Performance of ZnSnO3/GO composites for TEA gas sensor
ZnSnO3(zinc stannate)belongs to ABO3 type perovskite semiconductor metal oxide.Based on the characteristic of a high operating temperature,ZnSnO3/GO sensor was synthesized by one-step hydrothermal method by combining ZnSnO3 with hand-made graphene(GO),and then compared with ZnSnO3 sensor.The test results showe that the morphology of the two samples is good in SEM.Gas sensitive test results show that the ZnSnO3/GO sensor has a good selectivity for triethylamine(TEA)at 200 ℃,a high response and a low concentration detection limit.
