“…Among single or mixed transition metal oxides, perovskite-type oxides with general formula ABO 3 (A and B represent a lanthanide and/or alkaline earth metal ion and a transition metal ion, respectively) have been found to be e®ective catalysts for numerous VOCs combustion. 5,6 LaMnO 3 is an extremely welcome ABO 3 catalyst investigated so far. In the past several decades, the solid-state reaction, 7 combustion, 8 sol-gel, 9 co-precipitation, 10 hydrothermal 11 and biotechnological methods 12 were employed to synthesize lanthanum manganate catalyst.…”

La 1Àx Sr x MnO 3À@ (LSMO) and LaMnO 3þ@ (LMO) nanoparticle catalysts have been synthesized via a one-step molten salt route. It was found that the partial substitution of lanthanum by strontium had a promoting e®ect on the catalytic performance for toluene oxidation. Under the condition of toluene concentration ¼ 1000 ppm, toluene/O 2 molar ratio ¼ 1=200 and the space velocity ¼ 20000 mL/(g h), the temperature required for 50% and 90% toluene combustion conversion was 150 C and 205 C over LSMO catalyst, respectively. It is concluded that the oxygen vacancy, the molar ratio Mn 4þ /Mn 3þ on the surface and the speci¯c surface area contribute to the improved catalytic performance of the LSMO nanoparticle materials via a one-step molten salt method.

“…19,20 Moreover, Liang et al evaluated that Ba doped La-Ba-Ni mixed oxide catalysts for total oxidation of chlorinated hydrocarbons. 21 Compared with Ba free catalyst, Ba doping promoted the catalytic activity and La 0.5 Ba 0.5 NiO 3 exhibited the best performance. Bhavani et al studied CO 2 reforming of methane by using Ba substituted LaMnO 3 perovskite and found that the optimal level of Ba substitution was 0.1 and 0.15 (Ba/Mn), which showed the highest CH 4 and CO 2 conversion, syngas selectivity and robust maintenance of these performances with little coke formation.…”

Chlorinated volatile organic compounds (CVOCs) with strong stability, poor reactivity and high toxicity in waste gases are emitted into the atmosphere from many industrial operations, which has caused sustained harm to both human health and atmospheric environment. Catalytic combustion is regarded as one of the most effective methods to eliminate CVOCs due to its high removal efficiency, low energy consumption and low production of secondary pollutants. However, the screening of efficient catalysts (i.e. low cost, high activity and durability) still remains challenging. In this review, recent developments on catalytic combustion of CVOCs, including catalysts, reaction condition, catalytic reaction mechanism, deactivation reasons and regeneration methods are summarized. It is emphasized that the active components, structures and supports of catalysts have significant effects on their activity, selectivity, stability and longevity. In addition, it is pointed out that catalyst deactivation is closely related to chlorine poisoning, sintering, carbon deposition and metal active phase leaching. Compared with other catalysts, perovskite‐type composite oxides and spinel‐type composite oxides have shown to be promising materials in the catalytic combustion of CVOCs due to their particular structure and nature (e.g. surface area, redox property and surface acidity). Thereafter, the outlooks on catalytic combustion of CVOCs are also presented in this article based on the studies in the literature, which offer influential information for further research on the treatment technology of CVOCs. © 2020 Society of Chemical Industry
