LaMnO3/Co3O4 nanocomposite for enhanced triethylamine sensing properties

扫码查看
LaMnO3 modified Co3O4 nanocomposites were prepared by simple hydrothermal method combined with sol-gel method.The gas sensitivity properties of pure Co3O4 and LaMnO3/Co3O4 with different com-posite proportions are compared.It is found that 0.6-LMO/Co3O4 sensor has higher sensitivity to trie-thylamine(TEA)than pure Co3O4 sensor,which is improved by 9.27 times.And the working temperature is reduced from 150 to 130 ℃.Besides,it has excellent gas selectivity and repeatability.The improvement of the gas sensitivity of LaMnO3/Co3O4 sensor may be due to the fact that LaMnO3 is an effective catalyst,and the catalytic performance perhaps is beneficial to improving the sensing performance.In addition,the formation of p-p heterojunctions may be the key factor to improve the gas sensing performance.This work provides a new Co3O4-based gas sensing material for the detection of TEA.
