Multi-defect iron-based MOFs nano-enzyme as well as preparation method and application thereof
The invention provides a multi-defect iron-based MOFs nano-enzyme as well as a preparation method and application thereof, in the process of synthesizing an iron-based MOFs material, a defect ligand which is the same as an original ligand in coordination mode and different in structure is doped, the coordination rate of the defect ligand and a metal node is adjusted through ethidene diamine, directional selective doping of the ligand is realized, a hydrothermal reaction is adopted for 12-24 hours, and the multi-defect iron-based MOFs nano-enzyme is obtained. The iron-based MOFs nano-enzyme material with multiple defects is obtained through subsequent acid treatment and purification, and the obtained material has high POD (peroxidase), CAT (catalase) and SOD (superoxide dismutase) similar enzyme catalytic activity at the same time. As a seed dressing agent, superoxide anions and hydroxyl radicals in crops can be removed, and as a nano-enzyme with good biocompatibility and no toxic or side effect, growth vigor of plant seedlings under salt stress can be improved..
