A family of Ce-doped LaCoO₃ perovskites are presented as possible catalysts for Cl–VOCs elimination. These materials with different contents of Ce were obtained through the citrate and the reactive grinding methods. The insertion of Ce in the original perovskite structure favours the presence of Co²⁺/Co³⁺ and Ce³⁺/Ce⁴⁺ redox pairs and a higher content of oxygen vacancies that enhances the catalytic performance in chlorobenzene combustion based on differential kinetics studies. The family obtained by the grinding method presents a performance as high as that synthesized by citrate method. Thus, the reactive grinding is a feasible green chemistry alternative to obtain a catalyst with the same performance as that obtained from traditional methods. Finally, the stability of samples was evaluated under total combustion reaction conditions showing an excellent activity during 45 h time on stream.

Ce 掺杂的 LaCoO ₃钙钛矿家族被提出作为消除 Cl-VOCs 的可能催化剂。这些不同Ce含量的材料是通过柠檬酸盐和反应研磨法获得的。Ce在原始钙钛矿结构中的插入有利于Co ²⁺ /Co ³⁺和Ce ³⁺ /Ce ^4+的存在基于微分动力学研究，氧化还原对和更高含量的氧空位增强了氯苯燃烧中的催化性能。研磨法得到的族，其性能与柠檬酸盐法合成的族一样高。因此，反应性研磨是一种可行的绿色化学替代方法，可以获得与传统方法相同性能的催化剂。最后，在总燃烧反应条件下评估样品的稳定性，在 45 小时的运行时间内显示出优异的活性。
