  • Project Acronym: CuCO2RR
  • Contract: 134/ 2017
  • Contracting Autority: UEFISCDI
  • Contractor: Universitatea din Bucuresti
  • Allocated Funds: 431.900,00 lei
The chief aim of the project at hand is to solve one of the great mystery in electrocatalysis: activity and selectivity of electrochemical reduction of CO2 (CO2RR). This project will focus in-depth on the scientific understanding of the processes occurring in electro- and photo-assisted chemical reduction of CO2 on nanostructured Cu catalysts. The project aims at providing a better understanding of active sites, elucidation of reaction mechanisms. It is expected that these catalysts lower the onset potential of CO2 reduction compared with electrodeposited Cu. The team is a perfect match between young enthusiastic researchers with expertise in electrochemistry, surface science and nanoparticle synthesis and mature academics with an excellent background in project management, teaming up for delivering such an ambitious goal. Being a project supporting excellence, it is expected to promote enlargement and diversification of knowledge, the formation of a new generation of scientists (social role) with a high professional level: 3 PhD students and 1 master students shall work on this project, under the supervision of the experienced senior researchers. Moreover, it is expected that the team will push the CO2RR knowledge beyond the state-of-the-art by producing outstanding research articles: min 2 scientific papers submitted to peer review journals, 2 conference paper/poster and 1 patent application shall be elaborated based on the accumulated knowledge during the implementation of the project.

Phase I Design and construction of the test bench. Synthesis of nanostructured materials. (Deadline 31.12.2021)

During Phase I / 2021, several Cu based structures were tested and characterized using a new photoelectrochemical cell configuration. The obtained materials were characterized from a morpho-structural and physico-chemical point of view using the following methods: atomic force microscopy (AFM), scanning electron microscopy (SEM), UV-Viz and Raman spectrophotometry, electrochemical measurements (cyclic voltammetry, spectroscopy electrochemical impedance). The results obtained demonstrate the potential of these catalysts based on Cu nanostructures for the electrochemical reduction of CO2. In the next stage, studies will be continued to obtain various Cu-based nanostructures through plasma activation processes and optimize the CO2 conversion process.
