采用过渡金属Cu和稀土金属Ce对TiO2进行改性。运用正交实验设计TiO2的改性方案。以Cu-Ce掺杂负载量、Cu-Ce摩尔比和烧结温度为正交实验设计因子,以光催化甲醛溶液的降解效率为目标因子,编制正交设计表。同时运用多元非线性回归模型,建立多元非线性拟合数学关系方程。结果表明,将正交实验设计方法与多元非线性回归模型相结合,不仅可以弥补正交实验设计的不足,提高实验设计的可靠性,而且实现对各实验各影响因素由定性分析向定量分析转变,有利于高性能纳米光催化材料的制备与性能分析。
The use of transition metal Cu and rare earth Ce modified TiO2. Orthogonal experiment design TiO2 modification scheme. The orthogonal design table was prepared by taking Cu-Ce doping amount, molar ratio of Cu-Ce and sintering temperature as orthogonal experimental design factors, and taking degradation efficiency of photocatalytic formaldehyde solution as the target factor. At the same time using multiple nonlinear regression model, the establishment of multiple nonlinear fitting mathematical relationship equation. The results show that the combination of orthogonal experimental design method and multivariate nonlinear regression model can not only make up for the lack of orthogonal experimental design, improve the reliability of experimental design, but also to achieve a qualitative analysis of each experimental factors to quantitative analysis of the change , Is conducive to the preparation and performance analysis of high-performance nano-photocatalytic materials.
