| 摘要 | This work reports a novel strategy to in situ grow TiO2 nanosheets on flexible Ti mesh as ideal support, and to modify CuO active components through multi-step methods. The CuO/TiO2/Ti monolithic catalyst can realize the complete CO oxidation at 110 degrees C without the assistance of any noble metal and the outstanding long-term stability can be also achieved. When using urea as deposition precipitant, CuO particle size will increase obviously with the reaction time longer than 6 h, which is adverse to the catalytic performance, showing the significant impact of CuO particle size on the CO oxidation capability. The deposition reaction carried out in different solutions is also investigated and the results show that CuO/TiO2/Ti catalysts synthesized in acid and alkaline condition exhibit superior catalytic performance owing to the high content of Cu1+/0 and adsorbed oxygen species (O-alpha) on surface, large surface area, and excellent redox capacity compared with that in reductive solution. More importantly, the as-synthesized CuO/TiO2/Ti monolithic catalysts show outstanding low-temperature performance and excellent long-term stability, indicating the overwhelming advantage of in situ grown catalysts. It is expected that the peculiar in situ growth technology is capable of extending to monolithic catalysts for multiple applications in the future. |
