Abstract
A facile aqueous based method of decorating p-phosphonic acid calix[8]arene functionalized graphene with well-dispersed ultrafine palladium nanoparticles (∼2 nm) has been developed. The electrocatalytic Pd-NP-graphene nano-composite has been incorporated into a functional hydrogen sensing device using a simple drop casting technique on interdigitated electrodes. © 2013 The Royal Society of Chemistry.
