【摘要】 本文利用一种简单的常压化学气相沉积法在氧化石墨烯基底上制备SnO₂材料。通过改变沉积参数（氯化亚锡溶液浓度和沉积时间）得到了多种形貌的SnO₂微纳米材料。利用SEM,EDS和XPS对其形貌,成分及元素价态进行表征,并对SnO₂材料的催化发光性能进行测试。结果表明,以该材料建立的催化发光气体传感器分别对进样2μL的甲醇,乙醇,异丙醇和丙酮展示了较高的灵敏度,快的响应速度及好的重现性。更多还原

【Abstract】 In this paper,a simple atmospheric pressure chemical vapor deposition（APCVD） method was used to synthesize SnO₂ materials on graphene oxide substrate. Several morphologies of SnO₂ micro/nano materials were obtained by altering the deposition parameters（the concentration of SnCl₂ and deposition time）,which were characterized by SEM,EDS and XPS. The cataluminescence（CTL） properties of SnO₂ materials were explored and the results revealed that the sensor based on SnO₂ materials showed relatively high sensitivity,fast responses and good reproducibility to injection 2 μL of methanol,ethanol,isopropanol and acetone.更多还原
