| Abstract: | Titania super fine particle photocatalysts containing dispersed nickel nanosized particles were synthesized. The synthesis method was as follows. First, an W/O type emulsion was made with non-ion surfactant. Titania powder with dispersed nickel oxide or nickel hydroxide was synthesized using a solution of nitric acid, nickel and titanium tetra butoxide (TIB). The titania photocatalyst was formed by reduction caused by heat treatment under a suitable reduction condition. Nickel nano-sized particles were distributed in the titania photocatalysts and the amount of hydrogen generated increased in proportion to the surface area of the distributed nickel. The nickel particles dispersed in titania photocatalysts accelerated the generation of rutile as compared to the photocatalyst without nickel. |
