  • Abstract
    This paper reports on new and surprising experimental data for catalytic film gas sensing resistors coated with nanoporous sol-gel films to impart selectivity and durability to the sensor structure. This work is the result of attempts to build selectivity and reactivity to the surface of a sensor by modifying it with a series of sol-gel layers. The initial sol-gel SiO2 layer applied to the sensor surprisingly showed enhanced O2 interaction with H2 and reduced susceptibility to poisons such as H2S
