| Abstract | The template-free construction of hollow multiporous materials with hierarchically multiporous walls, unique morphologies, and functionalities remains a great challenge in materials science. Here, we describe a facile template-free approach to synthesize hollow multiporous-walled CeO2 (HMW-CeO2) nanospheres. The HMW-CeO2 nanosphere possesses a hierarchically multiporous wall, with pore sizes ranging from micropores to mesopores, centered at 0.43, 4.2, and 14.3 nm. The CuO loaded HMW-CeO2 support (HMW-CuO@CeO2) is evaluated for its catalytic activity in a CO oxidation reaction. The HMW-CuO@CeO2 support exhibits a higher catalytic activity than all of the other CeO2 catalysts. The results show a low T-100 of about 60 degrees C (the temperature at which 100% CO conversion has been achieved) and high stability, with negligible decrease in the CO conversion during 12 h of reaction. Overall, it provides a simple, low-cost and mass-productive method for the preparation of highly active catalysts for CO oxidation. |
