AI Technical Summary

Technical Problem

Existing catalysts suffer from low catalytic activity and cannot be reused. In particular, immobilized catalysts are prone to deformation and breakage during stirring, and uneven contact with the solution leads to reduced catalytic efficiency.

Method used

The Co@NC-CNT/DME catalyst preparation method involves preparing CNTs/DME precursors, ZIF-67-CNTs/DME, Co@CN-CNTs/DME, and PDA modification to form a PDA-modified Co@CN-CNTs/DME immobilized catalyst. A recyclable stirring device, including a mounting plate, a central shaft, and a water flow dispersion plate, is used to prevent the catalyst from deforming and breaking during the stirring process.

Benefits of technology

This approach enables the reuse of catalysts, reduces the amount of Co ion leaching, improves the dispersion and catalytic activity of catalytic active sites, enhances the stability and durability of catalysts, and improves the efficiency of catalytic reactions.
