碳掺杂TiO2光催化剂的制备及其性能表征
Preparation and Characterization of Carbon-doped TiO2 Photocatalyst
摘要
Abstract
Glucose and tetrabutyl titanate were used as precursors, the photocatalyst C-TiO2 was successfully prepared by alcoholysis at room temperature. The effects of calcination temperature, catalyst dosage and initial pH of reaction solution were evaluated by the photocatalytic activity of degradation reactive brilliant red X-3B. The catalysts were characterized by X-ray diffraction (XRD) ,UV-Vis diffuse reflectance spectra (UV-Vis DRS) ,ther-mogravimetric analysis (TG-DTG) and scanning electron microscopy (SEM-EDS). The results showed that the C-doped TiO2 has the typical anatase structure and satisfied photo-catalytic efficiency on the degradation of reactive brilliant red X-3B under visible light. While the dosage of catalyst 1. 5 g · L-1, pH value 7~9> calcination temperature at 500 °C, visible light irradiation for two hours, the photocatalytic degradation of concentration is 100 mg · L-1 reactive brilliant red X-3B could reach above 70%.关键词
