Abstract
A porous conductive thin film includes a layer of metal nanoparticles decorated on a layer of conductive carbon nanomaterials. The thin film can be supported by a porous support. The porous support can be a MCE paper upon which a metallic or semi-metallic single-walled carbon nanotube (SWCNT) layer is decorated with gold nanoparticles (AuNPs) or platinum nanoparticles (PtNPs). The thin film can be constructed by filtering a dispersion of SWCNTs onto MCE filter paper followed by the filtration of a citrate stabilized dispersion of AuNPs or PtNPs onto the SWCNT layer.
