摘要 利用四异丙醇钛和氧化石墨(GO),采用水热法制备了还原氧化石墨烯/氧化钛(rGO-TiO_2)纳米复合敏感材料,通过傅里叶红外(FTIR)和紫外可见光谱(UV-vis)对复合材料结构进行了表征.气敏特性结果表明,复合敏感材料对氨气(NH_3)具有良好的室温响应-恢复特性;与单一的rGO相比,复合敏感材料表现出更高的响应(rGO-TiO_2对10×10^(-6)NH_3响应为-0.027,rGO为-0.007)和更好的重复性.此外,还分析了复合材料对NH_3的气体敏感机理. The reduced graphene oxide （rGO）-TiO2 composite sensitive materials were fabricated through hydrothermal method by using titanium isopropoxide and GO. The structure of composite was characterized by UV-Vis spectroscopy and the Fourier transform infrared spectroscopy （FTIR）. The response results showed rGO-TiO2 composite sensor performed better response values （ -0. 027） and repeatability to 10 ppm NH3 than that of rGO sensor （-0.007） at room temperature. Moreover, the sensing mechanism of composite sensor was studied.
