摘要

利用利用利用替代方法合成磷(P-TiO2)合成磷(son)对纳米光质活性增加的影响。本研究的目的是确定P-TiO2中增加磷剂量的速率对颗粒大小和光质活动的影响。最初使用的成分是tween、异丙基酒精、钛异丙唑(TTIP)和H3PO4,比11毫升:60毫升:7毫升:0.2毫升0.2 ml /小时;0,13毫升/小时;每小时0.1毫升搅拌24小时。温度的P-TiO2 dikalsinasi 450˚C,然后dikarakterisasi用TEM分析P-TiO2粒子的大小和试验用远UV-Vis知道fotokatalisnya活动。描述TEM结果粒度样品P-TiO2兴奋剂速度增加0.2 ml /小时(为9.8±1.4万)nm。根据UV-Vis光谱仪的测试,磷兴奋剂增加的速率对P-TiO2光谱仪活动的增加没有显著影响。但是在P-TiO2样本中,以每小时0.2毫克的剂量增加的速度,光质活动增加了一点。关键词:服用荧光粉、光催化剂、纳米粒子、黄藻、凝胶。我认为这项研究的目的是确定增长率和增长率之间的效果。这个研究中使用的生材料是10月80日、异丙醇、钛异丙酚(TTIP)和H3PO4与11毫升的含量:60毫升:7毫升:0.2毫升。0.2 ml /小时;0,13毫升/小时;每小时0.1毫升。P-TiO2是calcined at 450˚C,然后用传输电子Microscopy characterized by (TEM) to analyze P-TiO2之粒子大小和UV-Vis spectrophotometer到《absorbance个重大价值。TEM characterization之results:用imageJ软件那里那个粒子大小的P-TiO2样品是(9.8±1.4)nm。基于UV-Vis光谱仪的结果,磷的增量增加没有意义差异的照相活动。However,一个以0.2毫升/小时为单位的样本,这种增加的照相活动越来越高。小脑:纳米粒子,磷酸盐,照相质,黄绿色。二世
