Welcome to the site of the Laboratory of Chemical & Electrochemical Processes
The Laboratory of Chemical and Electrochemical Processes (LCEP), directed by Professor C.G. Vayenas, belongs to the Department of Chemical Engineering at the University of Patras. The group of Patras is credited with the discovery of the effect of Electrochemical Promotion of Catalysis (EPOC) and has pioneered in the use of solid electrolytes, as an active reservoir of ionic species available to control and enhance the catalytic properties of metal and metal oxide electrodes.
The group has an extended experience in catalytic and electrocatalytic processes, which is shown by almost 10 scientific publications per year in high citation impact journals (Journal of Catalysis, Journal of Electrochemical Society, Journal of Applied Catalysis). The group has more than one hundred publications both on the phenomenology and on the fundamentals of EPOC. Research is also carrying out on the use of fuel cells with alternative fuels for simultaneously generation of electrical power and useful chemicals (‘’chemical cogeneration’’). The group of LCEP has also pioneered recently the use of triode fuel cells where a third auxiliary electrode is used to enhance the anodic or cathodic electrocatalysis. Among latest achievements is the development of the monolithic electropromoted reactor (MEPR) which significantly facilitates the practical utilization of electrochemical promotion of catalysis.
Current research of LCEP:
- Electrochemical Promotion of CO2 hydrogenation to high value chemicals and fuels.
- Triode operation of low and high temperature fuel cells.
- Water electrolysis on novel electrocatalysts
- Preparation and characterization of DSA type anodes for alcohol electrooxidation
