Prof. Hongxian Han is group leader of DNL1602。. Currently, he is a research Scientist in the State Key Laboratory of Catalysis, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and Division of Solar Energy Research, Dalian National Laboratory for Clean Energy. He received the Hundred-Talent-Program of the Chinese Academy of Sciences in 2009 and priority support in 2011. After PhD study in the University of New South Wales, Sydney, Australia, he went to USA and worked as postdoctoral research fellow/project research scientist in the University of Nebraska-Lincoln(postdoctoral fellow), and Lawrence Berkeley National Laboratory (postdoctoral fellow/project research scientist) . His main research experience lies in: fullerene, charge transfer complexes of TTFs and derivatives, photoinduced charge transfer in heterogeneous media and long lived charge separated state, high spin organic polyradicals for magnets, photocatalytic splitting of water and photocatalytic reduction of CO2.

Currently at DICP, Prof. Hongxian Han focuses his research field on solar energy to chemical energy conversion, including four reactions: hydrogen production via photocatalytic reforming of biomass, and hydrogen production via photocataltyic degradation of industrial wastes. hydrogen production via photocatalytic splitting of water, photocatalytic reduction of CO2,

Representative Research Outcomes

1) ZnO and ZnGeON can form a kind of solid solution phase junctions, which is assemble to the electron transfer chain in natural photosynthesis. Formation of such kind of solid solution phase junction can facilitate the charge transfer and separation, enhancing the photocatalytic activity (J. Phys. Chem. C, (2010), 114, 12818-12822). 2) Development of a new methodology for the assembly of visible light absorbing MMCT electron pump unit on the surface of mesoporous materials, such as MCM-41 (Microporous and Mesoporous Mater, (2007), 103, 265-272，J. Phys. Chem. C, (2008), 112, 16156–16159). 3) TiOCr electron pump coupled to IrOx multi-electron transfer catalyst can oxidize water under visible light irradiation with quantum efficiency of 13 % (J. Phys. Chem. C, (2008), 112, 8391-8399). 4) Photocataltyic reduction of CO2 to CO on Ti-MCM41under UV light irradiation, and observation of O2 evolution for the first time. The mechanic study shows that the photoreduced CO formation is two photons one electron transfer process (J. Phys. Chem. B, (2004), 108(47), 18269-18273). 5) Determined the redox potential of Al-MCM41; thermodynamic study shows that the long lived radical species formed upon irradiation of D-B-A triads are either the D+• or A-• radicals through electron transfer between the redox sites of Al-MCM41and the D or A moieties of the D-B-A (Res. Chem. Intermed. , 34 (5-7), 551-564, 2008).
