Abstract
High surface area SnO2 sensor materials were systematically synthesize
d by a surfactant incorporating method. After calcination at 723 K, a
high BET surface area of 156.8 m(2)/g was obtained. The sensing proper
ties of the high surface area SnO2 material were studied using H-2 as
the probing gas. It is found that a linear relationship exists between
sensor surface area and its sensitivity to H-2. (C) 1998 Elsevier Sci
