Method for producing g-C3N4 film and use thereof

摘要

In order to provide g-C3N4 capable of being simply and easily handled, a g-C3N4 film is produced by heating, as a starting material, a compound represented by X+mYm−, wherein X+ is a guanidium ion or the like ion, and Ym− is an anion, to vaporize the compound or its reactant, and depositing the compound or the reactant over a surface of a base material heated, the surface carrying negative electric charges or having π electrons, so that the compound or the reactant is polymerized on the base material to generate g-C3N4.
