Preparation of TiO2-activated carbon complex membranes and their photoelectrocatalytic activity
The experimental process of preparing TiO2-activated carbon complex membranes with activated carbon powder as main carrier, PTFE as binder and wire netting as matrix is described in detail, and both photo-catalysis and photo-electro-catalysis are measured to study the properties of complex membranes. Experimental results show that the photo-catalytic activity of the membranes is high and stable in the process of treating Rhodamine-B; the application of an electric field accelerates the speed of photo-catalysis, and the efficiency of photo-catalysis is increased 2.5 times when the applied voltage is 0.8 V; and the degradation of Rhodamine-B follows the dynamics of first order reaction. It is concluded from the discussion of experimental results that the preparation process of TiO2-activated carbon complex membranes is a simple low-cost process suitable for large scale application.
