Abstract
The nano-sized ZnFe2O4 films were prepared by Sol-gel process on the conducting electricity glass, and the influence factors of the samples’ photoelectron-catalytic performances was investigated, such as the pole materials, the distance between electrodes, the voltage and the light source etc. The results indicated that, the photoelectron-catalytic effect was best when ZnFe2O4 film as the anode and the conductive glass as the cathode, which showed that the main reaction was the photo-generated holes. When the voltage was constant, there was an optimal value of plate spacing. With the plate distance increasing, the effective contact probability of the photon-generated carrier and the degradation was increased. But the plate spacing was too wider, the moving resistance of photon-generated carrier became higher, so as to the degradation rate decreased. The degradation rates of the films showed undulate increase with the voltage increasing in the different kinds light resources conditions.
