A mechanistic study of the sulfur tolerance of Cu–V mixed oxides in toluene catalytic combustion

Effect of Small Molecular Organic Acids on the Structure and Catalytic Performance of Sol–Gel Prepared Cobalt Cerium Oxides towards Toluene Combustion

“…Various methods, including sol-gel technique [21], co-precipitation method [22], and hydrothermal process [23], have been developed to synthesize metal oxides catalysts. Among them, the sol-gel method has been extensively studied in the synthesis of mixed metal oxides for the complete oxidation of VOCs, such as Co-Ce [21], Ce-Ti [24], Cu-V [25], Cu-Ce [26], and Ce-Fe [27] mixed metal oxides. As revealed in [28], the sol-gel process consists of hydrolysis and condensation reactions of metal precursors.…”

Dopant-driven tuning of toluene oxidation and sulfur resistance at the B-site of LaCo1−xMxO3 (M = Fe, Cr, Cu) perovskites

“…[25][26][27] Also, Cu-doped catalysts have enhanced reducibility while exhibiting higher activity and selectivity for SO 2 reduction to elemental sulfur. 18,28,29 Cr doping makes the catalysts less prone to adsorb SO 2 and more resistant to sulfur poisoning, and Cr 2 O 3 showed extremely stable activity even in the presence of sulfur compounds for a real coke oven facility emission. 30,31 In addition, doping elements such as Sr and Ce can also provide rational sulfur protection for catalysts.…”
