NO oxidation over supported Pt: Impact of precursor, support, loading, and processing conditions evaluated via high throughput experimentation

Oxidation of nitric oxide to nitrogen dioxide over Ru catalysts

“…Pt/SiO 2 [11][12][13] and Pt/Al 2 O 3 [13,14] were reported to be highly active for NO oxidation. The catalytic kinetics and the effects of preparation parameters on activities had been investigated in detail [11][12][13][14]. Although supported platinum catalysts show considerable activity for NO oxidation, the high cost of noble metal platinum materials restricts the application of supported Pt catalysts to a great extent.…”

Catalytic oxidation of NO over TiO2 supported platinum clusters I. Preparation, characterization and catalytic properties

“…However disappointedly, the reaction of NO oxidation is carried out under strong oxidizing conditions and the deactivation of platinum catalysts due to the formation of platinum oxides sometimes is unavoidable. The catalytic deactivation of platinum catalysts by O 2 and NO 2 due to oxides formation in the reaction has been proved and investigated in details [9][10][11][12]. In the research of support effect on the state of platinum catalysts, Yoshida et al [15] suggested that electrophilic acidic support suppress the formation of platinum oxides through electrons donation from support to platinum.…”

“…Platinum catalysts have been extensively investigated in the past years [7][8][9][10][11][12][13][14] and up to now platinum catalysts are still regarded as model catalysts for NO oxidation. The catalytic and kinetic results for NO oxidation over platinum catalysts under different feed composition, e.g.…”

Improvement of thermal stability of NO oxidation Pt/Al2O3 catalyst by addition of Pd

“…Those methods need the catalytic oxidation of NO to NO 2 and various catalysts have been reported for this reaction [1,2,[9][10][11][12][13][14][15]. Among catalyst elements Pt is known to show high performance for this conversion and has already been commercially available.…”
