微乳液制备粉煤灰微珠负载型La3+ 、Fe3+共掺杂TiO2光催化剂
Preparation of supported Fe3+, La3+-doped TiO2 photo catalyst by micro-emulsion reaction
摘要
Abstract
With fly ash as a carrier, La3+, Fe3+co-doped TiO2 photo catalyst was prepared by micro-emulsion. The appearance of composite particles was observed by transmission electron microscopy and scanning electron microscopy. The component of the composite particles which have been calcined was analyzed by X-ray diffraction. The TiO2 covered degree of fly ash and its photo catalyst degradation of methly orange were measured by spectrophotometer. The results showed that La 3+, Fe3+co-doped TiO2/ fly ash had a well-distributed size and a good dispersion degree. The covered degree of TiO2 was 35.67%. The degradation of methly orange was 48%. The regeneration of TiO2 was five times. The synergistic effect of Fe3+, La3+ increased the activity of the photo catalyst when Fe3+ -doped was 0.3% and the La3+ -doped was 1.0%.关键词
