METAL SUBOXIDE AND METHOD OF PREPARING SAME

摘要

PURPOSE: A manufacturing method of a metal suboxide is provided to synthesize the metal suboxide which has large specific surface area by forming a polymer on the surface of a metal suboxide precursor with reacting an aromatic compound which is substituted to a hydroxy radical and a connection precursor. CONSTITUTION: A metal suboxide has more than 1.5m^2/g of a specific surface area. The metal suboxide includes less than 1 weight% of carbon base on the total weight of the metal suboxide. The metal comprises a transition metal, a post-transition metal, and one selected from a combination thereof. The metal suboxide comprises pore. The manufacturing method of the metal suboxide comprises the following steps. A mixture which includes a metal suboxide precursor (1), aromatic compound which is substituted to a hydroxy radical (3), and a connection precursor is manufactured. The polymer (13') is formed on the surface of the metal suboxide precursor by reacting the aromatic compound which is substituted to a hydroxy radical and the connection precursor. The polymer is heat treated. A carbon is removed from the polymer. In the step of manufacturing the mixture which includes a metal suboxide precursor, aromatic compound which is substituted to a hydroxy radical, and a connection precursor; the connection precursor comprises one selected from C1 to C30 aldehyde, C3 to C30 ketone, and combination thereof.
