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

Focus on the modified CexZr1−xO2 with the rigid benzene-muti-carboxylate ligands and its catalysis in oxidation of NO

“…The conversion decreased slowly as the result of the decomposition of NO 2 at 350-400 • C. In some previous study, NO conversion reached only about 30% at 450 • C in the condition of GHSV = 30,000 h −1 over Ce x Zr 1−x O 2 [51]. In other studies, NO conversion reached about 60% at 150 • C over Mn-Ce-O x catalysts [52], and reached about 90% at 300 • C over Pt/TiO 2 [53]. Due to the low SO 2 resistance over Mn-based catalysts and the high cost for preparation over Pt-based catalysts, these catalysts could not be applied for the NO x removal in the coal power plant, but they could be applied for other NO x removal, such as automobile exhaust treatment and diesel oxidation.…”

Low temperature catalytic oxidation of nitric oxide over the Mn–CoOx catalyst modified by nonthermal plasma

“…Various techniques have been developed for the elimination of NO x from stationary sources, such as selective catalytic reduction (SCR) [3], selective non-catalytic reduction (SNCR) [4], direct decomposition [5], and non-thermal plasma (NTP) [6]. The catalytic oxidation of NO to NO 2 has been focused on due to its key step for many De-NO techniques [7][8][9]. With the appropriate ratio of NO/NO x = 50%-60% by using efficient catalysts, the great NO x removal efficiency could be achieved by the further absorption with the adsorbent or the absorption liquid [10].…”

Catalytic oxidation of NO over TiO2 supported platinum clusters. II: Mechanism study by in situ FTIR spectra

“…The detailed preparation process of Pt/TiO 2 by photo-deposition can be found in our previous work [8]. Briefly, 2 mM H 2 PtCl 6 solution containing ca.…”

“…In our previous work [8], we reported that Pt/TiO 2 catalyst prepared by photo-deposition exhibited remarkable activity for NO oxidation even in the presence of SO 2 . In the present work, the surface species formed during the NO oxidation under different conditions (in the absence/presence of SO 2 ) over Pt/TiO 2 prepared by photo-deposition are investigated by in situ FTIR spectroscopy.…”
