Professor Tsang obtained his PhD from
University of Reading (1988-1991) and undertook post-doctoral research at
University of Oxford (1991-1993) and later becoming a departmental fellow at
Oxford (1993-1995). He obtained a Royal Society University Research Fellowship
Award (1995-2000). In 1996, he returned to Reading as a Lecturer (1996-2000)
at the School of Chemistry and then promoted as a Reader In Materials and
Catalysis (2000-2004). Recently, he has been appointed as Professor in
Nanomaterials and Catalysis (Aug 2004- present) heading the Surface and
Catalysis Research Centre and is Director of Research at the same school.
Novel Nano-Materials for Catalysis, Sensor and
Nanoscience is the study of phenomena at
the dimension of 1-100 nm but little has been achieved to tailor such small
nanomaterials for catalytic applications. By making use of unique combination
of expertise in both material chemistry and catalysis, Prof. Tsang and his
team are developing a leading expertise at Reading in nano-arechitecture of
catalyst particles. Their recent research has identified new directions
leading to rational designs of fundamentally more active and cost effective
In particular, the new concept has been on the appliance of novel
chemically-functionalised coatings onto nano-catalysts, rendering the nano-composite
catalysts highly active but separable from product. The precise manipulation
of individual catalyst particles at molecular level may lead to a new design
of modern catalysts (reviewed by iAc Newletter 2003 and The Chemical Engineer,
As a result, a new class of carbon coated magnetic separable nano-sized
catalysts has been developed at Reading (Angew Chem. in press). In a related
subject, an account of new silica coated nano-magnet of controlled dimensions
to host biocatalysts with many unique advantages is disclosed (Chem Comm,
2003). His team has also developed new encapsulated nano-catalysts that
control the composition/size of the core (J Phys Chem, Chem Comm 2003). This
time, the core contains catalytically active sites, which are protected by a
porous oxide coating of tailored size. It offers an exciting possibility of
independently optimising the important local metal to oxide (coating)
interactions that has never been achieved, for catalytic reactions.
His team also work on development of micro-emulsion nano-catalysts in
supercritical carbon dioxide (scCO2) as a new environmental friendly process
that represents a new but greener approach for the production of chemicals
(Chem. Comm 2002, Langmuir 2004).
In nano-sensor and biomedical areas, their interests include using hollow
carbon nanotube as nano-scale test tube (two articles in Nature, 1994) for
catalysis, separation, storage, magnetic, electronic applications. Research on
attachment, testing and characterizations of enzymes and DNA in opened carbon
nanotubes at Reading are underway (Angrew. Chem; Chem Comm, 1997-1998). These
studies open up promising lines allowing developments of biosensors or drug or
gene-delivery/ storage methods (patents & ongoing projects with Astrazeneca
2002-2004) as well as nano-surgerical devices. Also, very recently, Prof.
Tsang is working on new synthesis of materials (magnetic, radionuclides)
encapsulated in nano-carbon onions. By teaming up with Manchester hospital
important applications of these encapsulated radioisotopes in onions for
medical diagnosis are being developed (Advanced Materials 2004).

A number of international patents have been filed in
collaborations with companies, which will enable Reading to commercially
exploit their patents on nanomaterials.
