Abstract
A porous thin film of SnO2 prepared on an alumina substrate by using h ydrothermally synthesized SnO2 sol shows excellent sensitivity to dilu te H2S in air together with good response transient characteristics wh en calcined at 700-degrees-C. The pore size of the film increases unif ormly with calcination temperature, and this well developed porous str ucture appears to be responsible for the excellent H2S sensing charact eristics.
