Lanthanum doping TiO2 were prepared by sol-gel method, an the photocatalytic degradation experiments were performed by using methyl orange solution as a target degradant. The results indicated that Suitable doping quantity of lanthanum can improve the photocatalytic activity of nanometer TiO2 powders. On the basis of 50 mL methyl orange solution what concentration is 20 mg/L, photocatalytic activity is the best when doping quantity of lanthanum were 1.0 wt %. Through the relatively experiments by using sunshine and ultraviolet as light source, the results indicated that the La3+ doping broaden the scope of visible light area what TiO2 response to.

Degradation Of Methyl Orange

This paper adopted electrochemistry anodic oxidation method for preparing TiO2nanotube array membrane on a pure titanium sheet. The results showed that TiO2nanotube 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).
