Redox-induced controllable engineering of MnO2-MnxCo3-xO4 interface to boost catalytic oxidation of ethane

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: May 15, 2024

Abstract Multicomponent oxides are intriguing materials in heterogeneous catalysis, and the interface between various components often plays an essential role oxidations. However, underlying principles of how hetero-interface affects catalytic process remain largely unexplored. Here we report a unique structure design MnCoO x catalysts by chemical reduction, specifically for ethane oxidation. Part Mn ions incorporates with Co to form spinel 3- O 4 , while rests stay as MnO 2 domains create -Mn interface. Mn/Co ratio 0.5 exhibits excellent activity stability up 1000 h under humid conditions. The synergistic effects elucidated, which C H 6 tends be adsorbed on interfacial sites subsequently break C-H bonds reactive lattice layer. Findings from this study provide valuable insights rational efficient alkane combustion.
