In the future, renewables will gain importance. Combining the use of CO2 as a feedstock along with the supply of renewable energy can compensate for fluctuations in energy production, while at the same time reducing CO2 emissions.
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.
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.
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.
The goal of this project is to perform an in-situ structural, morphological and compositional characterization of bimetallic electrocatalytic nanoparticles (NPs) both at the nanometer and the atomic scale. We will synthesize bimetallic NPs electrochemically and/or through colloidal chemistry, by tuning the ratio of different elements including Pt, Ni, Ag, Cu and Sn. The coexistence of
In the first phase, the activity, selectivity, and stability of the catalyst will be screened. Both commercially available and newly (self)-synthesized catalysts will be used for this purpose (Noblyst, Evonik; IrOx, Sigma Aldrich; Elyst Ir75 0480, Umicore). The most active, selective, and stable materials (Pt and IrOx) will then serve as a basis to synthesize

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.
