The invention belongs to the field of heterogeneous catalytic materials, and relates to the preparation of crystalline coordination polymers, in particular to zinc coordination polymer catalytic materials and their preparation methods and applications. Catalyst materials prepared by the present invention are large-particle crystalline Zn-CP (1) materials and nanoscale hierarchical structure Zn-CP (1a) materials, when catalyzing nitro groups into carboxyl groups to synthesize benzoic acid derivatives, the conversion is monitored by TLC The yield can reach 100%, and the separation yield can reach more than 84%. At the same time, the catalytic reaction uses water as the reaction solvent, which meets the requirements of modern green chemistry. After the reaction, the catalyst can be recovered by simple centrifugal filtration, and the recovered catalyst can be Continue to catalyze the reaction, and after 20 cycles, the catalytic activity does not decline, showing good catalytic activity. In the experiment, it showed good activity, indicating that it has high catalytic activity and environmental protection. |
