Metal-organic frameworks (MOFs) are an emerging class of crystalline materials that hold huge promise for significant applications such as adsorption, separation, catalysis and drug delivery. Attributed to their exceptional porosity and surface area, the adsorptive performance of MOF materials has high potential for solving challenging issues such as hydrogen storage, greenhouse gas capture and water vapour harvest in arid regions.
However, the practical application of many MOF materials encounters challenges from poor chemical stabilities, low yields and expensive manufacturing costs. With this in mind, we've developed a method to load MOF crystals onto natural minerals to address thermal and chemical stability while retaining high porosity that enables the highest hydrogen storage capacity reported to date.
Based on this preliminary success, this project aims to further explore nano/micro-scale, locally-sourced minerals as supporting materials for MOFs in order to provide improved properties and capacities for hydrogen storage. Being the 'university for the real world', this project will not only concentrate on academic innovations but also solutions to practical problems.
In this project, existing and undeveloped sources of industrial minerals abundant in Australia will be evaluated for the fabrication of different MOF-composite materials. These minerals may include:
A combination of the two products/techniques via laboratory synthesis will further lead to high value-added gas storage products with high performance and improved cost efficiency for clean energy development.
You'll gain valuable and practical experience in the development and characterisation of these novel materials under the supervision of experienced scientists in this research field, including:
- Associate Professor Xi, a program leader
- Professor Mackinnon, the founder of the newly established Centre for Clean Energy Technologies and Practices at QUT.
Depending on the level of study the objectives are to research and develop:
- innovative materials that have high hydrogen storage capacities (Masters, PhD)
- a fundamental understanding, at a microstructural level, of advanced energy storage materials (Masters, PhD)
- theoretical construction of the relevant reactions and mechanisms under the framework of mineralogy, crystallography and materials science. (PhD).
