Conductive Metalorganic Framework Chemical Sensors


Technology Description


This technology is a gas sensing device made of a highly oriented metal-organic framework (MOF) material on an oxide substrate. The MOF is also made conductive by the addition of a redox active molecule. The conductive MOF is made without using a gold substrate, and the method of assembling the MOF layers incorporating the redox active molecule improves sensitivity and stability in gas sensing applications.


Features & Benefits


  • High conductivity and sensitivity
  • Simple manufacturing with known materials
  • Oxide substrate




  • Monitoring CO2 in water
  • Geochemical sensing of CO2 and CH4


Background of Invention


Metal Organic Framework (MOF) thin films are porous materials that consist of metal ions connected by organic ligands. They are highly porous and can be used in chemical sensors in a variety of applications and environments. However, most MOFs have low sensitivity. After examining nucleation and assembly mechanisms of the MOF films, researchers at OSU, in collaboration with NETL, have developed a MOF material with dramatically improved conductivity and stability for gas sensing applications.
