Synthesis and Activity on Modified TiO_2 Coated on Modified Serpentine

摘要

Synthesis method of modified TiO_2 coated on modified serpentine was studied. Synthesized compound material was characterized by SEM, EPMA, and XRD etc. Photocatalytic activities of the obtained samples were examined by degrading tests of simulation phenol wastewater and CN- wastewater. Analysis and test results showes that crystal of TiO_2/ modified serpentine is anatase, material has good photocatalytic activity and regeneration performance. Also, TiO_(2/)modified serpentine photocatalyst has a very good recycling performance. After ten times recycling the photocatalytic degradation rate has been maintained at more than 99%.
