Highly visible light responsive black titania for photo-electrochemical applications: the electrosensing of polyphenols in flow mode

past, Projects /

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.

Fundamental insight into the role of the support and electrocatalyst in CO2 electrolyzers: are carbon-based materials the solution or the problem?

past, Projects /

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.

Quantitative in-situ structural, morphological and compositional characterization of bimetallic nanoparticles as a route towards innovative electrocatalysts

past, Projects /

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

Electrosynthesis for the sustainable production of ethylene oxide

past /

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

New redox mediators and improved electrocatalytic materials for the functionalization of carbon-hydrogen bonds by electrosynthesis

past, Projects /

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.

Towards a targeted optimization of electrocatalysts by combining electrosynthesis with in-situ electron paramagnetic resonance

past /

In recent years, there has been a growing search for clean, environmental friendly methodologies for organic synthesis. Organic electrochemistry offers an interesting alternative to tackle the issues for organic transformations. Electrochemical synthesis mostly needs fewer steps and produces less waste with the electron as a cheap, clean and energetically efficient reagent. However, the applicability of

Innovative three-dimensional electron microscopy to boost the catalytic activity of core-shell nanostructures

past, Projects /

Electron tomography has evolved into a state-of-the-art technique to investigate the 3 dimensional structure of nanomaterials, also at the atomic scale. However, new developments in the field of nanotechnology drive the need for even more advanced quantitative characterization techniques in 3 dimensions that can be applied to complex (hetero-)nanostructures.
