The demand for clean, secure and sustainable energy sources has stimulated great interest in electrochemical energy storage and conversion technologies such as water splitting and fuel cells. The efficiency of water splitting and fuel cells is however strongly dependent on the activity of the electrocatalysts. The objective of the project is to develop new electrocatalysts based on the recently discovered phenomena that carbon nanotubes with specific size and number of walls are very active and significantly promote the reaction of water splitting and fuel cells. The proposed project is expected to open a new research field in the development of new electrocatalysts and photoelectrocatalysts for advanced energy conversion and storage technologies.Read moreRead less
Corrosion of heat resisting alloys in steam/hydrogen-rich environment . Hydrogen is a clean fuel for energy future.

Hydrogen is a clean fuel for energy future. Its production and utilisation unavoidably involve water vapour and hydrogen at high temperature which is however corrosive to materials used in the system. This project aims to investigate corrosion behaviour of heat resistant alloys in the presence of both hydrogen and water vapour, mechanisms of water transport in oxide scale, and the effect of hydrogen on water vapour corrosion. Alloying effects on corrosion rates will be defined and methods of slowing or preventing water vapour corrosion in the presence of hydrogen will be devised. The results will provide a basis for improved design/selection of heat resisting alloys for hydrogen production and hydrogen utilisation industries.Read moreRead less
