Catalytic feasibility of Ce-doped LaCoO3 systems for chlorobenzene oxidation: An analysis of synthesis method

A family of Ce-doped LaCoO 3 perovskites are presented as possible catalysts for Cl–VOCs elimination. These materials with different contents Ce were obtained through the citrate and reactive grinding methods. The insertion in original perovskite structure favours presence Co 2+ /Co 3+ /Ce 4+ redox pairs a higher content oxygen vacancies that enhances catalytic performance chlorobenzene combustion based on differential kinetics studies. by method presents high synthesized method. Thus, is feasible green chemistry alternative to obtain catalyst same from traditional Finally, stability samples was evaluated under total reaction conditions showing an excellent activity during 45 h time stream. prepared two methods (citrate grinding) present zero formation by-products. • synthesis use order active catalysts. combination substituted increases activity. Catalysts oxidize its oxidation products, without final intermediates. Differential kinetic studies corroborated capacity obtained. Samples s
