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 a preparation method and application thereof. The catalyst materials prepared by the invention are large-particle crystalline Zn-CP (1) materials and nano-graded structure Zn-CP (1a) materials, when catalyzing the conversion of nitro groups into carboxyl groups to synthesize benzoic acid derivatives, and monitored by TLC, the conversion of At the same time, the catalytic reaction uses water as the reaction solvent, which meets the requirements of modern green chemistry. After the reaction is completed, 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 decrease, showing good catalytic activity, and the experiment shows good activity, indicating high catalytic activity and environmental protection. |
