Zhao Jincai is a Chinese environmental chemist and researcher of Institute of Chemistry of the Chinese Academy of Sciences. In 2011 he was elected as an academician of CAS. His research mainly focuses on photocatalytic degradation of toxic and persistent organic pollutants. Zhao introduced TiO
2-based photocatalyst under visible light, and discovered new functions of molecular oxygen in photocatalysis.[1]

Research

In 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 (Fe2+ 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 [FeIII(PcS)] can result in electron transfer from ligand(L) to Fe3+, then Fe3+ can be reduced to Fe2+. The Fe2+-L complex can react with H
2O
2 to produce HO., leading to the degration of pollutants.[2][3]
