Preparation of Titanium Dioxide Nanotube Arrays and Photocatalytic Degradation of Methyl Orange

Abstract:

This paper adopted electrochemistry anodic oxidation method for preparing TiO₂ nanotube array membrane on a pure titanium sheet. The results showed that TiO₂ nanotube arrays were regularly obtained when anodizing voltage at 25V, anodizing time in 60min , NH₄F concentration at 0.25mol·L^-1, and volume ratio of glycerol and water at 2:1. Using of this titanium dioxide nanotube array photocatalyst, and Under light of ultraviolet lamp, the photocatalytic degradation of methyl orange solution was studied in this paper. The main factors affecting the test selection was: the concentration of methyl orange solution (5mg·L^-1, 10mg·L^-1, 15mg·L^-1, 25mg·L^-1, 35mg·L^-1), pH of methyl orange solution (2.0,2.5,3.0,3.5, 4.0,5.0,5.5,6.0), catalytic time (30min.60min, 90min, 120min, 150min, 180min, 240min), UV light source (6w, 11w, 15w).
