AuOx/Ce0.6Zr0.3Y0.1O2 nano-sized catalysts active for the oxidation of methane

Ce0.6Zr0.3Y0.1O2nanorod supported gold and palladium alloy nanoparticles: high-performance catalysts for toluene oxidation

“…[23,88]. The good reducibility of a catalyst was also thought to facilitate the redox process of the metal ions with multiple oxidation states, and hence promoting the oxidation of organics [54,55,89].…”

“…In another work [55], we measured the redox ability, oxygen mobility, OSC, and three-way catalytic performance of Ce 0. 6 [23]. By controlling the preparation conditions, we synthesized CZY solid solutions with different morphologies, in which the nanorod-like CZY sample possessed a high surface area and good low-temperature reducibility [56].…”

“…Among the catalysts investigated so far, the most efficient catalysts are the supported noble metal (e.g., Pd, Pt, and Au) catalysts [2][3][4][5][6][7][8][9], in which the supported Au nanoparticles (NPs) have demonstrated to be effective for the reactions involving a redox process [10][11][12][13][14][15][16]. Monometallic Au or Pd NPs were loaded on different supports, such as TiO 2 , which showed good catalytic activities for selective hydrogenation, CO oxidation, VOCs combustion, and selective catalytic reduction of NO [17][18][19][20][21][22][23][24]. The size (< 5 nm) of the Au particles plays a decisive role in dramatically enhancing the catalytic performance [25].…”

Development of Combustion Technology for Methane Emitted from Coal‐Mine Ventilation Air Systems

“…Nanosized AuO x /Ce 0.6 Zr 0.3 Y 0.1 O 2 (AuOx/CZY) catalysts were successfullyp roduced by adopting the cetyltrimethyl ammonium bromide (CTAB)-assistedh ydrothermal treatment method. [108] Thegold concentration on the solid catalyst was varied by using an ovel in situ reduction method. The characterization result confirmed that CZY and gold were nanosized particles,w ith diameters in the range of 5-50 and 2-20 nm, respectively.A mongt he catalysts investigated herein,t he 0.2 %A uOx/CZY catalyst appeared most active for methaneo xidation, with which 100 %c onversionw as achieveda ta bout 640 8C.…”

Pt or Pd-doped Au/SnO2 Catalysts: High Activity for Low-temperature CO Oxidation

“…Other researchers also reported the coexistence of Au 0 and Au 3? species in the Fe 2 O 3 -supported gold catalysts prepared by the co-precipitation method [21] and in the Ce 0.6 Zr 0.3 Y 0.1 O 2 -supported AuO x catalysts derived from the impregnation route [22]. To confirm the above assignments, we treated the 3Au/SnO 2 sample in a pure CO flow of 40 mL/min at 60°C for 1 h. Figure S3b shows the Au 4f XPS spectrum of the CO-pretreated 3Au/SnO 2 sample.…”
