hotocatalystmaterialswhich are suitably stable often have
large band gaps and can only be activated by UV light. Our
recent researchhas involved the synthesis andmodificationof
novel inorganic nanostructured materials in order to exploit
their properties in visible light active photocatalytic systems.
We have shown that self-assembled surface modification
by organic molecules imparts trititanate nanotubes with
stable, recyclable photocatalytic activity under visible light
illumination. Using solid state NMR, XRD and Mass spec
we have recently been looking into the arrangement of the
organic molecules on the nanotube surface. We have also
prepared titanium dioxide nanotube arrays by anodization
for photoelectrochemical water splitting and modified them
with Au and MoS

for comparison.
Speaker Biography
Dr. Graham Dawson is currently a lecturer at Xi’an Jiaotong Liverpool University, Suzhou
China, joining in March 2013. Before taking this position he worked at the Suzhou
Institute of nanotechnology and Nanobionics (SINANO) as a postdoctoral research
assistant then as an associate professor. During this time, Dr. Dawson was principal
investigator of several provincial and national level projects. He completed his PhD
studies under ProfessorWuzong Zhou at the University of St. Andrews, Scotland and has
presented his research at several national and international conferences and published
papers in peer reviewed international journals. Dr. Dawson’s research interests are in
the area of nanomaterial synthesis towards applications in photocatalytic degradation
and water splitting.
