摘要

Catalyst Magnetic Montmorillonite NiFe2O4 Materials Science (all) Condensed Matter Physics Mechanics of Materials Mechanical Engineering
By supporting NiFe 2 O 4 onto montmorillonite, the highly active and reusable catalyst for methyl violet oxidation was obtained. By using XRD, TEM, XPS, and VSM analyses, it is obtained that the concentration of precursor was a controlling factor to determine the specific surface area, NiFe 2 O 4 particle size, and magnetism. It is found that adsorption influences the catalytic activity enhancement and the stability of catalysts.
