Center for Air Pollution Control Technology

Dr. Hong He is a Professor of the Research Center for Eco-Environmental Sciences (RCEES), Chinese Academy of Sciences, and is the winner of the NSFC “Distinguished Young Scientist”. Dr. He received his doctorate (Ph.D) from the University of Tokyo in 1994. He studied and worked for 11 years in Japan, the United States and Canada, and thereafter joined RCEES through the “100 Talents Program” of Chinese Academy of Sciences in 2001. His research has mainly focused on fundamental and applied research in environmental catalysis and heterogeneous atmospheric chemistry, and has made numerous and substantial achievements in the areas of diesel emission control technologies, catalytic indoor air purification and the mechanism of haze formation.Dr. He has published 215 papers as the first author or corresponding author in peer- reviewed journals, of which 191 papers are indexed by SCI, with over 5000 citations. He has also published a scholarly book (The Principles and Application of Environmental Catalysis) in Chinese and two chapters in related English books. Thirty three patents have been granted with Dr. He as first author, seven of which have been applied commercially. He won the National Technology Invention Award (Second Prize) in 2011 and the National Science and Technology Progress Award (Second Prize) in 2014. He is also the project leader of the National 863 project “Key technologies and system for the emission control of diesel vehicles” and the chief scientist of the Strategic Priority Research Program of CAS (Category B) “Formation mechanism and control strategies of haze in China”.

Effect of Fe on the photocatalytic removal of NOx over visible light responsive Fe/TiO2 catalysts

Jinzhu Ma,Hong He*,Fudong Liu

We synthesized different Fe/TiO2 catalysts and studied the influence of Fe on the structure and performance of Fe/TiO2 as a photocatalyst to remove gaseous NOx in air under visible light. The electron paramagnetic resonance results revealed that Fe ions substituted the Ti ions of TiO2 prepared by co-precipitation, which extended the visible light absorption and promoted the separation of electron–hole pairs, and hence promoted the activity of the catalysts. No Fe ions were incorporated into the crystal lattice of TiO2 prepared by conventional wet impregnation method. Characterization and Density functional theory calculations indicated that the substitution of Fe atom for Ti atoms lead to a narrowing of the band gap. The Fe 3d states were located at the bottom of the CB and partially overlapped with the energy band of TiO2, as shallow donor energy levels. Fe doping also induced an acceptor state at the top of the VB as shallow acceptor energy levels, which was caused by hybridization between the Fe3d, O 2p and Ti 3d states. Therefore, these impurity states prolonged the lifetimes of photoexcited carriers and enhanced photocatalytic performance. These findings would be of help in designing photocatalytic with high performance under visible light.
