摘要：

A porous thin film of SnO2 prepared on an alumina substrate by using hydrothermally synthesized SnO2 sol shows excellent sensitivity to dilute H2S in air together with good response transient characteristics when calcined at 700-degrees-C. The pore size of the film increases uniformly with calcination temperature, and this well developed porous structure appears to be responsible for the excellent H2S sensing characteristics.
