Author(s) Toshihito Ohtake
ABSTRACT
Application of semiconductor particles has been noticed to solve energy problems as photocatalysis for O2 evolution in water splitting etc. We are trying fabrication of semiconductor electrode by n-WO3 particle toward O2 evolution in water splitting. The electrode obtained high photooxidation properties of water as preventing effective recombination between electrons and holes by utilizing fine semiconductor particles. Particularly, application of suspension prepared by ball milling was able to obtain fine n-WO3 thin film and the remarked semiconductor properties.
