The physical and chemical states of zeolite-supported TiO2 were evaluated via powder X-ray diffraction(XRD),Fourier transform infrared(FTIR)and nitrogen adsorptionedesorption isotherms.The effects of operational parameters,including TiO2 content,
calcination temperature,pH,initial dye concentration,as well as catalyst dosage,on photocatalytic degradation performance were examined.The photocatalytic reaction followed first-order kinetics for all catalysts;optimum photodegradation efficiency was found to result from the use of a high TiO2 concentration (20%TiO2),a calcination temperature of 600 C,alkaline pH(9e10)and a catalyst dosage of 5333 ppm.

天然生成的二氧化钛的物理和化学状态是通过X射线粉末衍射,红外线傅立叶变换和氮吸附解吸等温线的方法确定的。工作参数的作用,包括二氧化钛的含量,
煅烧温度,pH值,初始染集中和催化剂剂量,在光催化的降解过程中被检验了。
光催化反应跟随着所有催化剂的一级动力学反应;我们通过用20%浓度的二氧化钛(煅烧温度600摄氏度,呈碱性pH值,催化剂量5333ppm)找到了适度的光降解率

有点吃力了。。。。好多说法都不懂。。
