Binaphthyl Mediated Low Temperature Synthesis of Carbon Nitride Photocatalyst for Photocatalytic Hydrogen Evolution

Original language description

Metal-free graphitic carbon nitrides are on the rise as polymer photocatalysts under visible light illumination, taking shares in a range of promising photocatalytic reactions, including water splitting. Their simple synthesis and facile structural modification afford them exceptional tunability, enabling the creation of photocatalysts with distinct properties. While their metal-free nature marks a significant step towards environmental sustainability, the high energy consumption required to produce carbon nitride photocatalysts remains a substantial barrier to their widespread adoption. Furthermore, the process of condensation at approximately 550 degrees C typically results in solid yields of less than 15 %, significantly challenging their economic viability. Here, we report on lowering manufacturing conditions of carbon nitride photocatalysts whilst enhancing photocatalytic activity by introducing binaphthyl diamine as a structural mediator. At 450 degrees C in 2 hours, carbon nitride photocatalyst shows a lower bandgap and enables visible light induced hydrogen evolution (194 mu mol h-1) comparable to benchmark carbon nitride photocatalysts. Research in metal-free hydrogen generation using graphitic carbon nitride under visible light is promising but faces high temperature -low yield syntheses. This study introduces a method to synthesize photocatalytic carbon nitrides at 450 degrees C using binaphthyldiamine as a structural modifier, which enhances photocatalytic activity and solid yield by overcoming high energy synthesis requirement. image
