Synthesis Of Iron Oxide/Cobalt Oxide/Carbonaceous Nano Material And Their Application In The Environmental Manipulation

The study take glucose as carbon source, carbonaceous microspheres was synthesized by the hydrothermal method. The surface morphology and structure of the carbon nanometer microsphere were characterized by XRD, SEM, EDS, UV-Vis, BET and FT-IR. And research the adsorption performance of the sample for Cr (VI), phenol and RhB. The results show that the adsorption of carbonaceous microspheres for Cr (VI) and phenol, RhB from aqueous solutions of the optimal pH value is2.0,4.0, and4.0, respectively. The kinetic studies indicated that the adsorption process was best described by the pseudo-second-order kinetics. The Freundlich model fitted our experimental data better than the Langmuir model.CO3O4nanoparticles were prepared by hydrothermal synthesis using Co (NO3)2as cobalt source. The surface morphology and structure of nanometer CO3O4were characterized by XRD, SEM, EDS, UV-Vis, TEM, and HRTEM. And research the catalysis performance of the sample for phenol. The results indicate that by adding1.2mL of H2O2prepared CO3O4catalytic effect best, reaction after7h, phenol degradation rate nearly100%.Nanometer Fe2O3were prepared by co precipitation method and high temperature burning. The surface morphology and structure of nanometer Fe2O3were characterized by XRD, SEM, UV-Vis, TEM, and HRTEM. And research the catalysis performance of the sample for phenol and RhB. The results showed a-Fe2O3nanoparticles for the degradation of phenol and RhB rate were84%and91%, respectively. Nano γ-Fe2O3for the degradation of phenol and RhB rate were73%and91%, respectively.Nanometer Fe3O4were prepared by means of co precipitation. The surface morphology and structure of nanometer Fe3O4were characterized by XRD, SEM, and UV-Vis, TEM, and HRTEM. And research the catalysis performance of the sample for phenol and MB. The results showed that blending10%Co Fe3O4nanoparticles on phenol degradation rate of close to97%.Mixing13%of Co nanoparticles of MB degradation rate close to100%.
