A novel emulsion polymerization–carbonization method was developed to prepare high-temperature-stable (850°C) gold nanoparticle-doped carbon foams using phenolic resins as a carbon source and HAuCl4 as a gold source and acidic catalyst. As-prepared Au–CFs were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD), N2 adsorption and...
A sensitive and selective electrochemical Pb2+ sensor consisting of a gold-carbon foam/chitosan/gold (Au-CFs/Chit/Au)-modified electrode was prepared. The electrode was synthesized via an oil-in-water emulsion polymerization and carbonization approach. Phenolic resins were used as a carbon source. HAuCl4 was used as a gold source and as an acidic catalyst. Melamine was used as a coordination and coupling...
