文摘
- •
3DOM SiO2 with ordered mesoporous walls is synthesized via the PMMA-templating route.
- •
zMnOx/3DOM SiO2 is prepared using the incipient wetness impregnation method.
- •
yAu/zMnOx/3DOM SiO2 is prepared via the PVA-protected reduction route.
- •
0.93Au/11.2MnOx/3DOM SiO2 performs well in the oxidation of toluene.
- •
Oads content, reducibility, and noble metal–oxide interaction govern the catalytic activity.
