中文摘要： 本项目依据分子工程学原理，拟采用溶剂扩散法，自组装法，水热或溶剂热等方法，将卟啉或金属卟啉、金属氧簇、第二配体共组装构筑具有特定结构和功能性质的金属-有机骨架化合物(MOFs)。MOFs的孔结构能有效促进催化反应的选择性和效率，卟啉及其衍生物的光吸收特性有助于拓宽MOFs材料的光谱响应范围，二者的有机结合可为设计和制备性能优异的光催化材料提供新的生长点。通过对各种合成因素（前驱体的选择、反应物配比、合成方法、实验条件控制等）的考察、催化剂结构组成的表征及初步光催化降解实验，揭示催化剂结构和性能之间的关系，优化催化剂制备方法，以获得具有高效催化活性的MOFs光催化剂。以PPCPs类化合物为目标污染物，系统研究拟制备催化剂的光催化活性、污染物的光降解动力学和反应机理，为该类污染物的无害化处理提供新技术。

英文摘要： In this project, we will use solvent diffusion method, self-assembly method, hydrothermal or solvothermal methods, etc. and choose porphyrin or metal porphyrin and metal oxygen cluster under the presence of the second ligands on the basis of molecular engineering principle to build metal-organic frameworks (MOFs) compounds with specific structure and functional properties. The porous structure of MOFs can effectively improve catalytic reaction selectivity and efficiency, and the photoabsorption characteristics of porphyrin and its derivatives will also help broaden MOFs material spectral response range. Hence, their combination in a system will be new growing point for designing and preparing photocatalysts with superior performance. In order to reveal the relationship between the catalyst structure and performance and then optimize the preparation methods to achieve the high active MOFs photocatalyst, various factors such as precursor types, raw material ratio, synthetic method, experiment conditions and so on, will be test during the process of catalyst preparation, and the various characterization techniques will be conduct and as well as preliminary experiment of photocatalytic degradation. Using PPCPs compounds as model pollutions, the photocatalytic activity of as-prepared catalyst and the kinetics of phot
