Nanostructure Engineering and Doping of Conjugated Carbon Nitride Semiconductors for Hydrogen Photosynthesis

Going flat out: Simultaneous modifications of the textural, surface, and electronic structures of a rigid conjugated carbon nitride polymer has been achieved using direct co-condensation of urea and Ph4BNa. This method gives boron-doped carbon nitride nanosheets (see picture) that optimize the capture of light, improve the charge-separation kinetics, and enhance the surface reactivity for hydrogen photosynthesis.
