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

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

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 develop innovative catalytic systems on semiconductor surfaces, to use sunlight for conversion of carbon dioxide (CO2) into high energy-content products. Sustainable chemical transformation of CO2 into valuable products, especially fuels, is one of the most important chemical processing challenges. This project will use innovative molecular engineering to covalently fix light-harvester to semiconductors. The expected outcome will be an efficient system to enhance CO2 conversion, which will not only reduce the environmental impact but also generate a cheap source of energy by closing the carbon loop. Using this approach, existing high carbon-emitting processes will be able to be replaced by new carbon-neutral or even carbon-negative ones for much-reduced environmental impact on our society.Read moreRead less
