Abstract: “The photocatalyst nano-ZnO powder was fixed on organic supports to overcome drawbacks of photocatalyst powder used in aqueous phase as difficulty of recovery and reutilization. Although photocatalyst surface area fixed on supports was resulted in decline of photocatalytic efficiency, sorption capacity of the organic supports (silicone, ABS, epoxy, polybutadiene) expected that photocatalytic efficiency was maximized through synergistic effect both the sorption capacity of organic support and phtocatalystic mechanism of ZnO. The NZOC (Nano-ZnO/Organic Composites) was manufactured according to physical and chemical combination method. Before manufacturing NZOC, the raw organic supports were evaluated about sorption capacity of TCE, which is representative nondegradable organic material. Also, the developed NZOC was evaluated about 1) water resistance tests, and 2) photocatalytic removal efficiency tests of TCE. In the results of experiment, ABS resin was observed similarly with efficiency”
