个人简介

Prof. Xu obtained BS from Beijing University (1996), MS from University of Michigan at Ann Arbor (1998), and Ph.D. from Cornell University (2001). He was a postdoc with David B. Mitzi at IBM T. J. Watson Research Center from 2001-2003. Prior to moving his research program to CityU, Prof. Xu was an assistant professor at the George Washington University from 2003 to 2005. Prof. Xu has been awarded the PRF Starter Grant from the American Chemical Society (2004), and he was a winner of the ORAU Ralph E. Powe Junior Faculty Enhancement Award in 2004. He is also a recipient of the Humboldt Research Fellowship for Experienced Researchers (host: Prof. Markus Antonietti, MPI of Colloids and Interfaces, Potsdam), 2011-2013. Since joining CityU in 2005, Xu has attracted nine major research grants from the Research Grant Council (the Hong Kong equivalent of the NSF in the United States) totaling over 5,000,000 HK$.

研究领域

Zhengtao Xu’s group closely integrates molecular synthesis and the study of porous framework materials (MOF, COF and open cage compounds) for versatile sensing, separation, catalysis and electronic applications. We realize that, the extremely powerful molecular synthetic methods of modern chemistry, once mobilized in the study of open framework systems, is bound to open up broad areas of research in materials science. For example, our long-standing pursuit across framework engineering and organic synthesis has opened up the field of sulfur-equipped porous frameworks (SPF), wherein the powerful sulfur functions are starting to usher in a broad horizon of research in catalysis, semiconductors, sensors, heavy metal removal, energy storage and proton conductivity.
