Flexible self-powered high-performance ammonia sensor based on Au-decorated MoSe2 nanoflowers driven by single layer MoS2-flake piezoelectric nanogenerator
Abstract
Abstract Smart sensing devices with high reliability and self-powered features are critical in future generation wearable applications. In this paper, we reported for the first time a room temperature Au-MoSe2 composite ammonia (NH3) sensor driven by a novel flexible piezoelectric nanogenerator (PENG) based on two-dimensional (2D) semiconductor MoS2 flake. Moreover, we also demonstrated the MoS2-based PENG device attached to the human body for harvesting diverse body motion energy, demonstrating its strong potential for applications in wearable devices. A series of characterizations of 2D piezoelectric semiconductor MoS2 and Au-MoSe2 sensing materials were carried out. The Au-MoSe2 composite-based ammonia sensor with MoS2 PENG showed a higher response (Va/Vg = 29 @ 100 ppm NH3) toward NH3 than that of MoSe2 counterpart (Va/Vg = 25 @ 100 ppm NH3). And it has superior selectivity and outstanding long-term stability. Moreover, the sensor also has a fast response/recovery time (18 s/16 s) towards 20 ppm NH3. Finally, the enhanced sensing mechanism of Au-MoSe2 composite toward NH3 was discussed by using first-principle calculations based on density functional theory.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
