This project aims to address the fundamentals and applications of regulating micropore accessibility. It has long been known that some highly adsorbing molecular sieves suddenly become inaccessible to gases below certain temperatures. Following a recent breakthrough in elucidating the mechanism of such temperature-regulated guest admission, this project will explore electrical regulation of micropore accessibility in conjunction with developing new mechanisms, materials, and control tools for applications, including tunable molecular sieves, valves and gas encapsulation devices. The outcomes of this project will generate new knowledge in the active manipulation of the admission and release of guest molecules in/out of microporous materials, and establish new expertise and capabilities that can advance gas separation, storage and sensing technologies. It is expected that this project will contribute to the long term benefit in low emission energy supplies and Australia's natural gas industry, improve the separation efficiency of our chemical industry, and boost the development of the hydrogen economy.Read moreRead less
Novel conversion process for carbon dioxide to chemicals. This project aims to develop a novel sorption enhanced material and system to convert atmospheric carbon dioxide (CO2) to methanol. Climate change is one of the primary long-term problems confronting humankind today. Since the production of CO2 through burning fossil fuel is far greater than the current usage of CO2, there is currently little alternative to storage. As a result, there is concerted effort globally to develop alternate use ....Novel conversion process for carbon dioxide to chemicals.
