Total oxidation of ethanol over Au/Ce0.5Zr0.5O2 cordierite monolithic catalysts

Recent Advances in the Catalytic Oxidation of Volatile Organic Compounds: A Review Based on Pollutant Sorts and Sources

“…13.2 nm (T50 = 120 °C). 1017 Recently, Lu and co-workers 1018 reported an efficient, economic and simple strategy for the synthesis of Pt/TiO2 monolith catalysts, which involved spraying a dispersed Pt/TiO2 liquid on different substrates (Fig. 28).…”

“…6.7 nm) and was more active in ethanol destruction (T 50 = 80 °C) than the AuCeZr catalyst, which had a average Au particle size of around 13.2 nm (T 50 = 120 °C). 1017 Recently, Lu and co-workers 1018 reported an efficient, economical, and simple strategy for the synthesis of Pt/TiO 2 monolith catalysts, which involved spraying a dispersed Pt/TiO 2 liquid on different substrates (Figure 28). This study revealed that a Pt/TiO 2 cordierite monolithic catalyst, which had a Pt loading of 0.1 wt‰, exhibited excellent catalytic activity (T 90 = 212 °C; GHSV = 3000 h −1 ) and stability (without deactivation during a 120 h test) for the oxidation of toluene.…”

Activated Carbon from Renewable Material as an Efficient Support for Palladium Oxidation Catalysts

“…Considering the Mars‐van Krevelen reaction mechanism, the reducibility of the catalyst surface is a key factor for the activity of the catalysts in oxidation reactions. We have shown earlier that for some types of catalysts a good correlation can be found between H 2 ‐TPR profiles of the catalysts and their performance in ethanol oxidation . H 2 ‐TPR profiles of the CPH‐AC support and corresponding Pd catalysts are illustrated in Fig.…”

“…They act as greenhouse gases and control the rate of oxidant formation during the production of ground‐level ozone . Catalytic oxidation is recognized as an efficient, cost‐effective, and environmentally friendly way to treat VOC emissions . Total catalytic oxidation of VOCs especially at low concentrations is a promising method to convert VOCs to water and carbon dioxide.…”

Hydrothermal Deposition as a Novel Method for the Preparation of Co-Mn Mixed Oxide Catalysts Supported on Stainless Steel Meshes: Application to VOC Oxidation

“…In the second step, the (Mn,Co)O solid solutions are reduced to metallic cobalt and MnO. Similar behavior can be observed for other Co-Mn oxide catalysts.We reported previously a good correlation between H 2 -TPR pro les and performance of the catalysts in ethanol oxidation(Gaálová et al, 2019, Topka &Klementová, 2016. The abovementioned correlation of catalysts reducibility with catalytic performance of Co-Mn mixed oxide catalysts points to the redox (Mars -van Krevelen) reaction mechanism.…”
