Experimental design of Fe3O4@C nanoparticles preparation and their adsorption properties
The cultivation of skills in experimental practice is an important component of applied un-dergraduate teaching,and experimental safety is the basis of experiment.Fe3O4@C nanoparticles with core-shell structure were prepared by solvothermal method.The phase structure and morphology of nanoparticles were characterized,and its adsorption properties for hexavalent chromium were studied.By using high-pressure reactors to prepare materials,students can strengthen further awareness of la-boratory safety and the standardization of experimental operations.Through a series of comprehensive experimental teaching of material characterization and performance research,students can further strengthen their understanding and learning of materials discipline,cultivate their scientific research a-bility and comprehensive analysis ability,and promote their awareness of environmental protection and innovation.
