Methanol oxidative decomposition over zirconia supported silver catalyst and its reaction mechanism

Synthesis of tetragonal zirconia in mesoporous silica and its catalytic properties for methanol oxidative decomposition

“…The addition of Ag component enhances the oxidation step of methoxy species to CO 2 due to the formation of active oxygen species on Ag species. 32 In addition, in situ Fourier Transform Infrared Spectroscopy (FTIR) demonstrates that the MeOH adsorption sites are on the zirconia support with high crystallinity. Therefore, to elucidate the adsorption property of MeOH on the synthesized zirconia, we have evaluated the catalytic property of zirconia for MeOH oxidation.…”

“…1 In addition to the metastable tetragonal, monoclinic, and tetragonal zirconia and hydrated zirconia that can be applied to a catalyst material have also been reported in the literature. [32][33][34][35] In particular, we reported on the catalytic property of zirconia-supported Ag catalysts for methanol (MeOH) oxidation. 32 Based on this background, in the present work, the synthesis of zirconia by the hard template method using KIT-6 have been conducted using various preparation conditions, such as zirconium source, amount of introduced zirconia, calcination temperature, and meso-pore size of silica, and the crystal growth behavior of the synthesized zirconia have been studied.…”

AgAuPd/meso-Co3O4: High-performance catalysts for methanol oxidation

“…There have been several works on the oxidation of methanol over various catalysts in the literature. Our 0.68Ag0.75Au1.14Pd/meso-Co3O4 sample showed a methanol reaction rate at 100 °C of 0.99 mol gcat -1 s -1 , which was higher than that (0.01 mol gcat -1 s -1 ) over meso-Cr2O3 [30], that (0.03 mol gcat -1 s -1 ) over wormhole-like Fe2O3 [46], that (0.11 mol gcat -1 s -1 ) over meso-Co3O4 [47], that (0.60 mol gcat -1 s -1 ) over 12 wt% MnOx/3DOM LaMnO3 [48], that (0.45 mol gcat -1 s -1 ) over 2 wt% Ag/CeO2 [49], and that (0.88 mol gcat -1 s -1 ) over 0.1 wt% Pd/5.0 wt% Ag/35CZA [50], but lower than that (3.50 mol gcat -1 s -1 ) over 0.8% Pd-Pt/CeO2-Al2O3-TiO2 [14].…”

Oxidative decomposition of methanol in a vibroacoustic fluidized bed of Ag-coated cenosphere core-shell catalyst

“…There are two types of catalysts used in catalytic oxidation: metal oxides and noble metals 15 . Authors of numerous papers show that metals such as platinum, ruthenium, gold and silver are active in the processes of oxidative decomposition of methanol 16,17 . In this study, silver was used as the catalyst.…”
