To use exhaust gas and waste for the production of new products is a vision that persists since the beginning of human production.
Nowadays, it became an imminent necessity to deal with the ever increasing production of “useless” CO2 as the result of employing fossil resources.
So far, there is no viable technology to deal with this. It would therefore be a major breakthrough to enable the efficient conversion of CO2 into “useful” compounds using renewable energy and resources, the main goal of DIACAT.
The project became possible only by technologies recently developed by the DIACAT consortium, such as controlled growth of (nano)structured diamond materials by chemical vapour deposition (CVD), production of diamond nanoparticles by mechano-chemical means, diamond surface chemistry etc.
Some fundamental knowledge on the formation of high energy solvated electrons at diamond surfaces has been reported. But the photocatalytic reduction of carbon dioxide using diamond materials is still a very new field; with only preliminary experiments already performed.
The basic principles of the photocatalytic reduction using other materials than diamond have been investigated; however, until now no commercial device has been presented to the best of our knowledge.
This is where this project starts by providing the European Research Area with an innovative concept and a new technology for the efficient generation of high energy electrons for chemical reactions using energy from renewable sources such as visible light and thus enabling the development of a new, sustainable technology for the revalorization of carbon dioxide.
