Research focus: Artificial Photosynthesis, solar fuels, the conversion of CO2 to hydrocarbon chains and photocatalysis
Modifying Titanium Dioxide nanoparticles to make them a more efficient photocatalyst for the conversion of CO2 into fuel, PhD student Nikolaos Moustakas is contributing to an important area of energy research.
Nikolaos’ PhD research project aims to achieve the conversion of CO2 into hydrocarbon chains using modified Titanium Dioxide (TiO2) nanoparticles as a photocatalyst in a process called artificial photosynthesis. “In the same way that plants exploit solar energy, water and CO2 in order to cover their energy needs, or glucose”, says Nikolaos, “we are trying to use light irradiation and water to convert CO2 into long hydrocarbon chains that can be used as fuels”. So far the process of artificial photosynthesis to produce so-called solar fuels has been achieved under UV light, which covers only about 4% of the total solar spectrum. Nikolaos is attempting to modify the process so that it could be carried out under the visible part of the solar spectrum, which would be a huge step forward in the efficiency of the approach. As Nikolaos says, “if research manages to find a material and a device that can (in an inexpensive and environmentally safe way) efficiently convert CO2 into fuel – we could greatly contribute in solving the energy crisis and tackling the greenhouse effect”.
Describing the importance of artificial photosynthesis for sustainable development, Nikolaos highlights its potential as a two-tiered solution. “Artificial photosynthesis is a ‘green’ procedure, as it uses CO2 – a greenhouse gas – that would otherwise be released into the environment and transforms it into something useful that can be used as fuel. It is an ideal concept that simultaneously combats the greenhouse effect and the energy crisis”. He particularly enjoys working in such an interdisciplinary field, which connects physics, chemistry, material science and chemical engineering. Nikolaos is also conducting other photocatalytic experiments such as using micro-filtration to purify water.
The Jury lauded Nikolaos’ innovative approach to this important area of research. His experiment is making a real contribution to its progress and the impact of perfecting artificial photosynthesis could be enormous.
