Conductive polyaniline (PANI) nanotubes were synthesized by the vapor phase polymerization of aniline monomers using hausmannite Mn3O4 nanofibers as an oxidant. Fibrous Mn3O4 templates with an average diameter of 57nm were prepared by the calcination of electrospun composite nanofibers of polyvinylpyrrolidone and manganese(II) acetate. The enhanced nanotube formation in the presence of H2SO4 was interpreted...
Platinum nanoparticles (Pt NPs) were grown directly on multiwall carbon nanotubes (MWNTs) using a wet chemical reduction process. Gas permeable Pt NP-supported MWNT (Pt/MWNT) electrodes were then formed on microporous PTFE membranes through the vacuum-filtration of a Pt/MWNT solution. The potential use of these electrodes in amperometric hydrogen sensor applications was assessed. Various material...
