Tuning performance of Pd/Sn0.9Ce0.1O2 catalyst for methane combustion by optimizing calcination temperature of support

Total Oxidation of Light Alkane over Phosphate-Modified Pt/CeO2 Catalysts

“…Oxides of transition metals (e.g., Cu, Mn, Co, and Ni) and supported noble metals (Pt, Pd, Au, and Ru) are widely employed as catalysts for the oxidation of light alkanes. − Compared with transition metal oxides, supported noble metal catalysts, particularly Pt and Pd, have higher activity and are more widely used in industrial applications. Generally, apart from the states of the active sites of noble metals, good redox activity and strong acidity are highly conducive to improve the catalytic activity in the oxidation of light alkanes.…”

Optimizing the Microstructure of SnO2–CeO2 Binary Oxide Supported Palladium Catalysts for Efficient and Stable Methane Combustion

“…11,13 Therefore, the Ce 1−x Sn x O 2 and supported Pd catalysts have been applied to CO, CH 4 , or other oxidation reactions. As reported, the ratio of Sn/Ce, 10,13,14 the preparation route, 15−17 Ce 1−x−y Sn x Pd y O 2−δ ) 18,19 are crucial in determining the structure, property, and catalytic performance of catalysts. Although Ce 1−x Sn x O 2 can be beneficial for the oxidation reactions, their thermal stability is still insufficient and decomposition occurs at high temperatures (>600 °C).…”

“…The support calcined at 1100 °C consisted of mixed phases of CeO 2 and SnO 2 rather than solid solutions, which enhanced the oxygen mobility of supports, the reducibility of PdO, and the ratio of active Pd 2+ . 14 Inspired by the above thermal activation of SnO 2 −CeO 2 binary oxide supported Pd catalysts, it is expected to prepare highperformance Pd-based catalysts by optimizing the microstructure and compositions of supports with SnO 2 and CeO 2 phases. Besides, despite the Pd x Ce 1−x O 2−δ and Pd x Sn 1−x O 2−δ solid solutions receiving much attention, 9,20,21 it has yet to be determined the effect of the SnO 2 /CeO 2 ratio in binary oxides on the formation of Pd x Ce 1−x O 2−δ and Pd x Sn 1−x O 2−δ solid solutions and whether the combination of above two solid solutions could promote the catalytic performance toward methane combustion.…”

Research progress on methane conversion coupling photocatalysis and thermocatalysis

“…[1][2][3][4][5][6] The abundant production and reserves of natural gas are beneficial to producing the valueadded chemicals, but also cause the problem of global warming. 5,[7][8][9][10] Therefore, the efficient conversion of methane is highly desired from aspects of the environmental protection and high-efficacy utilization of fossil fuel.…”
