The main objective of the project is the development of technologies for the conversion of CO2 to value-added chemicals using catalysis and renewable energy. To benchmark, compare and develop the various technologies, the formation of formic acid is selected as the initial target.
Climate change and global warming has become a growing threat to our world, where the carbon dioxide emisisons are believed to be a major contributor. In order to serve the society and environment, the Sustainable Chemistry department of VITO has been focusing since recent years on CO2 valorization, mainly on the development of conversion technologies.
Processes in energy applications and catalysis as well as biological processes become increasingly important as society’s focus shifts to sustainable resources and technology. A thorough understanding of these processes needs their detailed observation at a nano or atomic scale.
The overall objective of the project is to stimulate investment in and implementation of Power-to-X technologies by developing innovative direct and indirect conversion processes for the chemical industry towards higher TRL’s, while making use of renewable electricity and lowering the carbon footprint.
Recent advances in extending the light absorption range of titania (TiO2) into the visible region has resulted in a new material, i.e. black TiO2 with a bandgap around 1.5 eV. Black TiO2 is a promising candidate for photo-(electro)catalysis under near infrared light owing to its narrow band gap and its improved electronic conductivity which only limited attention has been paid to it to use as a photoelectrochemical sensor.
Functionalization of inert carbon-hydrogen (C-H) bonds is an important reaction in the chemical industry. The introduction of functional groups (e.g. oxygen, nitrogen, sulfur, … atom) in otherwise inert molecules is necessary to construct more complex molecules for the bulk and fine chemicals industry.
Renewable energy sources can offer a solution for excessive emissions of greenhouse gases and to the expected decrease in availability of fossil fuels in the near future. Both problems would find a common solution if we were able to develop energy-efficient processes to convert (low concentrated) CO2 streams into fuels and useful chemical products, ensuring a positive economic
and environmental balance.
Previously an active passive sampler for accumulation of pollutants from water was developed into a laboratory prototype. Its n°1 feature is controlled flow through the device, such that sampling is independent of hydrodynamic flow in the water body. This project will establish a field-deployable prototype. Its valorization value lies in standardization and the replacement of biota sampling.
Catalysis is a key technology to achieve more efficient and greener organic synthesis. Complementary expertise on the development of new (homogenous and heterogeneous) catalysts (redox, photo and electrocatalysis) will be brought together with organic synthesis know-how in one center.
Over the last decade, the use of nanotechnology in electrochemical catalysis has become extreme important. Sole nanoparticles, however, do not yet constitute an electrode. Hence, deposition on a conducting support structure is indispensable

In the last decades, the amount of CO2 in the earth’s atmosphere has increased enormously. Due to the goals set by Europe, CO2 mitigation is of major importance for industry as well as society.
The project aims to develop an active passive water sampler for inorganic and organic pollutants. The apparatus allows the time integrated monitoring of surface waters and waste streams.
The goal of this project is the development of a generic platform for electron paramagnetic resonance spectroscopy (EPR) to unravel the electrocatalytic reaction mechanism.
In recent years there has been a growing interest in clean and environmentally friendly methodologies in organic synthesis. To tackle these issues, an electrosynthetic methodology can be applied.
The goal of this project is the integration of plasma and electrochemical applications into a generic microreactor setup.
The production of organic chemicals by means of electrosynthesis can dramatically increase reaction efficiency. The approach of this project is to construct a prototype reactor setup to facilitate the transition from classical chemical towards electrochemical pathways.
Corrosion is a common phenomenon that causes detrimental economic and social consequences. An obvious way of corrosion protection is to prevent the metal surface from being exposed to a corrosive environment by application of one or several coatings, usually conversion coatings.
Impedimetric aptasensors consist out of two key elements: an aptamer as biologic recognition element and electrochemical impedance spectroscopy (EIS) as detection method.
