OP-II-3

PP-III-34preparation (glass fiber fabric) is quite cheap, as well as reagents used for theimpregnation mixture preparation. The technique of the support preparation allowsone to create different shapes of the support in the stage of silicagel hardening.Therefore, the technique of the photocatalyst support preparation described above isshown to be very prospective. The support has been patented [1].The next step of our investigation was studying of the photocatalytic oxidation ofphenol in the batch recirculating reactor with the total volume of the reaction solution3 L. The support with the catalyst was made by the same technique as for theexperiments with DMMP. The tube-shaped support had several layers. The catalyst0.2% Pt/TiO 2 Degussa P25 was used in order to decrease the noble metal amount.The body of the photocatalytic reactor is shown in Fig. 2.Figure 2. Photocatalytic reactor.1 – glass fiber based support with thecatalyst; 2 – UV-lamp; 3 – outer wall;4 – reaction mixture inlet; 5 – reactionmixture outlet.It was shown that the rate of the phenol oxidation on the supported titania is ashigh as in suspended catalyst. Thus, the proposed support is suitable for the scaledupreactors. The development of the new glass fiber based supports allows one tomake the photocatalytic devices cheaper and easier.References[1].
