A new dimension: The doping of amorphous poly(triazine imide) (PTI) through ionothermal copolymerization of dicyandiamide with 4-amino-2,6-dihydroxypyrimidine (4AP) results in triazine-based carbon nitrides with increased photoactivity for water splitting compared to crystalline poly(triazine imide) (PTI/Li(+)Cl(-), see picture) and melon-type carbon nitrides. This family of carbon nitride semiconductors has potential as low-cost, environmentally clean photocatalysts for solar fuel production.
一个新维度
通过二氰胺与 4-氨基-2,6-二羟基嘧啶（4AP）的离子热共聚，对无定形聚三嗪亚胺（PTI）进行掺杂，得到的三嗪基碳氮化物的光催化分解水活性比晶态聚三嗪亚胺（PTI/Li(+)Cl(-)）和瓜型碳氮化物更高。该系列碳氮化物半导体具有作为低成本、环境友好型光催化剂用于太阳能燃料生产的潜力。
