Nanoporous Iron-Based Oxygen Evolution Electrocatalysts for Water Splitting. This project aims to develop high-performance water splitting devices based on nanoporous iron-based oxygen evolution electrocatalysts.

This project aims to develop high-performance water splitting devices based on nanoporous iron-based oxygen evolution electrocatalysts. The devices, which will produce hydrogen to relieve the energy shortage in Australia, can be powered by photovoltaic and wind-generated electricity or directly use solar energy. The development of new energy materials that can be used to make renewable and clean fuels from abundant and easily accessible resources is among the most challenging and demanding tasks today. The combination of iron doping and nanoporous structure are intended to improve both the intrinsic and extrinsic catalytic activities of the electrocatalysts to be developed in the project.Read moreRead less
The development of resin and polymer based technologies for the recovery of copper and cyanide from gold processing tailings streams. This is a fundamental study on the use of resin and polymer-based ligands to recover copper and cyanide from gold cyanidation tailings. This process is environmentally more acceptable than other recovery methods, as it does not involve the use or generation of harmful species, such as HCN. It also has the advantage that copper metal and cyanide are recovered as pr ....The development of resin and polymer based technologies for the recovery of copper and cyanide from gold processing tailings streams. This is a fundamental study on the use of resin and polymer-based ligands to recover copper and cyanide from gold cyanidation tailings. This process is environmentally more acceptable than other recovery methods, as it does not involve the use or generation of harmful species, such as HCN. It also has the advantage that copper metal and cyanide are recovered as products from the copper cyanide containing streams. Thus the proposed project has the potential to substantially alter the gold recovery process, particularly in an era where environmental and public concerns exist over the discharge of cyanide species into tailings dams.Read moreRead less

Tuning the electrolytes for high efficiency solar splitting of water. This project will develop a new technology that uses ionic liquids and sunlight to split water into hydrogen and oxygen to be used as a clean fuel. Australia has abundant sunlight, is very close to the growing energy markets of the Asia-Pacific region, and is ideally placed to benefit from this new technology.

We have proposed an innovative method for treating copper containing ores which eliminates discharge of copper and cyanide to the tailings dam. The copper is recovered, and the cyanide is either recycled or destroyed within the plant. Another advantage of the process is a reduction in the cyanide requirement, hence reducing the risk associated with cyanide transport and storage. Thus the proposed project has the potential to substantially improve the gold recovery process, particularly in an era where environmental and public concerns exist over the use of cyanide.Read moreRead less
