Low-temperature removal of toluene and propanal over highly active mesoporous CuCeOx catalysts synthesized via a simple self-precipitation protocol

- A facile and universal self-precipitation route for mesoporous metal oxides preparation.
- CuCeOx catalysts with high surface area and homogeneous mesostructure.
- Catalysts combined promoted reducibility and surface oxygen concentration.
- Mesostructured metal oxides with superior low-temperature catalytic efficiency.
- Catalysts possess remarkable enhanced reaction rate and selectivity.
