Low-temperature carbon monoxide and propane total oxidation by nanocrystalline cobalt oxides

- Highly porous CoO(OH) was synthesized at RT by an innovative precipitation method.
- A heating at 250 °C converts CoO(OH) in Co3O4 without textural modifications.
- These materials are highly efficient for CO and C3H8 oxidation.
- A correlation was found between porous volume and catalytic activity.
- Our catalysts present the best activity ever reported for total oxidation of propane.
