- SnO2 gas sensor includes a sensor of the most widely used and developed in the market, but until now it has not been able to produce high sensitivity. Tin oxide is one of the materials used in gas sensor technology. The Hummers method is one of the methods for the synthesis of graphene and graphene oxide. This research was carried out by the hummers process, in the form of tin oxide, which was synthesized by chemical exfoliation, which is a method that uses chemical reagents as graphite reducing agents for the synthesis process. The size of the graphite used is 500 mesh with a variable ratio of Sn and graphite and the variable times of the hummers synthesis process. SEM and XRD are tested. The resulting tin oxide has two size distributions, that are 100 nm < x < micron and x < 1 micron. The average particle size of the W3S1 sample is 615,714 nm and 2,253 microns, the W3S3 sample is 731,833 nm and 3,099 microns, the W3S5 sample is 593,923 nm and 2,149 microns, the W5S1 sample is 465,778 nm and 3,096 microns and 362 W45 microns, W5S5 samples were 452.25 nm and 6.512 microns, W7S1 samples were 644.571 nm and 3.024 microns, W7S3 samples were 574.933 nm and 5.355 microns, W7S5 samples were 539.148 nm and 3.081 microns. The results of XRD analysis showed that multiphase graphite and SnO2, the peak of SnO2 diffraction in the W3S5 2θ sample was 31.7537 and d hkl 2.81573 Å, the W3S3 2θ sample was 31.7537 and d hkl 2.81873 Å, and in the W3S1 sample 2θ is worth 31.7537 and d hkl is 2.81373 Å.
