Carbon Foam Decorated with Silver Nanoparticles for Electrochemical CO2 Conversion
Open accessAbstract
Electrochemistry is a promising method to recycle CO 2 into useful carbon feedstock and for storing intermittent renewable energy. To date, Au and Ag nanoparticles are the most active catalysts for electrochemical conversion of CO 2 to CO. However, agglomeration reduces the activity and the high cost slows widespread commercialization. Suitable support materials are thus needed to improve catalyst utilization. We explore carbon foam (CF) as a catalyst support. Compared with carbon black or graphene nanoplatelets, CF has higher surface area, larger pores, and more defects, resulting in improved uniformity of Ag nanoparticle distribution as well as higher activity and efficiency for CO 2 conversion to CO.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
