Unique gas-sensing properties of semiconducting hybrids that are mainly related to the heterogeneous interfaces have been considerably reported. However, effect on is still unclear, which hinders development in applications. In this work, SnO2–SnS2 were synthesized by oxidation SnS2 at 300 °C with different times and exhibited high response NH3 room temperature. With increasing time, relative concentration interfacial Sn bonds, O–Sn–S, among total species increased first then decreased....

In recent years, there has been increasing interest in synthesis of reduced graphene oxide (rGO)-metal semiconductor (MOS) nanocomposites for room temperature gas sensing applications. Generally, the sensitivity a MOS can be obviously enhanced by incorporation rGO. However, lack knowledge regarding how rGO enhance gas-sensing performances MOSs impedes its Herein, order to get an insight into mechanism rGO-MOS and further improve NiO-based sensors at temperature, rGO-NiO nanocomposite was...

The formation of p–n junctions has attracted much attention for improving the gas-sensing performances in field gas detection. Although heterojunctions with a defined interfacial contact are crucial investigating their roles on properties, design such well-defined been sparse until now. Herein, heterostructure composed {001}-faceted Co3O4 as backbones and Fe2O3 nanorods shells was synthesized using simple hydrothermal method without requirement seed crystals. During reaction, it demonstrated...
