Zhao Jincai (Chinese: 赵进才; born December 1960) is a Chinese environmental chemist and researcher of the Institute of Chemistry of the Chinese Academy of Sciences. In April 1994, he obtained a doctorate from Meisei University in Japan. In 2011 he was elected as an academician of CAS. He is a professor at the Institute of Chemistry, CAS; Deputy Director of Key Laboratory of Photochemistry; Deputy Director of Science Committee of Molecular Sciences Centre, CAS. His research mainly focuses on the photocatalytic degradation of toxic and persistent organic pollutants. Zhao introduced TiO $_2-based$ photocatalyst under visible light, and discovered a new way for oxygen atom transfer during photocatalytic reactions.

## Research

In the early 2000s, Zhao's group reported that visible light can accelerate the degradation of organic pollutants with aqueous solutions of iron tetrasulfophthalocyanine ([Fe(PcS)]) and H $_2O$ $_2.$ They also found out FeBR $(Fe^{2+}$ complex of 2,2′-bipyridine) is efficient in eliminating organic pollutants such as rhodamine B (RhB), malachite green (MG) and N, N-dimethylaniline (DMA). They did several control experiments, in the dark or under irradiation, with or without irradiation. They proposed that when light is introduced, excitation of $[Fe^{III}(PcS)]$ can result in electron transfer from ligand(L) to $Fe^{3+},$ then $Fe^{3+}$ can be reduced to $Fe^{2+}.$ The $Fe^{2+}-L$ complex can react with H $_2O$ $_2$ to produce $HO^.,$ leading to the degradation of pollutants.

## Contributions

Zhao has published over 200 papers in international journals and obtained 20 Chinese invention patents. Zhao won many awards:

2010 Japanese Photochemistry Association Lectureship Award for Asian and OceanianPhotochemist.

2005 The Second Grade National Prize of Natural Science of China (the first contributor).
