Abstract: Disclosed is an application of an ionic iron (III) complex as a catalyst in preparation of a benzylamine compound, that is, an ionic iron (III) complex having a molecular formula of [(RNCHCHNR)CH][FeBr4] (R is tert-butyl) and containing 1,3-di-tert-butyl imidazolium cation is used as a catalyst, di-tert-butyl peroxide is used as an oxidizing agent, and a benzylamine compound is synthesized by oxidation reaction of a toluene/ethylbenzene compound with an aromatic amine. The present invention has a wide application range, and is applicable not only to a toluene compound containing a benzylic primary carbon-hydrogen bond but also to an ethylbenzene compound containing a benzyl secondary carbon-hydrogen bond. This is the first example of the preparation of a benzylamine compound by oxidation reaction of a toluene/ethylbenzene compound and an aromatic amine by an iron-based catalyst.

Abstract: A material and method are provided for increasing catalytic activity of electrocatalysts. In use, a material comprises synthesized carbon-containing composite materials, synthesized metal-metal carbides, and a heterostructure material comprising the synthesized carbon-containing composite materials and the synthesized metal-metal carbides. The synthesized metal-metal carbides are atom-decorated, at least in part, on the synthesized carbon-containing composite material. Additionally, a method of increasing catalytic activity of an electrocatalyst includes dissolving a metal precursor into a first solution, where the metal precursor comprises a set of characteristics. A heterostructure material is created based on the first solution, wherein catalytic activity of the heterostructure material is a function of the set of characteristics, and wherein the heterostructure material includes a metal-metal carbide that is atom-decorated to synthesized carbon-containing composite materials.
