| Outline of Final Research Achievements |
By using p-type semikonductor CuxO, which can absorb visible-light, as dye and making PN junction with n-type semiconductor TiO2, we have succeeded in preparing high performance visible-light-responsible photocatalyst. The performance is approximately 1.3 times higher than that of MPT-623 (Ishihara-sangyo), which is known as high performance visible-light-responsible photocatalyst. The performance is estimated from a rate of reduction HCOH concentration in flowing air (1 ppm HCOH included) when a white LED on. The spectrum of the LED dose not include any ultra-violet light.
