Dr Dmitry Bavykin is Associate Professor Energy Technology within Engineering and Physical Sciences at the University of Southampton.

Dr. Dmitry Bavykin is a specialist in the area of nanomaterials and photocatalysis with more than 20 years experience of research and problem solving using a variety of scientific techniques. He was awarded a one year Royal Society/NATO Fellowship for posdoctoral studies in 2002 for undertaking research in Bath University. These studies, which were supervised by Professor Frank C. Walsh and Dr Alexei Lapkin, explored the synthesis, characterization and application of nanotubular titanates and TiO2, which have applications in electrochemistry and catalysis. During this time he started to work on the compact reactor systems under supervision of Dr. Pawel Plucinski and Dr Alexei Lapkin.

His ambition is to use his background in material chemistry and physical chemistry to develop TiO2 (or other) nanotubular based self-assembled systems (thin film electrodes, catalyst coatings) having desired location of different functionalities and use of such system for different energy related modern challenges (hydrogen storage, lithium batteries, solar and fuel cells).

Research interests

Technological methods for synthesis of nanotubular materials.

The studies of preparation, characterization and application of multiwall inorganic nanotubes have been a subject of many investigations in recent years. My primary research interests are focused on the mechanisms of spontaneous (templateless) formation of multilayered inorganic nanostructures (nanotubes, nanowires), an understanding of which would potentially allow significant control over the morphology of known and novel nanostructured materials.

This research is also accompanied by the development of technological methods of targeted fictionalization and manipulations of nanostructures, adapting them to various applications. The list of nanostructures includes

  • Titanate and titania nanotubes, nanofibres, nanorods
  • VOx nanotubes
  • Complex silicate such as halloysite (Al2Si2O5(OH)4), nickel silicate (Ni3Si2O5(OH)4) nanotubes
  • Multiscale hierarchical structures.

 Energy application of nanostructured materials.

Due to the increased specific surface area and open pores network, elongated nanostructures of metal oxide can potentially be used in various applications. Our current research considers application of inorganic metal oxide nanotubes in

  • Solar cells (dye sensitized or exitonic) with improved current collection efficiency.
  • Lithium batteries (3D electrodes with improved power and capacity)
  • Hydrogen storage at ambient conditions
  • Systems for photocatalytic generation of hydrogen.

 Other applications of inorganic nanotubes and composites

The elongated shape and long length of ceramic nanotubes and nanofibres allows an improvement of mechanical and triboligical properties of their composites with polymers and metals.

The interior of nanotubes (inner pores) can be also exploited as a capsule for drug delivery with controlled release of the drug.

Good adhesion of titanate nanotubes with upconverting (NaYF4)nanoparticles can be used in photodynamic therapy.
