1968 Fujishima Akira, the graduate student from Engineering school of University of Tokyo, discovered the mysterious Photocatalyst features of semiconductor TiO2. 日本東京大學大學院工學系研究科學生藤嶋昭發現二氧化鈦光觸媒的特性。
1971 Fujishima Akira earned PhD degree, served as a lecturer in the Faculty of Engineering of Kanagawa University. 藤嶋昭取得博士學位，至神奈川大學工學部擔任講師。
1972 Fujishima Akira delivered the academic paper on Photocatalytic property of TiO2. His findings suggested that light energy can be transformed into chemical energy through specific mechanism. In the age of global energy crisis, his research proposed an alternative energy source and thus drew attention of researchers around the world. His discovery was even referred as “Fujishima Effect”. The following studies yet showed that Photocatalyst can not process materials in a large amount, so it was not applied for the development of novel energy source for a period of time since then. 藤嶋昭將其關於二氧化鈦光觸媒的研究結果撰寫成論文發表。因該發現表示「光能可以透過某種機制轉換為化學能」，在正值全球石油危機、對新能源開發有急切需求的時代背景下，其研究似乎為此指出新的路徑，因而引起全球各界學者的注意，其發現並被命名為「藤嶋效應」（Fujishima Effect）。然而此後的研究顯示，光觸媒並不適合用於一次處理大量物質，因此此後相當時間裡都未被應用於新能源的開發。
1975 Fujishima Akira went back to the Faculty of Engineering at University of Tokyo as a lecturer. His main research area was still on Photocatalyst. 藤嶋昭回到母校東京大學工學部任講師，仍以光觸媒為主要研究領域。
