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-TiO2)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(NH3)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-TiO2对10×10-6NH3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NH3的气体敏感机理.
Abstract:
The reduced graphite oxide/titanium oxide (rGO-TiO2) nanocomposite sensitive material was prepared by hydrothermal method using titanium tetraisopropoxide and graphite oxide (GO); Compared with a single rGO, composite sensitive materials exhibit higher response (rGO TiO2 vs. 10 × The response of 10-6NH3 is -0.027, with rGO of -0.007, and better repeatability. In addition, the gas sensitivity mechanism of the composite material to NH3 was analyzed
