二氧化钛纳米管阵列制备及其对甲基橙的降解应用
Preparation of Titanium Dioxide Nanotube Arrays and Its Application in the Degradation of Organic Dyes
摘要
Abstract
Objective]To develop a new type of titanium dioxide (TiO2) photocatalyst for the degradation of organic pollutants.[Method] Tita-nium based titanium dioxide (TiO2) nanotube arrays were prepared by electrochemical oxidation method,and their microstructures were charac-terized,degradation of methyl orange was used to investigate the sintering temperature ,initial dye concentration and the effect of pH on the catalyt-ic performance of TiO2 nanotube arrays.[Result] The results showed that TiO2 nanotube arrays prepared by sintering temperature at 500 ℃had good morphology and the highest photocatatytic degradation efficiency; The efficiency of dye degradation with higher initial concentration was higher than that of low concentration by TiO 2 nanotube arrays;The degradation efficiency of methyl orange solution of pH 3 was higher than that of pH 5.77 by TiO2 nanotube arrays.The degradation efficiency of methyl orange solution of 10 mg/L (pH 3) by TiO2 nanotube arrays (500 ℃) in 60 minutes could reach 85.2%.[Conclusion] The effective photocatalytic degradation of organic dye by the TiO2 nanotube arrays made in this paper has broad application prospects in the field of dye wastewater decolorization and so on .关键词
