Background and Motivation:

The development of sustainable Direct Air Capture technologies is critical to solve the global warming
problem as the increasing the amount of emitted carbon dioxide in the atmosphere is one of the main
factors for more than half of the global warming variance. Therefore, it became the main target of GHG
capture research recently. Thus, fast mitigation of greenhouse gases emissions has been one of the most
urgent scientific problems in the global arena over the last decades. To this end, capturing carbon
dioxide not only from the point source is important but also the trapped one in the atmosphere is quite
urgent and necessary. Direct air capture (DAC) is a carbon dioxide removal technology which separates
CO2 directly from the air using an engineered system. As it is known, the concentration of CO2 in air is
ultra-diluted which makes this technology be challenging especially in presence of high concentrations
of dioxygen and water in air.
My project in IMVT is focused on DAC technology through designing and preparing the module based on
Electro-Swing Adsorption method. Therefore, the module and the test rig is setup to evaluate the
Adsorption – Desorption performance. One of the important factors is the electrochemical behavior of
the electrode such as Charge/discharge cycle and other electrochemical behavior of electrochemical
cell.
This position is aimed at students from the faculties of chemical engineering, electrochemistry and
chemistry, here at KIT.

Tasks:

1. electrode fabrication for CO2 capture and release through using appropriate coating
technique such as dip-coater, inkjet printer and spray coater.
2. characterization: The electrodes shall be characterized for their structure and morphology,
conductivity, adsorption capacity, and electrochemical performance.

Conditions:

- Students of chemical engineering / process engineering / chemistry or electrochemistry
- Language: German or English
Start: by arrangement
