Energy harvesting from CO2 emission exploiting ionic liquid-based CAPacitive mixing

Periodic Reporting for period 1 - CO2CAP (Energy harvesting from CO2 emission exploiting ionic liquid-based CAPacitive mixing)

Reporting period: 2021-01-01 to 2022-06-30

In the two publication I have published I have addressed the issue of the fabrication of nanostructured materials suitable for capacitive electrode fabrication with a green approach. Both the papers (DOI: 10.1002/admi.202101046 and DOI: 10.1002/adsu.202100228) focused on the laser-induced graphenization of polimeric surfaces in order to obtain 3D arrangement of 2D material (graphene in this case).
This process and laser-induced graphene in general is really importan since it can be considered:
Direct laser writing process--> no mask or patterning
One step process --> fast
Low temperature --> suitable for flexible substrates
Low cost --> compatible with flexible electronics
Versatile --> many polymers can be used as precursors
These findings encounter the overall objectives described in CO2CAP, in particular the "electrodes fabrication (to achieve Obj 3)", where I have clearly stated that LIG will be investigated during teh project.
The project started in a complicated period of coronavirus pandemic. This entailed delays in carrying out orders for the purchase of instruments and therefore in setting up the laboratories and at the same time limited access for researchers to the infrastructure. Nevertheless we have so far obtained excellent results:
- we have set up the laboratory dedicated to CO2CAP in addition to the laboratories made available by HI
- we advertised the project at the European Researchers' Night 2021 and in an educational seminar for young students
- we have started to create the project website even if it is not yet accessible due to a problem encountered by the IT department of the institution, to be solved by the end of october
- we started the research activities focusing on three strands, namely the development and characterization of materials, the modeling of the phenomenon and the testing of devices. these three aspects of the research perfectly met to synergistically combine the data and thanks to these efforts we were able to publish two papers and bring the results to a conference on three interventions (2 oral and 1 poster).
Considering that what is described in CO2CAP had never been demonstrated in literature, I can now say that I have obtained the results that demonstrate the effectiveness of the project. We have in fact manufactured some electrochmeical cells that show how it is possible to recover energy from the absorption and desorption cycle of CO2 in an ionic liquid. these data have not yet been published but the paper is being written and will be submitted in the next few months.
