Abstract

Mesoporous graphite encapsulated Fe3C/Fe nanosheet composites have been synthesized by a facile template free method using ferric nitrate, glycine and glucose as raw materials. X-ray diffraction, transmission electron microscopy, high-resolution transmission electron microscopy and Raman spectrometer have been used to characterize the composites. The formation process and morphology of the products have been discussed in detail. Interestingly, this facile route can synthesize graphite encapsulated Fe3C, Fe3C/Fe and Fe composites with two dimensional nanosheet structure by tuning the reaction temperature and the Fe3C and Fe nanoparticles with size less than 30nm are well dispersed on the carbon sheet. The mesoporous graphite encapsulated Fe3C/Fe nanosheet composites with a high specific surface area have application in non-noble metal electrocatalysis for hydrogen evolution reaction.

See more Iron products. Iron (atomic symbol: Fe, atomic number: 26) is a Block D, Group 8, Period 4 element with an atomic weight of 55.845. The number of electrons in each of Iron's shells is 2, 8, 14, 2 and its electron configuration is [Ar] 3d6 4s2. Iron Bohr ModelThe iron atom has a radius of 126 pm and a Van der Waals radius of 194 pm. Iron was discovered by humans before 5000 BC. In its elemental form, iron has a lustrous grayish metallic appearance. Iron is the fourth most common element in the Earth's crust and the most common element by mass forming the earth as a whole. Iron is rarely found as a free element, since it tends to oxidize easily; it is usually found in minerals such as magnetite, hematite, goethite, limonite, or siderite.Elemental Iron Though pure iron is typically soft, the addition of carbon creates the alloy known as steel, which is significantly stronger.
