Process studies for photocatalytic rejuvenation of spent industrial Bayer liquor. A new low-energy photocatalytic process for the continuous treatment of spent liquor from the Bayer process for alumina production has been demonstrated. This new technology can process up to 1500 litres of industrial caustic effluent per day with a reduction in carbon dioxide release. The photo-treated refinery wastewater also provides water savings of 30 per cent.

This project aims to develop multifunctional single site catalysts and collaborative surface sites to complete multi-step reactions using carbon dioxide (CO2) hydrogenation to higher alcohols with enhanced selectivity for large-chain alcohols. CO2 is an abundant and renewable carbon source for use as a feedstock, and closing the carbon cycle in an energy efficient manner has the potential for significant environmental benefits. The project is expected to advance the knowledge in rational design of new catalysts for CO2 conversion and understanding the catalyst structure-property induced reaction mechanism. This will result in an improved understanding of the reaction kinetics of utilising CO2 as a feedstock.Read moreRead less

A novel route to produce olefin feedstock for Australia. This project aims to develop a new process to produce longer chain hydrocarbons usable in Australia's olefin and polymer industries. Besides their use as a fuel, hydrocarbons are major industrial chemicals used for the production of polymeric materials and as refrigerants. Olefins are precursors to polymers and conventionally are produced from saturated hydrocarbons through the process of steam cracking.

This project aims to develop a new process to produce longer chain hydrocarbons usable in Australia's olefin and polymer industries. Besides their use as a fuel, hydrocarbons are major industrial chemicals used for the production of polymeric materials and as refrigerants. Olefins are precursors to polymers and conventionally are produced from saturated hydrocarbons through the process of steam cracking. The major precursors for monomers are present in significant quantities in only a few natural gas sources and these sources also undergo significant seasonal variation and are costly. The project aims to develop new catalysts and process conditions to convert low-value feedstock hydrocarbons into feedstock for conventional steam crackers.Read moreRead less

This project aims to understand the interaction of light responsive nano-metals and metal oxide supports in photo-thermal catalysis, and channel light and heat to efficiently drive catalytic reactions. From this understanding, it will develop principles to activate the active site of metal oxides and control catalytic activity with high selectivity and stability. It will use this knowledge to selectively oxidate methane and oxidative coupling of methane reactions. The expected outcome is an inexpensive green catalysis method for chemical manufacture. This should lower the amount of waste, decrease energy consumption and improve human health, finite global resources and quality of life.Read moreRead less

The overall aim of this project is to assemble multi-functional nanocomposites for carbon dioxide reduction by an integrated catalytic and photocatalytic approach. The issues of impending depletion of fossil fuel resources and irreversible climate change due to carbon dioxide emissions have stimulated research for the sustainable utilisation of carbon dioxide. In situ spectroscopic studies combined with theoretical calculations will be used to elucidate the underlying reaction mechanisms of the synergistic effects of photon and thermal reduction of carbon dioxide . The success of the proposed project will allow the reduction of carbon dioxide, generate a cheap energy source in the form of environmentally benign hydrocarbons and close the carbon loop.

Highly-efficient, reversible fuel cell. This project aims to develop a reversible fuel cell - electrolyser capable of storing electricity (in the form of hydrogen gas) with the same overall energy efficiency as the best present storage system, pumped hydro. Whereas pumped hydro requires large infrastructure like dams, the proposed cell will be extremely inexpensive and easily scalable.
