Low-temperature and stable CO oxidation of Co3O4/TiO2 monolithic catalysts

Highly efficient Co3O4/TiO2 monolithic catalysts with enhanced stability were in-situ grown on Ti mesh for CO oxidation, which could completely oxidize CO at 120 °C. The comprehensive catalytic performance is competitive to some noble metal catalysts and conventional Co3O4 powder catalysts, which holds great potential toward industrial applications. Meanwhile, the in-situ synthesis strategy of Co3O4/TiO2 monolithic catalysts on flexible mesh substrate in this work can be extended to the development of a variety of oxide-based monolithic catalysts towards diverse catalysis applications.
