Prof Junwang Tang
Roberts Building
Chemical Engineering
  • Professor of Materials Chemistry and Engineering
  • Dept of Chemical Engineering
  • Faculty of Engineering Science
Prof. Tang obtained his PhD in Physical Chemistry from the State Key Laboratory of Catalysis, Dalian Institute of Chemical Physics, China in 2001. After that, he was appointed as a NIMS researcher and JSPS fellow at the National Institute for Materials Science (NIMS) Japan, working on solar fuels synthesis and photocatalytic organic contaminant decomposition.

In 2005 he moved to the Department of Chemistry, Imperial College London as a senior Research Associate focusing on mechanistic study on  photocatalysis by state of the art time-resolved spectroscoies. In 2009, Dr. Tang joined the Department of Chemical Engineering at UCL as a Lecturer (tenure) and an Honorary Lecturer in the Department of Chemistry, Imperial College London, then promoted to Senior Lecturer, Reader and Full Professor.

Research Summary

  • Selective Photocatalytic Hydrogenation and Oxidation: Mimicking natural green plants, the aim of this project is to activate the small and stable molecules, eg. methane, water, nitrogen and benzene to either renewable and clean fuel or high value chemicals.  The core of the project is the development of efficient inorganic and polymer semiconductor photocatalysts with controllable structures and morphology to facilitate charge separation and utilisation with an aim to manufacture high value chemicals by a green technology operated at ambient condition.
  • Fundamental Understanding of Photocatalysis: Semiconductor development for photocatalyis has to date been largely empirical, with only limited studies of the underlying mechanisms. My group is in parallel undertaking mechanistic studies to explore the basic photochemical processes by time-resolved spectroscopies (eg. transient absorption, scattering spectra, transient IR and Raman spectra etc ), which is fed back to direct material modification for efficient photocatalysis.
  • Functional- & Bio-materials: The research is aimed at utilising the diverse technologies in my group, e.g. sol-gel, chemical deposition, electrochemical, hydrothermal and in particular microwave-intensified approaches to prepare biomaterials with controlled pore size and morphology, as well as grow films on different substrates for use in drug delivery and tissue engineering.
  • Microwave Catalysis: The research work is coupling microwave irradiation with heterogeneous catalysis by using special reactors and a novel microwave-absorbing (MW) catalysts in a home-built system. This enables both microwave heating and microwave discharge assisted heterogeneous catalysis and the typical project in the group is microwave catalytic recycling of plastic.
