Since the sensing capability of semiconducting metal oxides was demonstrated in the
1960s, solid state gas sensors based on these materials have attracted considerable …

Volatile organic compounds (VOCs), which originate from painting, oil refining and vehicle
exhaust emissions, are hazardous gases that have significant effects on air quality and …

Abstract Heterostructure ZnO/SnO 2 composites material with a hollow nanostructure was
synthesized by solution method. The obtained products were characterized by X-ray …

A gas nanosensor is an instrument that converts the information of an unknown gas
(species, concentration, etc.) into other signals (for example, an electrical signal) according …

SnO 2–ZnO hetero-nanofibers were fabricated by a facile electrospinning method and
calcination in this study. The SnO 2–ZnO nanofibers were characterized by scanning …

Designing heterostructure materials at the nanoscale is a well-known method to enhance
gas sensing performance. In this study, a mixed solution of zinc chloride and tin (II) chloride …

As one important type of the sensing material, the metal oxide film can realize accurate
detection to the low concentration of ethanol. In this paper, a double-layer nano film was …

This work reports the fabrication of mixed structure of ZnO nanorod on SnO2 thin film via
spray pyrolysis followed by thermal annealing and their gas sensing properties. ZnO/SnO2 …

ZnO-SnO 2 core-shell nanowires (CS NWs) with different shell thicknesses (0–120 nm) were
prepared and their sensing behavior was systematically studied. ZnO-SnO 2 CS NWs were …

This paper demonstrated a hybrid composite of tin oxide–reduced graphene oxide (rGO) for
ppm-level detection of ethanol vapour. A facile and low-cost method of hydrothermal …
