High-Performance Electrocatalysis on Palladium Aerogels

Nanostructures as catalysts: Pd aerogels modified with α‐, β‐, and γ‐cyclodextrins can be obtained by the spontaneous self‐assembly of in situ generated Pd nanoparticles. The Pd aerogels show excellent electrocatalytic activity for the oxidation of ethanol. The catalytic activity is believed to aris...

Zusammenfassung:Nanostructures as catalysts: Pd aerogels modified with α‐, β‐, and γ‐cyclodextrins can be obtained by the spontaneous self‐assembly of in situ generated Pd nanoparticles. The Pd aerogels show excellent electrocatalytic activity for the oxidation of ethanol. The catalytic activity is believed to arise from the nonsupported nanometer‐scale structure of the aerogel network and the interactions of ethanol with the cyclodextrin.
