Activation of Pt/SnO2 catalyst for catalytic oxidation of volatile organic compounds

Influences of heat-treatment and measurement atmosphere on the electrochemical property of Pt–SnO device

“…Besides, the interdiffusion of metal ions occurs at the interface of Pt/SnO x during reduction at high temperatures, resulting in the formation of intermetallic compounds (PtSn, Pt 3 Sn, etc.) [1,2,4,5]. Thus, in the present study, the reduction treatment at 200 • C gave rise to the diffusion of hydrogen and metal elements into constituent materials.…”

“…Moreover, many efforts have been devoted to their characterization to elucidate the microstructure, electronic state, adsorption property of reaction gas and so on, because these characteristics strongly affect the catalytic activity. We have focused on platinum catalyst supported on tin oxide (Pt/SnO 2 ) for the combustion of chemicals and the electrochemical reaction in polymer electrolyte fuel cells [1][2][3]. The microstructural changes in this catalyst induced by reduction and oxidation treatments were also noticeable [4,5].…”

“…Moreover, the electronic state of Pt varied in response to these structural changes. It was concluded that the catalytic activity of Pt/SnO 2 for CO and VOC oxidation was strongly affected by the microstructure at the Pt-SnO 2 interface and the electronic state of Pt species [1,2].…”

Catalytic oxidation of toluene over a porous Co3O4-supported ruthenium catalyst

“…10,11 In recent years, various catalysts have been used for the complete oxidation of VOCs, such as noble metals, [11][12][13][14][15] transition metal oxides, [16][17][18][19][20] and perovskite-type oxides. [21][22][23][24][25] Supported platinum and palladium materials are well established as efficient catalysts for complete oxidation of VOCs, [26][27][28][29][30] whereas their wide applications are limited due to the high costs. Transition metal oxides have been increasingly studied as the catalysts for oxidation of VOCs in single or mixed metal oxides formations, [31][32][33] usually showing lower catalytic activities than noble metals.…”

Nanostructured copper, chromium, and tin oxide multicomponent materials as catalysts for methanol decomposition: 11C-radiolabeling study

“…However, tin oxide based materials have received much less attention in catalysis. There are only few reports where the catalytic activity of these materials in oxidative dehydrogenation of hydrocarbons [2][3][4], selective catalytic reduction of NO x by hydrocarbons [5][6][7] or CO [6], low temperature oxidation of CO [8,9] or methane [10,11], volatile organic compounds combustion [12][13][14], and methanol steam reforming [1,15] was tested. It was discussed that the crucial point in catalytic behavior of SnO 2 concerned its easy reducibility leading to the simultaneous existence of Sn 2+ and Sn 4+ surface sites and a propensity to generate oxygen defects during thermal treatment [1].…”
