HOT Nanoscale Communication
Maboudia and co-workers describe a simple method for decorating graphene with metal nanoparticles. The graphene is grown by a chemical vapour deposition method on a copper substrate, then the copper is used as a reducing agent for the electroless deposition of a noble metal – the authors used gold, platinum, palladium and silver.
The method has the advantages of allowing controlled, reproducible and homogeneous surface coverage.
The authors show that a gas sensor produced using this method is capable of detecting H2S, and they intend to develop the work to produce electrochemical biosensors.
