| Outline of Final Research Achievements |
Photocatalytic water-splitting is an ideal method for solar energy harvesting. Some photocatalysts that can split water under UV light have been discovered. However, development of visible-light sensitive photocatalysts is indispensable due to the effective utilization of incoming solar energy. On the other hand, semiconducting iron disilicide (β-FeSi2) has a band gap of approximately 0.80 eV and a very large optical absorption coefficient over 1E5 /cm at 1 eV.
In this report, we report on the novel fabrication method of β-FeSi2/3C-SiC composite powder by using metal-organic chemical vapor deposition (MOCVD) method which is general in semiconductor process technology. This β-FeSi2/SiC composite powder could evolve hydrogen (H2) from methyl-alcohol aqueous solution under irradiation of visible light with wavelengths of 420-650 nm.
