Scholarcy highlights

  • A novel carbon nitride compound, structurally related to the proposed graphitic phase of C3N4, has been synthesized in a bulk well-crystallized form
  • The Altmetric Attention Score is a quantitative measure of the attention that a research article has received online
  • X-ray and electron diffraction measurements on the yellowish compound indicate a hexagonal space group with cell parameters of a = 8.4379(10) Å and c = 6.4296(2) Å. This new compound possesses a two-dimensional C6N9H3 framework that is structurally related to the hypothetical P6m2 graphitic phase of C3N4, but with an ordered arrangement of C3N3 voids
  • The large voids in the graphene sheets are occupied by chloride ions with an equivalent number of nitrogen atoms on the framework protonated for charge balance
  • The composition of the sample was determined by bulk chemical analysis and confirmed by electron energy loss spectroscopy
  • This work represents the first bulk synthesis of a well-characterized and highly crystalline material containing a continuous network of alternating carbon and nitrogen atoms
