Outline of Final Research Achievements

To reduce the risk of infection diseases existing in the living environment, the materials with high antiviral activity were investigated. The antiviral activity of seven metal oxides was evaluated using bacteriophage, and it was revealed that MoO3 has high antiviral activity. In addition, I prepared a new visible-light-sensitive photocatalytic material, utilizing the high antiviral activity of MoO3, and it was shown that a material (Mo/TiO2) which combines titanium oxide and molybdenum oxide has highly antiviral activity under visible light irradiation.

Academic Significance and Societal Importance of the Research Achievements

銅や銀などのイオンの抗菌・抗ウイルス活性については、多くの知見があるが、水に不溶の固体金属酸化物の抗ウイルス活性についての知見は、これまでにあまりなく、モリブデン酸化物に高い抗ウイルス活性があることを新たに見出した。また、モリブデン酸化物を使った新規の可視光応答型光触媒を作製できたことも、新規性が高い。さらに、新型コロナウイルスによる感染症が問題となっている社会に対して、新しい材料の提案ができた点においても、意義深いと考えられる。
