| Research Abstract |
We have investigated following subjects.
1. Development of new functional (intelligent) materials by combining photochemistry and electrochemistry : An example of our achievement is our recent discovery of LB (Langmuir-Blodgett) film that responds differently to light and to electrode potential. We have proposed the possibility of development a superhigh density recording device with this material. Another example is our success in developing a new display device by based on electrochromic reactions. We have also found a new type of diamond thin film can be obtained by pretreating the substrate using photoelectrochemical techniques.
2. Environment and photoelectrochemistry : The charge separation at the interface in a heterogeneous system was utilized. Utilization of light energy to induce chemical reactions was our main concern. The (photo) electrochemical approaches are actively pursued for the production of hydrogen, a clean energy source, and the efficient reduction of carbon dioxide, a substance maligned as the source of global warming. In addition, attempts are being made recently for the use of new deodorizing and contamination-proofing photocatalytic materials prepared by coating thin films of semiconductor materials on various types of substrates.
