Many three-phase catalytic reactions are limited by gas-liquid mass translbr. Pre'~aous works have round the transI~er rate to be increased by the presence of fine catalyst particles. Most of the studies concerned active carbon particles m aqueous media This paper inten&s to peint out and to explain

The hydrogen sensitivity of palladium MOS sensors in an oxygen-containing atmosphere is shown to depend on the area of the Pd film, the rate of the gas flow, the total pressure and the type of carrier gas. All observations can be explained by the influence of a limited mass transfer in the gas phase
