“化学方程式”就像甜瓜一样：结构类似于聚(氨基亚氨基)七嗪(利比西瓜)的氮化碳光催化剂(见公式)可以通过双氰胺和巴比妥酸(BA)直接共聚制备。图中显示了增加共聚混合物(箭头)中BA的含量如何将产品的光学吸收进一步扩展到可见光区域，这对太阳能应用是有利的。
" 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.
