods based on pore sizes summarized an overview evaluations presented. Finally, future directions research treatment,

Confinement boosted heterogeneous advanced oxidation processes

Chemical Engineering Journal, Journal Year: 2023, Volume and Issue: 472, P. 144861 - 144861

Published: July 25, 2023

Confined catalysts with large surface areas and adjustable pore channel sizes have been recently used in advanced oxidation processes (AOPs) for water wastewater treatment. Typically, a confinement scale depends on the geometric structure of catalyst. In environment AOPs, hydrogen bond number, ionic hydration diffusion molecules, adsorption energy chemical length oxidants as well local concentrations migration distances active species can be strikingly affected, turn influencing catalytic degradation efficiency. catalysis will generally enhance interaction between pollutants, increasing reaction kinetics improving contaminant removal compared traditional non-confined catalysis. this review, we firstly summarized behaviors different confined systems.
