Abstract

In this study, ZnO-Sn2S3 core-shell nanorod heterostructures were synthesized by sputtering Sn2S3 shell layers onto ZnO rods. The Sn2S3 shell layers consisted of sheet-like crystallites. A structural analysis revealed that the ZnO-Sn2S3 core-shell nanorod heterostructures were highly crystalline. In comparison with ZnO nanorods, the ZnO-Sn2S3 nanorods exhibited a broadened optical absorption edge that extended to the visible light region. The ZnO-Sn2S3 nanorods exhibited substantial visible photodegradation efficiency of methylene blue organic dyes and high photoelectrochemical performance under light illumination. The unique three-dimensional sheet-like Sn2S3 crystallites resulted in the high light-harvesting efficiency of the nanorod heterostructures. Moreover, the efficient spatial separation of photoexcited carriers, attributable to the band alignment between ZnO and Sn2S3, accounted for the superior photocatalytic and photoelectrochemical properties of the ZnO-Sn2S3 core-shell nanorod heterostructures.

Tin

Tin Bohr ModelSee more Tin products. Tin (atomic symbol: Sn, atomic number: 50) is a Block P, Group 14, Period 5 element with an atomic weight of 118.710. The number of electrons in each of tin's shells is 2, 8, 18, 18, 4 and its electron configuration is [Kr] 4d10 5s2 5p2. The tin atom has a radius of 140.5 pm and a Van der Waals radius of 217 pm.In its elemental form, tin has a silvery-gray metallic appearance. It is malleable, ductile and highly crystalline. High Purity (99.9999%) Tin (Sn) MetalTin has nine stable isotopes and 18 unstable isotopes. Under 3.72 degrees Kelvin, Tin becomes a superconductor. Applications for tin include soldering, plating, and such alloys as pewter. The first uses of tin can be dated to the Bronze Age around 3000 BC in which tin and copper were combined to make the alloy bronze. The origin of the word tin comes from the Latin word Stannum which translates to the Anglo-Saxon word tin.

Sulfur Bohr ModelThe number of electrons in each of Sulfur's shells is 2, 8, 6 and its electron configuration is [Ne] 3s2 3p4. In its elemental form, sulfur has a light yellow appearance. The sulfur atom has a covalent radius of 105 pm and a Van der Waals radius of 180 pm. In nature, sulfur can be found in hot springs, meteorites, volcanoes, and as galena, gypsum, and epsom salts. Sulfur has been known since ancient times but was not accepted as an element until 1777, when Antoine Lavoisier helped to convince the scientific community that it was an element and not a compound.

Zinc

The number of electrons in each of zinc's shells is 2, 8, 18, 2, and its electron configuration is [Ar] 3d10 4s2. Zinc Bohr ModelThe zinc atom has a radius of 134 pm and a Van der Waals radius of 210 pm. Zinc was discovered by Indian metallurgists prior to 1000 BC and first recognized as a unique element by Rasaratna Samuccaya in 800. Zinc was first isolated by Andreas Marggraf in 1746. In its elemental form, zinc has a silver-gray appearance. It is brittle at ordinary temperatures but malleable at 100 °C to 150 °C.Elemental Zinc It is a fair conductor of electricity, and burns in air at high red producing white clouds of the oxide. Zinc is mined from sulfidic ore deposits. It is the 24th most abundant element in the earth's crust and the fourth most common metal in use (after iron, aluminum, and copper). The name zinc originates from the German word "zin," meaning tin.
