Abstract


Graphene is a newly discovered carbon nanomaterials , large surface area , the preparation process is simple , has a unique physical and chemical properties , has become a new hot spot in the field of nanotechnology research has great potential , especially in water treatment . By a redox Preparation of graphene and graphene load metal ( Graphene - Pt graphite oxide as a starting point , the the Graphene - Cu ) and metal oxide ( Graphene - of Fe 3 < / sub > O 4 < / sub>, Graphene-MnO 2 ) nano-materials , and as a catalyst selected endocrine disruptors 2,4 - dichlorophenol degradation of catalytic ozonation . Graphite oxide were prepared , according to the type of load characteristics of the precursor , the type of metal and metal oxide load graphene - platinum the graphene - copper graphene -Fe 3 < / sub > O < sub > 4 < / Sub > and graphene -MnO2 materials. By X-ray powder diffraction , Raman spectroscopy , X -ray photoelectron spectroscopy , thermal gravimetric analysis , atomic force microscopy , transmission electron microscopy and other modern testing equipment and methods of sample structure and morphology characterization . Catalytic degradation of performance studies have shown that 6.4 wt % graphene - platinum materials and graphene - Fe of < / sub > O 4 < / sub > do catalyst the catalytic ozonation ability and higher than the graphene Description graphene and metal platinum or Fe 3 O 4 combination of catalytic ozone decomposition synergy . The degradation of the performance tests showed that under the same conditions , the type of the initial concentration of the degradation rate of the type , the faster the lower the concentration of the removal . Different pH conditions also affect the removal rate of removal under neutral conditions . The graphene load copper catalyst removal of 2,4 - dichloro- phenol removal Graphene generally basically the same. Graphene - the catalytic ozonation ability of the porous MnO2 material graphene , has a negative catalytic effect .
