Toluene Oxidation: CO₂ vs Benzaldehyde: Current Status and Future Perspectives

ACS Omega, Journal Year: 2024, Volume and Issue: 9(25), P. 26780 - 26804

Published: June 5, 2024

Toluene is a common and significant volatile organic compound (VOC). Although it finds extensive application in various industrial processes (chemical manufacturing, paint adhesive production, as solvent), creates huge environmental impact when emitted freely into the atmosphere. Two solutions were found to mitigate emission of this pollutant: total oxidation CO2 H2O selective benzaldehyde. This review discusses two main alternatives for tackling problem: converting toluene carbon dioxide by or benzaldehyde oxidation. It presents new catalytic advances, trends, advantages disadvantages both methods.

Highly Efficient Catalytic Oxidation of Glucose to Formic Acid over Mn-Mo Doped Carbon Nanotube

Molecules, Journal Year: 2025, Volume and Issue: 30(7), P. 1639 - 1639

Published: April 7, 2025

The production of formic acid (FA) from lignocellulose and its derived sugars represents a pivotal upgrading reaction in biorefinery. This work prepared Mn-Mo doped carbon nanotube composite catalyst for the catalytic oxidation glucose into FA an O2 atmosphere, under extremely low Mn (3.27%) Mo (0.40%) loading conditions, displaying comparable performance with traditional vanadium-based suffering toxicity issues. It was confirmed that doping led to formation MnMoOX increased contents low-valence species (Mn2+ + Mn3+), lattice oxygen (Olatt), surface adsorbed (Oads) based on various characterization methods, such as XRD, XPS, TEM ICP, which were beneficial improve performance. maximum yield 58.8% could be achieved over Mn9Mo1OX@MWCNT after 6 h at 140 °C, far more than obtained undoped MnOX@MWCNT (14.5%) identical conditions. Glyoxylic arabinose identified two main intermediates, suggesting transformation involved different paths. proved manganese-based green alternative via oxidation.

Nanoporous CeO₂-Decorated Cu-SmMn₂O₅ Composite Mullite Oxide Catalyst for Toluene Oxidation

ACS Applied Nano Materials, Journal Year: 2024, Volume and Issue: 7(2), P. 2010 - 2020

Published: Jan. 11, 2024

Mullite-type AMn2O5 materials represent a group of promising candidates to substitute noble metal catalysts for the catalytic removal volatile organic compounds (VOCs). When applied oxidation aromatic hydrocarbons such as toluene, exhibits undesirable performance due its poor intrinsic activity oxygen species, leading light-off temperature above 250 °C. In this work, we have developed synthesis route combining two-step calcination and cation-exchange process prepare nanoporous CeO2-decorated Cu-SmMn2O5 composite mullite oxide catalyst in toluene oxidation. The best performing sample reached 90% conversion at 190 °C, surpassing other transition catalysts. Comprehensive characterizations reveal that Cu ion doping into crystal lattice phase is achieved via process. design, surface CeO2 decoration promote reduction ability improve species accelerate Overall, work provides strategy with high VOCs, broadening industrial application prospects mullite-type materials.
