Description

Project summary

Heterogeneous photocatalysis has become a subject of great interest with important potential applications in environment (water and air depollution), solar energy conversion and solar fuel production (mainly H2). Titanium dioxide (TiO2) is the most investigated and used semiconductor because of its high photocatalytic activity, stability, low cost, and nontoxicity. Solar light is a green and renewable source of energy that can be used for either water depollution or hydrogen production.

The main challenge of the PhD project will be the design of bioinspired Z-scheme photocatalyst with a Yolk-Schell structure that exhibit high photocatalytic activity for water treatment and hydrogen generation under visible light. The Z-scheme photocatalyst design appears as a promising strategy to mimic Nature (leafs-bioinspired) for hydrogen production and depollution applications.

 

The scalable Z-scheme photocatalyst with an heteronanostructure based on coupling TiO2 with semiconductors having variable band gap and non-noble nanoparticles will be carried out using soft-chemistry (sol-gel process) and radiolysis. A strict control of the synthesis conditions will be performed to adjust the heterojunction connection and nanoparticles to achieve an efficient charge carriers transfer between materials. The Z-scheme photocatalyst will be finally self-assembled as a photonic crystal and the slow photon effect will be also studied.

The charge carriers’ mobility, texture, structure, photocatalytic efficiency as well as the optical properties of the obtained materials will be characterized using Time Resolved Microwave Conductivity (TRMC), UV-visible spectroscopy, TEM, FTIR spectroscopy, X-ray diffraction and scanning electron microscopy.

The expected synergistic effect between the heterojunction and the non-metallic nanoparticles will be assessed for hydrogen production and depollution process.

Description

The titanium dioxide TiO2 exhibits photocatalytic activity that was first considered harmful, because it leads to the degradation of organic matrices in which the white pigment is incorporated. The ability to use these properties in applications related to the environment and energy, such as the elimination of organic pollutants in water and air or hydrogen production, has generated renewed interest in the scientific community for TiO2.

 

The objective of this work is the development of a mesoporous TiO2-based photonic crystal (Bragg stacks) showing a high photocatalytic activity, photon tenability and activity in the visible range. The development of a material with specific properties requires an understanding of the relationship between the elaboration, structure (crystalline structure and microstructure), the dynamics of charge carriers (electronic properties) and the photocatalytic activity of the material. This requires two steps coupled between them: Elaboration versus Characterization (structural, electronic and photocatalytic).

 

In this work, the mesoporous photonic crystal will be obtained by alternating thin mesoporous films of TiO2 and other semi-conductors using soft-chemistry (sol-gel process). The mesoporous TiO2 films will also be coupled by plasmonic nanoparticles (localized into the pore) by gamma radiolysis of metal complexes. The synthetic procedure will be tuned to insure an optimal film’s interconnection, thickness, crystallinity, optical properties, electron transfer, light harvesting etc.

 

The electronic properties will be studied by Time Resolved Microwave Conductivity (TRMC) to measure the lifetime of charge carriers created by illumination of the photocatalyst. The structure, texture and optical properties of the mesoporous photonic structure will be assed will be characterized using Time Resolved Microwave Conductivity (TRMC), UV-visible spectroscopy, FTIR spectroscopy, X-ray diffraction and scanning electron microscopy.

 

The photocatalytic properties of the samples will be determined by photodegradation of phenol in water and hydrogen production from methanol.

Immediately available is a PhD scholarship in the research and development of intrinsic ferromagnetic semiconductor materials for spintronic device applications. Analogous to electronics, spintronics uses the magnetic moment of the electron, rather than the charge, to process and store information. Intrinsically ferromagnetic semiconductors are expected to form the core of true spintronic systems, but very few examples are known. This research project will investigate one such material using synchrotron and neutron scattering techniques, culminating in its characterisation in an integrated spintronic device.

The scholarships cover the national/international fees (International: 32,000AUD/yr), and provides an annual stipend of ~25,000AUD. The PhD provides approx 15,000AUD for travel and research costs.  AU/NZ candidates will also be eligible to apply for AINSE top-up scholarships of 7,500AUD.

We are seeking PhD candidates in the development of algorithms for quantum computing and quantum measurement. Quantum computing involves manipulating quantum systems, such as individual atoms or photons, to process information in a fundamentally different way than regular computers, and achieve much higher speed.  Similarly, quantum measurement involves using quantum systems for high precision measurement, for example of distance, or nanoscale magnetic fields. PhD projects will involve developing the new techniques needed for this highly advanced technology of the future.

PhD scholarships that can support potential candidates cover the national/international fees (International: 32,000AUD/yr), and provides an annual stipend of ~25,000AUD. The PhD provides approx 15,000AUD for travel and research costs.
