Defect Dominated Hierarchical Ti-Metal-Organic Frameworks via a Linker Competitive Coordination Strategy for Toluene Removal |
| 초록 |
Construction of a hierarchical pore structure in Metal-Organic Frameworks (MOFs) can improve the accessibility of active sites and facilitate mass diffusion to enhance their adsorption and catalytic efficiency. To this end, we propose a novel linker competitive coordination strategy based on the electronegativity difference of two kinds of organic linkers to tailor the porous structure of Ti-MOF (MIL-125). A series of Ti-MOFs with continuously tunable hierarchical porosity is obtained by simply adjusting the molar ratios of two organic linkers. The demonstration of toluene removal shows that the competitive coordination strategy not only contributes to wide pore size distribution to enhance adsorption performance of toluene, but also endows good charge separation ability to facilitate photocatalytic performance. This strategy opens a new prospect to optimize Ti-MOF properties for various heterogeneous catalysis applications. |
