WebIt is found that the gaseous FeCl3 molecules at high temperature can diffuse into the graphite interlayer plane to obtain FeCl3-GIH, and the intercalated FeCl3 is then transferred into Fe3O4 nanoparticles under high temperature reduction, which can prop open the graphite interlayer, thus achieving sandwich-like Fe(3)O(4)GIH. In chemistry and thermodynamics, the standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements in their reference state, with all substances in their standard states. The standard pressure value p = 10 Pa (= 100 kPa = 1 bar) is recommended by IUPAC, although prior to 1982 the value 1.00 atm (101.325 kPa) was used. There is no standard temperature.
