The members of the p-type semiconducting SrTi 1−x Fe x O 3−δ family of perovskites have been studied as novel materials for hydrocarbon sensor applications. Screen-printed thick film devices are contrasted to thin films prepared by pulsed laser deposition (PLD). In order to enhance sensor specificity towards hydrocarbons, the influence of iron content, x, film thickness and operating temperature in the range from 300 to 500• C has been investigated. In addition, the use of a catalytically active cover layer made of a platinum-doped zeolite has been successfully studied to reduce the influence of species with cross-interference. An initial model explaining the underlying sensing mechanism is proposed.

“…Such structural changes lead to complications for optical characterization and the quality control of TiO 2 films [12][13][14][15][16]. Several dopants, such as Ce and W [17], Cu [18], Nb and Cr [19], Pt [20], etc., have been used to dope TiO 2 . However, few studies of N-Al co-doped TiO 2 films have been reported.…”

“…Many gas sensors based on the metal oxide semiconductor with Ptzeolite filter-TiO 2 have been developed. These sensors exhibit a selective response to hydrocarbons in the presence of CO [38]. Gas sensors of Pd-doped SnO 2 semiconductor covered with zeolitic films (MFI or LTA type) have been prepared and used for detecting different species (methane, propane, and ethanol) at different humidity levels.…”
