CLUE Partner Presented Poster at ECS Meeting Gothenburg

CLUE Partner, Thi Hong Trang Nguyen from K U Leuven, presented a poster at the ECS meeting held at Gothenburg, Sweden on 22nd December 2023 under the title of “Gas-phase Pd Clusters-Modified Mesoporous Copper Oxide Hollow Spheres as Electrocatalysts for CO2 Reduction to Ethylene”.

The poster was about the inculcation of cluster beam deposition (CBD) technology to produce novel electrocatalysts which can increase the selectivity of electrochemical CO2 conversion to C2+ products. As CBD is a versatile technique that allows the deposition of virtually any type of well-defined cluster on a large variety of support, this work provides an attractive avenue to achieve stable, selective multicarbon products via rational electrode design.

This work mainly focuses on mesoporous oxygen-rich copper hollow spheres prepared by a colloid templating method, whose surface is uniformly modified by the deposition of different loadings of well-defined Pd clusters of ca. 3 nm diameter using the laser ablation cluster beam deposition (CBD) technology.

Primary electrochemical results show that these electrodes can reduce CO2 to ethylene with a faradaic efficiency of more than three times higher than that of commercial Cu2O nanoparticles under the same reaction conditions.
