Silvery Grey Material Zirconium Wire

Carbon-coated nanoparticles were prepared by electroblasting of wires in organic liquids. With anhydrous ethanol as the medium, a high-voltage pulse current is applied to the high-purity zirconium wire, and the zirconium wire is rapidly melted, gasified, expanded and exploded under high-density current, and the carbon-coated ZrC nano-powder particles are prepared with the precipitation of carbon in ethanol and the reaction and coating process of carbon and zirconium under high temperature and high pressure.

1.UIO-66-NH_2 was synthesized by electrochemical method with metal zirconium wire as the metal source, 2-aminoterephthalic acid as the organic ligand, tetrabutylammonium bromide as the conductive salt, and N,N-dimethylformamide and regulator as the solvent by applying an external voltage. In the experiment, a series of products were obtained by changing the solvent ratio, reaction voltage and reaction time, and the obtained products were characterized by XRD diffraction and SEM, and the structure and morphology of the materials under different reaction conditions were analyzed. When the volume ratio of N,N-dimethylformamide to acetic acid was 52:8, the applied DC voltage was 4 V, and the synthesis time was 1 h, the obtained UIO-66-NH_2 material had high crystallinity and uniform spherical morphology.
