Highly efficient ethanol vapour detection using g-C₃N₄/ZnO micro flower-like heterostructural composites

Abstract

Heterostructural g-C3N4/ZnO composites were synthesized through a facile hydrothermal strategy using as-prepared g-C3N4 nanosheets and precursor solutions of ZnO for effective ethanol detection.

Facile synthesis of NiFe2O4-based nanoblocks for low-temperature detection of trace n-butanol

“… 35 The electrons that were captured previously are freed into the Ni/Fe-2 nanocomposite conduction band and recombine with the electron vacancies situated in the valence band ( eqn (7) ). 36 The electron depletion layer's thickness on the Ni/Fe-2 nanocomposite has reduced, causing a decrease in the Ni/Fe-2 sensor resistance when exposed to n -butanol. The potential gas detection mechanism for the Ni/Fe-2 sensor is illustrated in Fig.…”
