Synthesis of mesoporous cobalt-doped MoO3 nanoribbons for highly selective detection of triethylamine

Co-doped MoO 3 nanobelts are successfully synthesized as model materials by MOF derivatization method, and the gas sensing performance towards TEA as well as the sensing mechanism are studied. In particular, the MCo-MoO 3 -450 sample exhibits the best TEA sensing performance at 110 °C, with superior anti-interference ability and high sensing response (R a /R g = 361.62, 50 ppm). It is noteworthy that the improvement of TEA sensing performance can be achieved by adjusting the processing temperature to control the Co 2+ /Co 3+ ratio. This work offers a dependable approach for the production of cobalt-doped MoO 3 nanobelts and demonstrates that cobalt doping is a viable tactic for designation of high-performance TEA sensors.
