Engineering defect-intensive ozonation catalysts to degrade micropollutants. This project aims to engineer unique particles containing defect-intensive surfaces which are designed to accelerate the catalytic ozonation of waters contaminated with pharmaceuticals and other recalcitrant pollutants. This will enable timely treatment of industrial waste water as well as sewerage treatment plant effluents using simple and cheap catalyst materials. Wet- and flame-based particle fabrication technologies ....Engineering defect-intensive ozonation catalysts to degrade micropollutants. This project aims to engineer unique particles containing defect-intensive surfaces which are designed to accelerate the catalytic ozonation of waters contaminated with pharmaceuticals and other recalcitrant pollutants. This will enable timely treatment of industrial waste water as well as sewerage treatment plant effluents using simple and cheap catalyst materials. Wet- and flame-based particle fabrication technologies paired with unique post-synthesis treatment strategies, including either a coupled hydrogenation-illumination approach or plasma exposure, will be implemented for defect manipulation so as to produce new cheaper, stable, and higher-performing catalysts for activating ozone to treat water containing pharmaceutical and endocrine disrupting micro-pollutants under different process conditions.Read moreRead less
Controlling arsenic to unlock value in gold and copper resources. This project aims to characterise the transformation of arsenic between oxidation states during mineral processing. Up to one third of the world’s gold reserves are locked up in arsenic rich minerals and 5000 tonnes of arsenic is released annually from mine waste. The project will enable the development of process technology that immobilises and removes arsenic at the earliest possible stage. The use of novel time-resolved in-situ ....Controlling arsenic to unlock value in gold and copper resources. This project aims to characterise the transformation of arsenic between oxidation states during mineral processing. Up to one third of the world’s gold reserves are locked up in arsenic rich minerals and 5000 tonnes of arsenic is released annually from mine waste. The project will enable the development of process technology that immobilises and removes arsenic at the earliest possible stage. The use of novel time-resolved in-situ techniques proposed in this research will give vital information of the complex chemical pathways involved during processing which current characterization methods on pre- and post-processed species do not achieve.Read moreRead less
