Electrocatalytic Generation of Ammonia from Air and Water. The aim is to directly convert nitrogen under mild conditions, using renewable power, to form ammonia for fertilisers and fuels, enabled by new, nanostructured, electrocatalysts based on single-sheet and composite materials. Unlike nitrogen fixation using a three-electrode system, the project will use a novel mixed gas- and liquid-phase electrocatalytic nitrogen reduction two-electrode reactor. Based on fuel cells, it is designed to acce ....Electrocatalytic Generation of Ammonia from Air and Water. The aim is to directly convert nitrogen under mild conditions, using renewable power, to form ammonia for fertilisers and fuels, enabled by new, nanostructured, electrocatalysts based on single-sheet and composite materials. Unlike nitrogen fixation using a three-electrode system, the project will use a novel mixed gas- and liquid-phase electrocatalytic nitrogen reduction two-electrode reactor. Based on fuel cells, it is designed to accelerate the naturally sluggish nitrogen reduction reaction, NRR, significantly improving the reaction rate and selectivity. The project will also gain atomic-level understanding of the mechanism of NRR, based on in-situ spectroscopies used under operando conditions, e.g., Raman or X-ray absorption.Read moreRead less
Catalytic conversion of Australia's natural gas to value added products. While natural gas (of which methane is the primary component) is an abundant source of energy, it is normally found in remote areas and for its successful exploitation it needs to be processed. The processing usually requires significant energy and resources input. In this project we will develop a fundamental understanding to a single step catalytic process that can utilise natural gas and nitrous oxide (both potent greenh ....Catalytic conversion of Australia's natural gas to value added products. While natural gas (of which methane is the primary component) is an abundant source of energy, it is normally found in remote areas and for its successful exploitation it needs to be processed. The processing usually requires significant energy and resources input. In this project we will develop a fundamental understanding to a single step catalytic process that can utilise natural gas and nitrous oxide (both potent greenhouse gases) and oxygen to produce selectively methanol and hydrocarbons from a natural gas feedstream in a controlled manner. A single step process for natural gas conversion utilising waste green-house gases is expected to be of great benefit to the Australian economy, environment and energy securityRead moreRead less
Advanced chemical recycling of mixed plastics for monomer recovery. This project aims to develop innovative catalytic routes to the chemical recycling of mixed plastics for recovery of their molecular building blocks. Plastic pollution poses a significant threat to the Australian ecosystem. Efficient recycling technologies are urgently needed as Australia only recycles ~4% of its 3.4 million tons of mixed waste plastics. This project expects to design highly efficient catalysts for the stepwise ....Advanced chemical recycling of mixed plastics for monomer recovery. This project aims to develop innovative catalytic routes to the chemical recycling of mixed plastics for recovery of their molecular building blocks. Plastic pollution poses a significant threat to the Australian ecosystem. Efficient recycling technologies are urgently needed as Australia only recycles ~4% of its 3.4 million tons of mixed waste plastics. This project expects to design highly efficient catalysts for the stepwise breakdown of mixed polyolefin plastics into monomers for the subsequent manufacturing of virgin plastics in a circular economy, and to elucidate fundamental underpinning reaction mechanisms. Outcomes will stimulate the Australian waste plastic recycling industry, and minimise plastic accumulation in the environment.Read moreRead less
Scale-up of catalytic furandicarboxylic acid production at room temperature. This project will use new knowledge acquired from our laboratory-scale discoveries to develop a new process feasible for industrial-scale production of 2,5-furandicarboxylic acid (FDCA). The method makes FDCA, a platform chemical for future chemical industry, from a completely renewable source derived from plant sugars, 5-hydroxymethyl-furfural.

This project will use new knowledge acquired from our laboratory-scale discoveries to develop a new process feasible for industrial-scale production of 2,5-furandicarboxylic acid (FDCA). The method makes FDCA, a platform chemical for future chemical industry, from a completely renewable source derived from plant sugars, 5-hydroxymethyl-furfural. This is an essential process for production of biodegradable plastic from sugar that has not been commercialised. This technology will realise sizeable industrial-scale production of FDCA at low costs and without heating. The production development of this valuable commodity from renewable plant sugars will provide high-quality postgraduate training in future green chemical production methods.Read moreRead less
Mechanisms of Ammonia (NH3) Combustion and Nitrogen Oxides (NOx) Formation. A mature commodity that can be readily made from renewable resources, ammonia (NH3) offers an environmentally sustainable and low-cost means of transition from fossil fuels to a clean, low-carbon and renewable energy future.

A mature commodity that can be readily made from renewable resources, ammonia (NH3) offers an environmentally sustainable and low-cost means of transition from fossil fuels to a clean, low-carbon and renewable energy future. The technical challenge is to combust NH3 efficiently with low nitrogen oxides (NOx) emissions. This project will advance the science of NH3 combustion and NOx formation. By applying innovative fixed-bed and fluidised-bed reactor techniques and kinetic modelling, the research will unravel fundamental characteristics and mechanisms of NH3 combustion, NOx formation and in-situ destruction that underpin the development and deployment of practical combustion systems for power generation using NH3 as a carbon-free fuel.Read moreRead less
