La-Mn-O perovskite catalyst was successfully prepared by microwave irradiation processing using only several minutes for heat treatment, and characterized by XRD, SEM, XPS, H 2 -TPR and O 2 -TPD. The catalyst by microwave irradiation processing with 6 min, mainly nonstoichiometric excess oxygen LaMnO 3.15 phase, shows excellent catalytic performance. Compared with the sample prepared by conventional method, it possesses relative higher surface area, the increase in Mn 4? and oxygen vacancy content and the enhancement in the mobility of lattice oxygen which play an important part in the methane combustion.

Most of cobalt-doped carbon-based electrocatalysts have good activity for the hydrogen evolution reaction (HER). However, the bond form of cobalt atoms often restricts the improvement of the activity and stability...
