摘要
以碘氧化铋和硅藻土为原料,采用直接超声水解负载合成的方法制备了负载碘氧化铋硅藻泥和功能性活性组分。同时模拟研究在室内环境条件下,采用该活性组分硅藻泥对室内空气中甲醛的吸附光催化净化效果进行了检验。实验结果表明,在室温和相对湿度为75%的条件下,制备的样品对甲醛有较好的净化效果,7 h对甲醛的净化率达到53. 17%,且衰减率只有8%。
Bismuth oxyiodide is a new photocatalytic material with better formaldehyde photocatalytic degradation than titanium dioxide.By loading bismuth oxyiodide over diatomite,the photocatalytic material that had high potential application for formaldehy purif icatory was obtained.Diatom mud was synthesized by using diatomite loaded with bismuth oxyiodideas photocatalytic material,and its removal on formaldehyde in indoor air and purification persistence were discussed.The result showed that diatom mud had an excellent capacity for formaldehyde purification under the condition of ambient temperature and relative humidity of 75%.In this condition,its purification efficiency of formaldehydethe reached to 53.17% and its attenuation rate was only 8% in 7 h.
