| dc.description.abstract | Zeolitic imidazolate framework-8 (ZIF-8) was evenly loaded on the surface of TiO<sub>2</sub> doped with KI, using a solvent synthesis method, in order to produce a ZIF-8@TiO<sub>2</sub> (KI) adsorption photocatalyst with good adsorption and photocatalytic properties. The samples were characterized by XRD, SEM, EDX, XPS, BET and UV-Vis. The photocatalytic efficiency of the material was obtained by photocatalytic tests. The results indicate that the doping with I inhibited the grain growth and reduced the crystallite size of TiO<sub>2</sub>, reduced the band gap width and improved the utilization rate for light. TiO<sub>2</sub> (KI) was a single crystal of anatase titanium dioxide. The combination of ZIF-8 and TiO<sub>2</sub> (KI) improved the specific surface area and increased the reaction site. The ZIF-8@TiO<sub>2</sub> (KI) for Congo red was investigated to validate its photocatalytic performance. The optimal concentration of Congo red solution was 30 mg/L, and the amount of catalyst was proportional to the degradation efficiency. The degradation efficiency of ZIF-8@TiO<sub>2</sub> (5%KI) was 76.42%, after being recycled four times. | en |
