Cerium-containing catalyst exhibits excellent catalytic activity due to its special oxygen storage capacity, which makes the material exceptionally effective in catalytic applications. Metal organic frameworks (MOFs) has been a flourishing research theme and have provoked fascinated interest because of their versatile structures and interesting topologies. We report the study of cerium-containing catalysts derived from MOFs and their performance in toluene catalytic oxidation. Case 1: MnOx-CeO2 composite oxides. A series of MnOx-CeO2 oxides with various Mn content were prepared using CeBTC-MOF as sacrificial template towards catalytic oxidation of toluene. It was believed that MOFs-template method could prevent the aggregation of the particles and the uneven dispersion of the active constituent. Results showed that the composite oxides prepared by template method exhibited rod-shaped morphology, highly dispersed state, great specific surface area and nanocrystalline particles. In the process of incorporating Mn into MOF, Mn partly entered the lattice to form solid solution of Ce-Mn-O, while other Mn dispersed on the surface of CeO2. The state of the dispersed Mn included monolayer dispersion state and crystalline phase. Particularly, the strong interaction between CeO2 and dispersed Mn was the key factor affecting catalytic activity. Case 2:  [email protected] Ce-BTC. Pre-stabilized Pt nanoparticles synthesized by alcohol reduction were immobilized within Ce-BTC matrix, using in situ one-step strategy. Analysis demonstrated the integral structure and excellent crystallinity of [email protected] with no Pt nanoparticles aggregation as well as good thermal stability. The obtained [email protected] exhibited attractive catalytic activity for toluene oxidation, that the temperature of toluene complete oxidation below 170oC. Furthermore, [email protected] had good catalytic durability due to the framework structure was remain unchanged and no Pt nanoparticles aggregation was observed after reaction.
