Characterization of Metal (Cu, Zn)-Carbon/TiO2 Composites Derived from Phenol Resin and their Photocataytic Effects

다국어 초록 (Multilingual Abstract)

Metal-carbon/TiO2 composite photocatalysts were thermally synthesized through the mixing of anatase to metal (Cu, Zn) containing
phenol resin in an ethanol solvent coagulation method. The BET surface area increases, with the increase depending on
the amount of metal salt used. From SEM images, metal components and carbon derived from phenol resin that contains metal
was homogeneously distributed to composite particles with porosity. XRD patterns revealed that metal and titanium dioxide
phase can be identified for metal-carbon/TiO2 composites, however, the diffraction peaks of carbon were not observed due to the
low carbon content on the TiO2 surfaces and due to the low crystallinity of the amorphous carbon. The results of a chemical elemental
analysis of the metal-carbon/TiO2 composites showed that most of the spectra for these samples gave stronger peaks for
C, O, treated metal components and Ti metal compared to that of any other elements. According to photocatalytic results, the MB
degradation can be attributed to the three types of synergetic effect: photocatalysis, adsorptivity and electron transfer, according
to the light absorption between the supporter TiO2, metal species, and carbon layers.
