摘要

Six kinds of Sn(OH)_4 precipitates were prepared by the chemical precipitation method (liquid-phase), of which the pH values are 3.0 (sample 1), 4.5 (sample 2), 6.0 (sample 3), 7.5 (sample 4), 9.0 (sample 5) and 10.5 (sample 6), respectively. After washed and dried, the Sn(OH)_4 precipitates were first calcined into tin oxide powder. Six kinds of gas sensors were made from the obtained SnO_2 powders. The XRD patterns of all the samples were recorded. The sensing properties of all samples to C_2H_5OH and H_2 gases were measured in different gas concentrations and temperatures, including the sensitivities of all samples, their response and recovery properties. The recovery properties of all samples to C_2H_5OH exhibit the sinusoidal oscillation character.
