Program: Study on the gas sensing performance and mechanism ofnickel cobalt oxide-based micro-nano materials toward n-butanol


1.Regulating microscopic surfaces andstructures to boost n-butanol sensing

performances in NiCo2O4/NiOcomposites

NiCo2O4 microsphereshave been fabricated and are subjected to different concentrations of NaBH4treatment assisted by water bath. The NaBH4 reduction treatmentetches crystal structures, breaks metal oxygen bonds, increases vacancy oxygen,dislocation density and specific surface area, reduces crystallite size, andforms NiCo2O4/NiO heterojunction, which significantlyenhances gas sensing properties of the treated NiCo2O4/NiOheterojunction toward n-butanol gas.

2.Incorporating alkalized Ti3C2TxMXenes to advance room temperature n-butanol gas sensing of NiCo2O4nanosheets

Pristine NiCo2O4nanosheets are synthesized by the facile hydrothermal-annealing strategy, butdo not present any gas sensing behaviors at room temperature due to excessivelyhigh baseline resistance in air. Alkalized Ti3C2TxMXenes are introduced to enable NiCo2O4 nanosheets toachieve room temperature gas sensing. The as-prepared NiCo2O4@alkalizedTi3C2Tx (NCO@Alk-Ti3C2Tx)demonstrates superior room temperature sensing properties toward n-butanolgas.
