Abstract Tungsten oxide (WO 3), a typical n-type gas-sensing material, has attracted
considerable attention to detect various hazardous gases. Previous studies indicated that …

Graphene quantum dots (GQDs) are 0D materials belonging to the carbon-based family that
present some interesting characteristics of graphene combined with a tunable bandgap …

In this work, novel mesoporous heterostructures composed of CdS, PbS and SnO 2
(CdS/PbS/SnO 2) were synthesized via a green and facile treatment. Interestingly, when the …

Monitoring environmental hazards and pollution control is vital for the detection of harmful
toxic gases from industrial activities and natural processes in the environment, such as …

Hydrogen gas sensors were fabricated using mesoporous In 2 O 3 synthesized using
hydrothermal reaction and calcination processes. Their best performance for the hydrogen …

Metal-organic framework (MOF) based graphene oxide (GO) recently merits of attention
because of the relative correspondence of GO with metal ions and organic binding linkers …

With the increasing requirements from toxic and hazardous gas detection technologies, WO
3-based gas sensors have garnered tremendous interest on account of their low operating …

Due to the increase in demand for hydrogen in several fields, sensors that detect the
presence of hydrogen gas more precisely even at room temperature (30° C) are required for …

Magnetron-based gas aggregation cluster source (GAS) was used to prepare high-purity
CuO (cupric oxide) nanoclusters on top of sputter-deposited thin film of tungsten trioxide …

Abstract Two Co-MOF-74 (Co-MOF-I and Co-MOF–II) were designed for the sensing of H 2
gas. Owing to the high density of Co ions (+ 2 and+ 3 states) located in metal clusters in the …
