We performed a trial of experiments using photocatalytic reaction in advanced course in college of technology. Using titania, the following experiments were carried out ; decomposition of methylene blue solution, water droplet, fouling and mold preventions. From the results of a student questionnaire, about 90% of the students understood the theory of photocatalytic reaction, about 70-90% were interested in each experiment, and about 80% wanted to utilize the photocatalyst in their daily life. After the experiment, the students investigated the technology and products of the photocatalyst, and also discussed future applications.
