Analysis of CeO2-Supported Ru Catalysts for an Efficient Catalytic Wet Air Oxidation of Reconstituted Tobacco Wastewater

Catalysts, Journal Year: 2025, Volume and Issue: 15(2), P. 109 - 109

Published: Jan. 23, 2025

CeO2-supported noble metal catalysts show great application potential in the catalytic oxidation of volatile organic compounds and hazardous wastewater. In this paper, an efficient Ru/CeO2 catalyst is developed by combining oxygen affinity metals redox supports for wet air (CWAO) reconstituted tobacco First, what factors affect performance are studied investigating effect (C, TiO2, Al2O3, CeO2) (Pt, Pd, Ru) on activity. Second, further enhanced tuning morphology CeO2 supports. The results indicate that Ru/CeO2-R (rod-like) highly active can reach a high TOC conversion 97.6% at 220 °C 1 h. contrast, conversions Ru/CeO2-MOF, Ru/CeO2-NP (nanoparticle), Ru/CeO2-C (cube-like) 93.3, 77.9, 68.2%, respectively. also presented good stability. be maintained approximately 85% four consecutive cycles. characterization better Ru dispersion, higher Ce3+ content, more surface reactive species, electron transfer between CeO2-R, from CeO2-R to main reasons best catalyst.

In situ Production of Hydroxyl Radicals via Three‐Electron Oxygen Reduction: Opportunities for Water Treatment

Angewandte Chemie, Journal Year: 2024, Volume and Issue: 136(40)

Published: July 15, 2024

Abstract The electro‐Fenton (EF) process is an advanced oxidation technology with significant potential; however, it limited by two steps: generation and activation of H 2 O . In contrast to the production via electrochemical two‐electron oxygen reduction reaction (ORR), three‐electron (3e − ) ORR can directly activate molecular yield hydroxyl radical (⋅OH), thus breaking through conceptual operational limitations traditional EF reaction. Therefore, 3e a vital for efficiently producing ⋅OH in situ, charting new path toward development green water‐treatment technologies. This review summarizes characteristics mechanisms ORR, focusing on basic principles latest progress situ efficient utilization modulation pathway, shedding light rational design catalysts, mechanistic exploration, practical applications water treatment. Finally, future developments challenges efficient, stable, large‐scale are discussed based achieving optimal regulation potential combine other

Novel S-Scheme Loofah Biochar/Mos2/G-C3n4 Heterojunctions with Efficient Photogenerated Carrier Separation and Transfer Capability: Effect, Mechanism and Application

Published: Jan. 1, 2025

The construction of S-scheme heterojunctions has drawn widespread attention within the photocatalysis field due to their capacity for efficient separation photogenerated carriers, leading excellent photo-oxidation-reduction performance. Herein, a novel loofah biochar/MoS2/g-C3N4 (LB/MS/CN) heterojunction was successfully constructed by ultrasonication in 50% ethyl alcohol and heat treatment N2 atmosphere. Degradation experiments showed that 5% LB/MS/CN ternary photocatalyst had optimal photocatalytic efficiency (96.4%) degradation rhodamine B (RhB), reaction rate (k) this (0.05420 min-1) 5.4 times unmodified CN (0.01001 min-1). Ultraviolet-visible diffuse reflectance spectra, Mott-Schottky, free radical trapping suggested carriers were transferred through structure. Consequently, co-catalytic action LB synergistic impact structure between MS led reduced carrier recombination rate. Furthermore, outstanding stability maintain RhB performance under various environmental conditions (H2PO4-, NO3-, SO42-, HCO3-, NaCl, HA, real water), showing good promise practical applications. Thus, work provides possible strategy purifying wastewater visible light.
