Electroless Plated Ni-P/TiO_2 composite films were deposited from an acidic solution or an alkaline solution containing photocatalytic TiO_2 particles (P-25). The dispersion of particles in the films was investigated by the cross-sectional observation with a transmission electron microscope. The particle content in the films increased with an increase of its amount in the solutions. The deposition rate of composite films was independent of the amount of TiO_2 particles in the solutions(0 〜 100 g dm^<-3>). Photocurrent density of the films in 0.1 M NaOH aqueous solution rose with particle content in the films.

从酸性溶液或含有光催化TIO_2颗粒的酒精溶液（P-25）中沉积电镀元的Ni-P/TIO_2复合膜。通过带有透射电子显微镜的横截面观察研究了膜中颗粒的分散。膜中的粒子含量随溶液中的量增加而增加。复合膜的沉积速率与溶液中TIO_2颗粒的量无关（0至100 g dm^<-3>）。 0.1 M NaOH水溶液中膜的光电流密度在膜中具有颗粒含量。
