HZB-EPFL tandem campaign

2023-09-08T11:00:31+01:00July 7th, 2023|Project News|

The Helmholtz Zentrum Berlin for Materials and Energy (HZB) & the École Polytechnique Fédérale de Lausanne (EPFL) carried out a joint campaign at the High flux solar simulator (HFSS), Lausanne in the first week of June 2023. The experiments served as a demonstration for the integration of the PEC (Photoelectrochemical conversion) reactor of WP1 and the EC (Electrochemical conversion) reactor of WP3 to carry out tandem electrolysis of CO2 to CO and CO to hydrocarbons. The weeklong experimental campaign focused on relating the operational conditions of the individual reactors to the performance of the integrated PEC-EC device across various performance metrics.

Partners at HZB publish "Unintended cation crossover influences CO2 reduction selectivity in Cu-based zero-gap electrolysers" in Nature Communications

2023-09-08T11:19:25+01:00April 13th, 2023|Project News, Publication|

Congratulations to our partners at the Helmholtz-Zentrum Berlin (HZB) for their recent study published in Nature Communications! Gumaa A. El-Nagar, Flora Haun, Siddharth Gupta, Sasho Stojkovikj, Professor Matthew T. Mayer in the Helmholtz Young Investigator Group “Electrochemical Conversion of CO2” saw their paper titled  "Unintended cation crossover influences CO2 reduction selectivity in Cu-based zero-gap electrolysers" published on April 12th, 2023. Within FlowPhotoChem, the HZB partners target the development of new electrochemical pathways to upgrade CO2 to high-value products. Their approach combines the synthesis of new materials based on mixed metal alloys, oxides, nitrides, and sulfides with a detailed in situ study of catalytic activity, product [...]

FlowPhotoChem team members on the move: Knowledge exchange and training

2023-09-08T14:36:11+01:00December 13th, 2021|Project News|

From August 4th through the 6th, 2021, researchers Siddharth Gupta and Dr Gumaa El-Nagar from the Helmholtz Young Investigator Group “Electrochemical Conversion of CO2” at Helmholtz Zentrum Berlin travelled to the University of Szeged in Hungary to learn more about the work being done at the group of Profs. Csaba Janaky and Balázs Endrődi. Siddharth comments, "The primary aim of the trip was to understand the operating procedure used by the group in Hungary for the EC reactor developed by them in conjunction with ThalesNano. This was done with the view to overcome reproducibility challenges within the consortium and enable rapid catalyst [...]
