自支撑Co-MOF/Ti3C2复合柔性薄膜传感器的制备与性能研究
Research on the Preparation and Performance of Self-supporting Co-MOF/Ti3C2 Composite Flexible Film Sensor
摘要
Abstract
Hydrogen detection is of great significance for ensuring energy safety,and two-dimensional(2D)materials have shown great potential in the field of gas sensing due to their large surface area and excellent electrical conductivity.MXene(Ti3C2Tx),as an emerging 2D material,can adsorb hydrogen through its surface oxygen-containing functional groups or surface defects,thereby changing its resistance.However,during the preparation of Ti3C2 thin films,adjacent Ti3C2 layers are prone to stacking due to strong van der Waals forces and hydrogen bonding interactions,which hinders ion transport and reduces the surface area and available active sites.To overcome this challenge,a self-supporting Co-MOF/Ti3C2 composite film was prepared by loading metal-organic framework(Co-MOF)onto Ti3C2.Co-MOF,with its abundant active sites and unique pore structure,not only effectively alleviates the self-stacking of Ti3C2 layers but also significantly increases the specific surface area of the material(up to 274 m2/g),thereby enhancing the adsorption active sites for hydrogen molecules.This composite material combines the high sensitivity of Co-MOF and the high conductivity of Ti3C2,achieving rapid response and high-sensitivity sensing of hydrogen concentration,and exhibiting broad application prospects in the field of hydrogen sensing.关键词
