摘要：
Metal-organic Frameworks (MOFs) are promising precursors and templates for the construction of porous micro/ nanostructures. In this work, we prepared a bimetallic MOFs-derived metal oxide Co3O4/In2O3 nanoparticles (NPs) gas sensor by hydrothermal method for the detection of TEA. The composition, microstructure and gas sensitivity of Co3O4/In2O3 NPs were investigated. The results show that Co3O4/In2O3 NPs have excellent response and selectivity to TEA. At 225 degrees C, the response of Co3O4/In2O3 NPs to 20 ppm TEA reaches 365.3, which is 30.2 times the response of the pristine In2O3. The reason for the improvement of the gas sensing performance of Co3O4/In2O3 NPs and the gas sensing mechanism were discussed in detail.
