Welcome to our new website
Welcome to the new website of the research group Applied Electrochemistry & catalysis (ELCAT)
The core research goal within ELCAT lies in the development of state-of-the art electrochemical reactors and catalysts, with a view towards large-scale industrial development in the field of industrial electrification, in a green and sustainable way.
WHAT WE DO
In recent years there has been a growing interest in clean and environmentally friendly methodologies in organic synthesis. The complex nature of these organic syntheses arises from the large number of reaction steps, use of auxiliaries and sometimes low selectivity. To tackle these issues, an electrosynthetic methodology can be applied. In the ELCAT research group several electrosynthesis reactions are currently under investigation: the electrochemical aldol condensation, organic halide reductions and intramolecular ring formation reactions .
Electrochemistry allows for a manifold of reactions to proceed easily and on a large scale. However a major drawback of electrochemical activation is the large overpotential required for many of these processes. Reducing those large overpotentials can only be done by improving the catalytic activity. Thus, much attention has been devoted to develop electrocatalytic processes, either by utilizing homogeneous redox catalysts (e.g. metal complexes, aromatic mediators) or by the use of heterogeneous electrocatalytic materials.
In the domain of electrochemical reactor engineering ELCAT focuses on development and optimisation of reactors for the electrochemical synthesis of chemicals (organic as well as inorganic). Investigations in this research domain require a combined approach of know-how on (1) reactor design, (2) electrochemical analysis techniques and (3) electrocatalysis.

calorimetry and safety studies,
Gathering the necessary safety information is indispensable for the development of an industrial synthesis process. This implies the investigation of several aspects:
The electrochemistry expertise and equipment in the ELCAT group is available for third party users. We can consult on a variety of electrochemical phenomena such as corrosion, organic electrochemistry and reaction mechanisms.
It is essential to gather physicochemical parameters when designing an industrial separation process for newly synthesized chemical species. It can moreover be necessary to conduct trial separation runs in semi-industrial or pilot scale equipment in order to test the validity of the design procedures.
