Abstract

A nanoporous Pd film sensor fabricated on a carbon-coated AAA template has been found to have a unique H₂ sensing performance compared to traditional dense Pd film sensors. Nanostructured Pd materials have been developed to improve H₂-sensing performance, and they have demonstrated a much quicker response to hydrogen gas. There is always a slight drift in the film resistance for nanoporous Pd film sensors in balancing atmosphere of nitrogen. The pyrolytic, carbon-supported, nanoporous Pd film sensor is effective in detecting both dilute and high concentration of H ₂ gas because of its nanoporous, structure-enhanced, H ₂-sensing ability. Various nanoporous H₂-sensitive materials such as Pd, Pt, Ni, and their alloys are expected to work based on the nanoporous-structure enhanced H₂-sensing mechanism.
