Understanding the crucial roles of catalyst properties in ethyl acetate and toluene oxidation over Pt catalysts

Abstract

Platinum catalysts supported by metal oxides supports (CeO2-ZrO2, CeO2, ZrO2 and Al2O3) were prepared by the facile impregnation method. Significant differences in properties (medium strong acid density, Pt0 species content,...

Excellent Catalytic Performance of Ce–MOF with Abundant Oxygen Vacancies Supported Noble Metal Pt in the Oxidation of Toluene

“…Additionally, the CO 2 selectivity also reached 100% in a very short time and remained stable (Figure 7d), which indicated that Pt/MOF-BTC had a wonderful selectivity to CO 2 and excellent oxidation ability to intermediates. Table S3 demonstrated the catalytic activity for toluene combustion of several Pt catalysts compared with other Pt catalysts, such as Pt/ZrO 2 [57], Pt/Al 2 O 3 [58], and Pt/Mn 3 O 4 [59]. The activation or reaction temperature of Pt/MOF-BTC was lower for toluene oxidation.…”

Insights into Different Reaction Behaviors of Propane and CO Oxidation over Pt/CeO2 and Pt/Nb2O5: The Crucial Roles of Support Properties

“…There are many important oxides supports used in catalytic combustion, such as CeO 2 , ZrO 2 , Al 2 O 3 , Nb 2 O 5 , and TiO 2 , among others . For instance, the Pt catalyst supported by CeO 2 are widely used for CO oxidation.…”

“…There are many important oxides supports used in catalytic combustion, such as CeO 2 , ZrO 2 , Al 2 O 3 , Nb 2 O 5 , and TiO 2 , among others. 17 For instance, the Pt catalyst supported by CeO 2 are widely used for CO oxidation. Meunier et al pointed out that there was synergistic catalysis between Pt 0 and Pt n+ species for CO oxidation, that Pt 0 species were beneficial for CO adsorption, and that Pt n+ species promoted the activation of oxygen.…”

Excellent oxidation activity of toluene over core–shell structure Mn2O3@MnO2: role of surface lattice oxygen and Mn species

“…During the past decade, the problem of air pollution has become more and more serious, especially the emission of volatile organic compounds (VOCs) including alkanes, aromatic hydrocarbons, olefins, halogenated hydrocarbons, esters, aldehydes, ketones, etc 1,2 . VOCs not only cause plenty of environmental problems such as photochemical smog, toxic air emissions, ozone hole, PM 2.5 and so on, but also irreversible damage to the human body such as the respiratory system, eyes, skin, etc 3‐6 . In severe cases, VOCs can also cause cancer, teratogenesis and mutagenesis.…”

“…1,2 VOCs not only cause plenty of environmental problems such as photochemical smog, toxic air emissions, ozone hole, PM 2.5 and so on, but also irreversible damage to the human body such as the respiratory system, eyes, skin, etc. [3][4][5][6] In severe cases, VOCs can also cause cancer, teratogenesis and mutagenesis. Researchers are paying more and more attention to the control of VOC emissions.…”
