Triazine-based Carbon Nitrides for Visible-Light-Driven Hydrogen Evolution

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)...

Description
Summary: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.
