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.

我们调查了以下课题： 1．通过结合光化学和电化学来开发新型功能（智能）材料：我们的成就的一个例子是我们最近发现的 LB (Langmuir-Blodgett) 薄膜，它对光和电极电势有不同的响应。我们提出了用这种材料开发超高密度记录设备的可能性。另一个例子是我们成功开发了一种基于电致变色反应的新型显示设备。我们还发现利用光电化学技术对基底进行预处理可以获得一种新型的金刚石薄膜。 2．环境和光电化学：利用异质系统中界面处的电荷分离。利用光能引发化学反应是我们主要关注的问题。 （照片）电化学方法被积极用于生产氢气（一种清洁能源）和有效减少二氧化碳（一种被诟病为全球变暖的根源的物质）。此外，最近正在尝试使用通过在各种类型的基底上涂覆半导体材料薄膜而制备的新型除臭和防污染光催化材料。
