Chemical sensor development based on polycrystalline gold electrode embedded low-dimensional Ag2O nanoparticles

- Detection of 4-nitrophenol based on Ag2O nanoparticles using polycrystalline AuE.
- Low-dimensional NPs (dia. ∼20.1 nm) are composed in face centered cubic geometry with ∼4.6442 eV band-gap energy.
- Fabrication of efficient 4-nitrophenol by reliable I-V technique.
- It exhibits higher sensitivity (∼4.740 μA cm−2 mM−1) and lower detection limit (∼0.19 μM).
