The proposed project aims to develop a novel photocatalyst, prepared by doping nanocrystalline TiO2 with noble metals, for use in photoreduction reactions. The ability of this photocatalyst to reduce heavy metals and its potential to generate H2 in an inert environment will be explored. The project will benefit the environment by removing toxic compounds from polluted wastewaters as well as potentially generating substantial levels of H2 (an attractive energy source). Project outcomes include the development of an economical and cleaner process for treating waters contaminated with heavy metals and providing a valuable knowledge base from which photoreductive efficiencies can be drawn.Read moreRead less

Summary
Nanostructure Tailoring of Inorganic Membranes by Rapid Thermal Processing. This project aims to produce inorganic membranes with desired nanostructures using a Rapid Thermal Processing (RTP) technique for gas separation applications. The key concept of the research is that the RTP will be able to achieve thin-film membrane layer with a finer microstructure and pore size control without heat stress-induced cracking. RTP aims to deliver superior membrane performance with less than 10 per cent of ....Nanostructure Tailoring of Inorganic Membranes by Rapid Thermal Processing. This project aims to produce inorganic membranes with desired nanostructures using a Rapid Thermal Processing (RTP) technique for gas separation applications. The key concept of the research is that the RTP will be able to achieve thin-film membrane layer with a finer microstructure and pore size control without heat stress-induced cracking. RTP aims to deliver superior membrane performance with less than 10 per cent of the fabrication time compared to normal slow calcination. The outcomes of this new technology aims to make inorganic membranes a commercial reality and maximize the membrane manufacturing capability and productivity of petrochemcial, chemical and clean coal/energy industries.Read moreRead less
Application of Water Based Fractionation in the Assessment of Metallurgical Coal. The metallurgical coal market (13% of coal market) is highly specialized, and competitive. The coal, which is utilized as a reducing agent in iron making, represents more than 52% of Australian coal exports. This study addresses growing evidence that organic liquids used to fractionate and in turn assess metallurgical coals lead to negative assessments, hence loss of markets, and lost opportunities.

The coal, which is utilized as a reducing agent in iron making, represents more than 52% of Australian coal exports. This study addresses growing evidence that organic liquids used to fractionate and in turn assess metallurgical coals lead to negative assessments, hence loss of markets, and lost opportunities. A new water based fractionation method will be established, and a systematic investigation into the effects of the organic liquids will be undertaken. These results will be used to build a case for replacing the organic liquids used in the industry, which are known to have negative health and environmental impacts. Read moreRead less
