Abstract
Multiwall carbon nanotubes (MWCNTs)-supported palladium (Pd) nanocubes (NCs) with the assistant assistance of reduced graphene oxide (RGO) were synthesized via a simple chemical method to fabricate a foldable hydrogen (H2) sensor. Pd NCs were synthesized by a two-step chemical route (seed-mediated growth). Highly uniform colloidal Pd NCs with an average size of 70nm were simply decorated onto the MWCNTs-RGO network assembled on nylon filter membrane by filtration method. The resulting composite was consider as a novel H2 sensing material, which showed a high response, a good selectivity as well as an excellent mechanical stability at room temperature. Furthermore, the fabricated sensor exhibited a broad detection range from 10–10,000ppm with a good linearity behavior. Moreover, the new H2 sensor showed two-fold higher response than our previously reported Pd NPs–Gr hybrid.
