The sensor responses were analyzed by monitoring the electric resistance changes upon the introduction of H2 or CO analytes. The presented properties of Ag/SnO 2NWs can be used for designing efficient and fast photodegradation systems to remove organic pollutants under solar light without applying any external sources of irradiation. The gas sensing properties of the synthesized SiO2/SnO2 core-shell nanofibers were evaluated under dry and humid conditions and compared to practical SnO2 nanoparticles produced by a hydrothermal method. The efficient photocatalytic process is attributed to two phenomenon surface plasmon resonance effects of AgNWs, which allowed light absorption from the visible range, and charge separations on the Ag core and SnO 2 shell interface of the nanowires which prevents recombination of photogenerated electron-hole pairs. The resulting novel SiSnO2 core-shell heterostructures exhibit remarkable synergy in large, reversible lithium storage, delivering a reversible capacity as high as 1869 mA h g(-1)500 mA g(-1) after 100 charging-discharging cycles. To form Fe3O4SnO2 nanocomposites (FeSn-Ox). The rhodamine B and malachite green degraded after 90 and 40 min, respectively, under irradiation at the wavelength of 450 nm. The synthesis and properties of Fe3O4SnO2 core-shell nanoparticles are reported in the present paper. The degradation was investigated by studying time-dependent UV/Vis absorption of the dye solution, which showed a fast degradation process due to the presence of Ag/SnO 2NWs photocatalyst. Rhodamine B and malachite green were respectively selected as a model organic dye and toxic one that are present in the environment to study the photodegradation process with a novel one-dimensional metal/semiconductor Ag/SnO 2NWs photocatalyst. The resultant SnO2C yolk-shell nanospheres possess a hollow highly crystalline SnO2 core (280-380 nm), tailored carbon shell thickness (15-25 nm) and a large void space size (100-160 nm), a high surface area (205 m 2 g-1), a large pore volume (0. AgNWs after coating with a SnO 2 shell change optical properties and, due to red shift of the absorbance maxima of the longitudinal and transverse surface plasmon resonance (SPR), modes can be excited by the light from the visible light region. The synthesis is easy to operate and allows tailoring the carbon shell thickness and void space size. Shaofeng Zhang1,2, Jinggang Hao1, Feng Ren2, Wei Wu2,3 and. Both nanocomposites exhibit high-surface, porous matrices of SnO2.

This study presents core/shell Ag/SnO 2 nanowires (Ag/SnO 2NWs) as a new photocatalyst for the rapid degradation of organic compounds by the light from the visible range. PdSnO2 and SnO2Pd coreshell nanocomposites are prepared via a microemulsion approach. SnO2 core-shell hollow microspheres co-modification with Au and NiO nanoparticles for acetone gas sensing 2020.
