Method for preparing titanium dioxide photocatalyst dopped silver and photocatalyst prepared thereby |
| abstract |
The present invention provides a method of preparing a silver-doped titanium dioxide photocatalyst comprising the steps of: (a) using a titanium precursor to prepare titanium dioxide; (b) preparing a mixture solution containing titanium dioxide prepared in the step (a), a silver precursor and an alkaline material; (c) irradiating the mixture solution with UV rays to prepare a silver-doped titanium dioxide; and (d) annealing the silver-doped titanium dioxide. According to the present invention, by adding the alkaline material to the mixture solution containing titanium dioxide and the silver precursor for photodeposition, the surfaces of titanium dioxide particles can be uniformly doped with silver, thus increasing the separation efficiency of electron(e^-)-hole(h^+) pairs (EHP) and lowering the activation energy required for photo-excitation. Therefore, the method can produce a titanium dioxide photocatalyst which shows excellent photo-reaction characteristics in the visible and ultraviolet ranges. |
