摘要
In this work, porous TiO2 nanotablets with rich oxygen vacancies were synthesized by thermal decomposition of MIL-125, and their hydrogen gas sensing performance has been investigated for the first time. In comparison with TiO2 microparticles prepared by the traditional sol-gel method, the metal-organic framework-derived porous TiO2 nanotablets have a larger specific surface area and oxygen vacancies, which can significantly boost hydrogen at room temperature. Furthermore, the gas-sensing mechanism of the MOFs-derived TiO2 nanotablets is well unraveled by experimental results and density functional theory (DFT) calculations. This study would provide a new perspective on TiO2-based nanomaterials for hydrogen detecting at room temperature.
