PMMA-templating generation and high catalytic performance of chain-like ordered macroporous LaMnO3 supported gold nanocatalysts for the oxidation of carbon monoxide and toluene

- Chain-like macroporous LaMnO3 is prepared by the PMMA-templating method.
- xAu/LaMnO3 is prepared by the PVA-protected reduction method.
- xAu/LaMnO3 possess high surface area and Oads content and good reducibility.
- xAu/LaMnO3 perform well in the oxidation of CO and toluene.
- There is a strong interaction between Au and LaMnO3.
