Abstract

"Chemical Equation Presented" Just like a melon: Carbon nitride photocatalysts (see formula) structurally akin to poly (aminoimino)heptazine (Liebig's melon) can be prepared by direct copolymerization of dicyandiamide with barbituric acid (BA). The picture shows how increasing the amount of BA in the copolymerization mixture (arrows) extends the optical absorption of the products further into the visible region, as is favorable for solar-energy applications.
