Abstract

NO gas sensors based on nanoporous silicate films have been synthesized and evaluated with respect to their quasicrystalline structure. Whereas in the hexagonal assembly the surface layer is impermeable, allowing gas transport only sideways, a cubic phase with 3D isotropically distributed pores is highly suitable for measuring NO concentrations in gas streams (see Figure).
