氧化锌基CO2传感器的性能瓶颈与材料改性
Performance bottlenecks and material modification of ZnO-based CO2 sensors
摘要
Abstract
Zinc oxide(ZnO)-based chemiresistive sensors offer significant advantages for precise CO2 monitoring due to their low cost,fast response,and ease of miniaturization.However,their practical application is hindered by challenges such as strong cross-sensitivity,high operating temperature,and poor long-term stability.This review systematically presents the CO2 gas-sensing mechanism of ZnO,the types of nanostructures,and the corresponding preparation methods,with a focus on the synergistic optimization mechanisms of strategies including element doping,surface functionalization,and heterojunction construction.Research indicates that precise control of synthesis routes and microstructures can optimize the surface activity and electronic structure of the materials,leading to synergistic improvements in sensitivity,selectivity,and stability.Element doping and heterojunction construction provide effective pathways for such synergistic optimization by modulating the band structure and surface activity of ZnO.Finally,this review summarizes the current challenges and outlines future directions,including room-temperature high-performance synergy,adaptation to complex environments,electronic-level mechanistic guidance,new paradigms of multifunctional sensing,and fundamental extreme applications,thereby providing theoretical support and design guidelines for developing highly reliable,low-power and environmentally robust CO2 sensors.关键词
