Temperature and Pore Size Dependence on the Sensitivity of a Hydrogen Sensor Based on Nanoporous Platinum Thin Films


Nanoporous Pt thin films were prepared by co-sputtering Cu and Pt, followed by dealloying and coarsening. The size of the pores was controlled by the coarsening temperature. The nanoporous Pt thin films had pores ranging from a few nanometers to 35 nm. A resistance transient method was used to measure the sensitivity of these thin films in different… (More)
