摘要

•Mn-Al oxides are synthesized by a hydrolysis-driven redox-precipitation method.•The enhanced OMS-2 phase and surface property are adjusted by Al/Mn molar ratio.•Abundant olatt and Mn3+with weaker Mn-O bond contribute to excellent activity.•The reaction mechanism is revealed by PTR-MS and in situ DRIFTS.
