Summary: Novel mesoporous heterostructures composed of CdS, PbS, and SnO2 were synthesized via a green and facile treatment, showing enhanced gas-sensing properties for H-2 gas detection. The CdS/PbS/SnO2 sensor exhibited fast response/recovery time, ultralow detection limit, outstanding selectivity, reliable reversibility, and long-term stability, mainly attributed to its large surface-to-volume ratio and numerous heterojunctions for accelerated carrier transfer. This work suggests great potential for ppb-level H-2 gas monitoring in extreme environments.

Summary: In this work, we successfully synthesized two-dimensional and three-dimensional laminated SnO2 nanomaterials decorated with reduced graphene oxide (rGO), which exhibited efficient chemosensing properties for the potent VOC triethylamine (TEA). The hybrid material (rGO/SnO2) possessed a p-n type heterojunction and mesoporous structures composed of self-assembled SnO2 nanoparticles. Due to its unique 3D/2D structures and p-n heterojunction, the material showed enhanced carrier mobility, electron transfer, activation energy, and mass diffusion for chemosensing processes. It demonstrated excellent chemosensing properties for TEA with high response and selectivity at low operating temperatures, and remained stable and operational for 13 days. For instance, its detection limit for TEA was as low as 358 ppb. These attributes make the material a promising TEA chemosensor for practical applications.

Summary: Constructing porous and heterojunction structures within the semiconductor oxide composites is an ideal strategy for developing gas sensing materials, but it is difficult due to grain boundaries. In this study, ZnFe2O4/SnO2 (ZFO/SNO) composite with porous core-shell spheres structure was successfully synthesized by combining pre-synthesized SnO2 nanospheres with ZnFe2O4. The porous ZFO/SNO composite with a Zn to Sn ratio of 1:0.7 showed excellent acetone sensing performance, attributed to its rich heterojunctions, porous structure, and small nanoparticle size.
