Catalytic oxidation of toluene over LaBO3 (B= Fe, Mn and Co) and LaCo0.7B′0.3O3 (B′= Fe and Mn) perovskite-type
In this paper, LaBO3 perovskite type catalyst formulations were prepared by sol-gel auto combustion method using citric acid as the fuel. Activity of catalysts was tested in catalytic oxidation of toluene as a model of volatile organic compounds. LaCoO3 perovskite formulation showed the highest activity among LaBO3 (Fe, Mn and Co) perovskite catalysts. So, LaCoO3 perovskite based catalyst was s...
متن کاملPhotocatalytic Oxidation Processes for Toluene Oxidation over TiO2 Catalysts
Gas-solid heterogeneous photooxidation of toluene over TiO2 catalyst was studied to investigate the factors controlling the catalytic activities. The toluene photooxidation behavior on TiO2 was strongly affected by the formation and oxidation behavior of intermediate compounds on TiO2, and their accumulation decreased the reaction rate for toluene photooxidation. The formation and oxidation beh...
متن کاملLow-temperature CO oxidation over Cu/Pt co-doped ZrO2 nanoparticles synthesized by solution combustion
Zirconia (ZrO2) nanoparticles co-doped with Cu and Pt were applied as catalysts for carbon monoxide (CO) oxidation. These materials were prepared through solution combustion in order to obtain highly active and stable catalytic nanomaterials. This method allows Pt2+ and Cu2+ ions to dissolve into the ZrO2 lattice and thus creates oxygen vacancies due to lattice distortion and charge imbalance. ...
متن کاملCalculations of CO Oxidation over a Au/TiO2 Catalyst: A Study of Active Sites, Catalyst Deactivation, and Moisture Effects
The reaction mechanism of CO oxidation on Au/TiO2 catalysts remains elusive. Here, we employ density functional theory calculations to gain an understanding of several important aspects of the system, including CO adsorption, the active oxygen species, catalyst deactivation, and the promoting effect of moisture on catalytic activity. Distinct from previous theoretical studies, which tend to add...
متن کاملPartial oxidation of toluene by O2 over mesoporous Cr–AlPO
The synthesis of mesoporous Cr–AlPO was carried out under hydrothermal conditions. Characterisation of the catalyst was done with low angle XRD, N2 adsorption, UV–VISDRS, ESR and thermal analysis. The catalytic activity was tested for partial oxidation of toluene with molecular oxygen in vapour phase. It was observed that Cr–AlPO functions both as acid and redox catalyst. 2002 Elsevier Science ...
