With the exponentially growing portion of electricity generated from renewable resources (solar, wind, and tidal power) in total electricity production throughout the globe, the mission of implementing environment-friendly energy storage technology is even more important to the future sustainable economy.
Supercapacitors are expected to overcome the storage and the charging speed of the traditional batteries in the near future, opening new avenues for renewable energy resources. Graphene and its compounds, graphene oxide, nanotubes, are targeted as materials to increase the charge accumulation in thin film supercapacitors.
Graphene is a 2D material, which is expected to hold a large amount of charge, as required by supercapacitors. Amongst the possible routes of preparation, the reduction of graphene oxide is one of the cheapest. Defects and pores in the graphene oxide 2D lattice may lead to a further increase of the capacitance.
The project involves:
- Film preparation by filtration methods,
- Microscopic studies by Scanning Electron Microscopy, Transmission Electron Microscopy, Atomic Force Microscopy,
- Chemical characterization by X-ray Photoelectron Spectroscopy, Raman, UV-Vis
- Capacitor preparation on glass or polymers
- Capacitance characterization by I-V and C-V measurements
- Data analysis and interpretation
The specific activities will be tailored to the level of the student (V-RES, Honours, Master, PhD) and to the available time. The student will work in an exciting, well-established, highly collaborative research group environment, using the most advanced instrumentation available at CARF, providing the opportunity for an effective and rich learning experience.
The team includes Professor Nunzio Motta, expert in 2D materials for energy storage and in surface science, Dr Jennifer MacLeod, expert in surface science, molecular self assembly of 2D materials and graphene and an excellent group of PhD students and Post docs. The student will also benefit of an outstanding collaboration network including QUT researchers and international scientists.
