Carbon dioxide (CO2) photoreduction is attracting growing attention because of its potential to mitigate CO2 emissions and convert the captured CO2 to chemical commodities. The project also plans to identify the photocatalytic mechanisms of the catalysts by investigating the reaction systems, such as the interface morphology, structure coherence and energy alignment of the component phases and reactant. Innovative technologies in the field of sunlight-driven photocatalysis have the potential to significantly reduce greenhouse gas emissions.

A new strategy to enhance the performance of metal catalysts with sunlight

Project leader
Professor Huai Yong Zhu
Dates
2015-2019
Project summary

This project aims to develop photocatalysis of supported metal nanoparticles to drive various chemical synthesis reactions at moderate temperatures using sunlight. The nanostructures of plasmonic metals (gold, silver and copper) are used as light absorbers to concentrate the energy of incident light and generate intense electromagnetic field, which are utilised to promote the catalytic reactions on transition metals in the photocatalysts. The mechanisms of these new photocatalytic processes will be defined.

Successful completion of this project will result in new strategies for catalytic chemical synthesis and valuable knowledge within the areas of catalysis, conversion of solar energy to chemical energy, and nanomaterials.

Vertically aligned titanium oxide (TiO2) nanotube arrays have demonstrated remarkable properties for application in dyesensitised solar cell, photocatalysis, self-cleaning coating, purification of pollutants and orthopaedic implants. More excitingly, their architecture and dimensions can be precisely controlled using anodisation of titanium (Ti), creating considerable scientific interest and practical importance.

This project aims to develop novel techniques for determining the mechanical behaviour of TiO2 nanotube arrays and its dependence on crystal structure and geometrical parameters. The outcomes are expected to provide solutions to development of robust TiO2 and other nanotube arrays for broad applications in sustainable energy and tissue engineering.

Great Barrier Reef as a significant source of climatically relevant aerosol particles

Project leader
Professor Zoran Ristovski
Dates
2015-2017
Project summary

Every cloud drop is formed from a microscopic aerosol particle, known as a cloud condensation nuclei (CCN). In unpolluted environments the CCN particles originate from biogenic sources. Determining the magnitude and driving factors of biogenic aerosol production in different ecosystems is crucial to the development and improvement of climate models.

This project aims to determine the mechanisms of new particle production from one of the biggest ecosystems in Australia, the Great Barrier Reef. It is expected that the project will establish whether marine aerosol along the Queensland coast is coral-derived and show that this aerosol can affect the CCN concentration and therefore cloud formation and the hydrological cycle.

Revolutionising protection against air pollution

Project leader
Professor Lidia Morawska
Dates
2015-2017
Project summary

This interdisciplinary project aims to develop a personalised air pollution exposure monitoring system, leveraging the ubiquitousness and advancements in mobile phone technology and state of the art miniaturisation of monitoring sensors, data transmission and analysis. Airborne pollution is one of the top contemporary risks faced by humans; however, at present individuals have no way to recognise that they are at risk or need to protect themselves.

It is expected that the outcome will empower individuals to control and minimise their own exposures. This is expected to lead to significant national socioeconomic benefits and bring global advancement in acquiring and utilising environmental information.

These coatings represent a breakthrough in the field and will have a profound impact in many areas, including reducing infections related to medical implants and improving the efficiency of marine engineering systems.

Permanent concentration gradients captured in molecular and framework co-crystals

Project leader
Associate Professor John McMurtrie
Dates
2014-2018
Project summary

This project aims to design, synthesise and characterise molecular and framework co-crystals in which the molecular components are arranged in permanent concentration gradients. Synthetic crystals of this type are unprecedented. The concentration gradient has significant implications for the physical properties of the crystals (for example, optical, magnetic and electronic) as these must also vary in concert with the changing local molecular composition.

These co- crystals promise unique magnetic and optical properties that will influence design of new smart solid-state materials with potential for use in future high-technology applications.
