UAntwerpen: Department of Applied Electrochemistry and Catalysis (ELCAT)

General expertise of the research group

The core research activities within ELCAT are related to the development of state-of-the art electrochemical reactors and its components, with a view towards large-scale industrial development in the field of industrial electrification, in a green and sustainable way to ultimately replace the traditional chemical  rocesses. The scope there is to improve controllability, flexibility and energy efficiency of the reactions through electrocatalyst and reactor design. This research can thus be subdivided in three main topics, which are interrelated: (i) electrocatalysis, (ii) electrosynthesis and (iii) electrochemical reactor engineering. From those research topics, two major aspects of the identity as a group clearly come to the surface: (1) industrial application and (2) sustainable chemistry. Specific hydrogen- related expertise & research topics

Spcific hydrogen-related expertise & reserach topics

• (Photo-)electrochemical production of hydrogen with a focus on component and reactor development, in-house developed flow-electrolyzers (alkaline and proton-exchange)
• Hydrogen evolution going from catalyst development through GDE preparation and reactor development, with a focus on novel 3D electrodes to improve reactor hydrodynamics (e.g. bubble release, mass transfer, etc.)
• Strategic collaborations already ongoing in the field of alkaline and PEM electrolysis with industry including Agfa and Engie.
• Electrochemical production of formic acid and other CO2-derived chemicals as potential hydrogen carriers, utilizing renewable energy

Available equipment/tools:

• A wide range of electrosynthesis set-ups going from batch cells to flow-cells in combination with advanced potentiostats, including boosters required for achieving higher currents.
• Electrocatalyst synthesis equipment for wet chemical and electrodeposited catalyst manufacturing: atmosphere-controlled oven, elevated temperature and cryogenic synthesis cells, spray coating, rotavap, hydrostatic pressure vessels, TGA, etc.
• All analytical equipment, including (in-line) GC, HPLC, ICP-MS, DEMS, UV-VIS, etc. to determine the reaction performance and product outcome.
• Necessary pumps and sensors (e.g. pressure, flow, pH) to monitor all operating conditions.
• Explosion-safe oven to allow operation at elevated temperatures.
• Additionally, ELCAT possesses the required equipment to develop optimized electrolyzers at different scales (from 1 cm² to 200 cm²). It can count on its own MP 45, ISEL milling machine, highend 3D metal and polymer printers, an accurate 3D laser micromachining setup, a sputter coater and an automated spray coater (up to 1 m² active area).
