title: Thin-walled NiO tubes functionalized with catalytic Pt for highly selective C2H5OH sensors using electrospun fibers as a sacrificial template.
abstract: Hollow thin walled NiO tubes functionalized by catalytic Pt were synthesized via nanofiber templating and multilayered sputter-coating of Pt and NiO thin overlayers followed by heat-treatment at 600 °C. Sandwich Pt-NiO-Pt tube networks exhibited superior C(2)H(5)OH sensing response and remarkable selectivity against CO and H(2) gases.
