Highly Sensitive Room-Temperature Detection of Ammonia in the Breath of Kidney Disease Patients Using Fe₂Mo₃O₈/MoO₂@MoS₂ Nanocomposite Gas Sensor.

ABSTRACT: A novel Fe₂Mo₃O₈/MoO₂@MoS₂ nanocomposite is synthesized for extremely sensitive detection of NH₃ in the breath of kidney disease patients at room temperature. Compared to MoS₂, α-Fe₂O₃/MoS₂, and MoO₂@MoS₂, it shows the optimal gas-sensing performance by optimizing the formation of Fe₂Mo₃O₈ at 900 °C. The annealed Fe₂Mo₃O₈/MoO₂@MoS₂ nanocomposite (Fe₂Mo₃O₈/MoO₂@MoS₂-900 °C) sensor demonstrates a remarkably high selectivity of NH₃ with a response of 875% to 30 ppm NH₃ and an ultralow detection limit
