摘要
通过静电吸附方法,将结构稳定、性能优良的Anderson型多金属氧酸盐(POMs)负载在g-C3N4表面,调节Na6[TeMo6O24]·4H2O(简写为TeMo6)比例制备得到系列TeMo6/g-C3N4纳米材料,通过扫描电镜、傅立叶红外光谱、X射线粉末衍射等手段对纳米片结构及形貌进行基本表征,简单滴涂制备得到湿度传感器,重点对传感器湿敏性能进行系统测试.结果表明,4%TeMo6/g-C3N4湿度纳米传感器对高湿度环境响应迅速,其在75%～95%湿度环境下响应和恢复时间均在2s左右,该类材料在湿度传感领域具有潜在的应用价值.
Abstract
By using electrostatic adsorption method,a series of polyoxometalate/g-C3N4 nanomaterials with the different proportions were fabricated by loading Anderson-type polyoxometalate Na6[TeMo6O24]·4H2O(for short TeMo6)on the surface of g-C3N4,and they were analyzed by means of scanning electron microscopy,Fourier infrared spectroscopy,X-ray powder diffraction,and so on.Then,by simple drop coating method,their humidity sensing properties were tested and studied in detail.The comparison results show that 4%TeMo6/g-C3N4 humidity nano-sensor can respond quickly to high humidity environment.The response time and recovery time of 4%TeMo6/g-C3N4 humidity nanosensor are around 2 s at 75%-95%relative humidity(RH),which provides a promising method to develop polyoxometalate-derived high-performance humidity sensors.
