Mayenite supported perovskite monoliths for catalytic combustion of methyl methacrylate

Zekai ZHANG, Zhijian KONG, Huayan LIU, Yinfei CHEN

Frontiers of Chemical Science and Engineering 2014, Volume 8, Issue 1,   Pages 87-94 doi: 10.1007/s11705-014-1410-5

Abstract: To improve their thermal stability, La Sr MnO cordierite monoliths are washcoated with mayenite, which is a novel Al-based material with the crystal structure of 12MO·7Al O (M= Ca, Sr). The monoliths are characterized by means of nitrogen adsorption/desorption, scanning electron microscopy, and X-ray diffraction. Catalytic performances of the monoliths are tested for methyl methacrylate combustion. The results show that mayenite obviously improves both the physic-chemical properties and the catalytic performance of the monoliths. Because mayenite improves the dispersity of La Sr MnO and also prevents the interaction between La Sr MnO and cordierite or -Al O , both crystal structure and surface morphology of La Sr MnO phase can thereby be stable on the mayenite surface even at high temperature up to 1050 oC. Under the given reaction conditions, La Sr MnO monolith washcoated with 12SrO·7Al O shows the best catalytic activity for methyl methacrylate combustion among all the tested monoliths.

Multivalent manganese oxides with high electrocatalytic activity for oxygen reduction reaction

Xiangfeng Peng, Zhenhai Wang, Zhao Wang, Yunxiang Pan

Frontiers of Chemical Science and Engineering 2018, Volume 12, Issue 4,   Pages 790-797 doi: 10.1007/s11705-018-1706-y

Abstract: A noble-metal-free catalyst based on both Mn O and MnO was prepared by using the dielectric barrier discharge technique at moderate temperature. The prepared catalyst shows a higher electrocatalytic activity towards the oxygen reduction reaction than the catalyst prepared by using the traditional calcination process. The enhanced activity could be due to the coexistence of manganese ions with different valences, the higher oxygen adsorption capacity, and the suppressed aggregation of the catalyst nanoparticles at moderate temperature. The present work would open a new way to prepare low-cost and noble-metal-free catalysts at moderate temperature for more efficient electrocatalysis.

Ultrasound-assisted co-precipitation synthesis of mesoporous Co3O4–CeO2 composite oxides for highly selective

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 8,   Pages 1211-1223 doi: 10.1007/s11705-022-2145-3

Abstract: The one-step highly selective oxidation of cyclohexane into cyclohexanone and cyclohexanol as the essential intermediates of nylon-6 and nylon-66 is considerably challenging. Therefore, an efficient and low-cost catalyst must be urgently developed to improve the efficiency of this process. In this study, a Co3O4–CeO2 composite oxide catalyst was successfully prepared through ultrasound-assisted co-precipitation. This catalyst exhibited a higher selectivity to KA-oil, which was benefited from the synergistic effects between Co3+/Co2+ and Ce4+/Ce3+ redox pairs, than bulk CeO2 and/or Co3O4. Under the optimum reaction conditions, 89.6% selectivity to KA-oil with a cyclohexane conversion of 5.8% was achieved over Co3O4–CeO2. Its catalytic performance remained unchanged after five runs. Using the synergistic effects between the redox pairs of different transition metals, this study provides a feasible strategy to design high-performance catalysts for the selective oxidation of alkanes.
