Carbon films produced from ionic liquid carbon precursors

Abstract

The invention is directed to a method for producing a film of porous carbon, the method comprising carbonizing a film of an ionic liquid, wherein the ionic liquid has the general formula (X +a ) x (Y −b ) y , wherein the variables a and b are, independently, non-zero integers, and the subscript variables x and y are, independently, non-zero integers, such that a·x=b·y, and at least one of X + and Y − possesses at least one carbon-nitrogen unsaturated bond. The invention is also directed to a composition comprising a porous carbon film possessing a nitrogen content of at least 10 atom %.

What is claimed is: 
     
         1 . A composition comprising a porous carbon film possessing a nitrogen content of at least 10 atom %. 
     
     
         2 . The composition of  claim 1  wherein said porous carbon film is a mesoporous carbon film.
