叉指电极上原位生长ZnO纳米棒阵列室温CO2气体传感器
Room Temperature CO2 Gas Sensor Based on in-situ Growth of ZnO Nanorod Arrays on Interdigitated Electrode
摘要
Abstract
A CO2 gas sensor is presented,which is prepared by in-situ growth of zinc oxide(ZnO)nanorod arrays direct on interdigitated electrodes(IDEs)using a simple water bath method.The in-situ growth of ZnO arrays on IDEs increases the IDE/ZnO interfacial contact area,strengthens interfacial adhesion,and enhances charge-transfer efficiency.The structurally integrated and uniformly distributed nanorod arrays not only increase the specific surface area of ZnO,providing more active sites for CO2 adsorption,but also offer abundant gas transport channels,facilitating the gas-sensing response.The experimental results show that the sensor based on pure ZnO nanostruc-tures exhibits high sensitivity and fast response to CO2 at room temperature.The gas-sensing response reaches 43.02％in a 1 000×10-6 CO2 atmosphere,with response and recovery times of 45.4 s and 11.9 s,respectively.It also exhibits good repeatability,long-term stability,and selectivity,demonstrating strong potential for CO2 monitoring applications.关键词
