Graphitic carbon nitride is a non-metal photocatalyst easily prepared from nitrogen organic compounds through green synthesis processes that do not require the use of solvents. This work proposes boron to modify layered g-C3N4 structure by incorporating B induce defects aimed at enhancement photocatalytic activity. Boron-modified graphitic has been obtained using elemental and NaBH4 as precurso...

Reinforcing the visible photon absorption and charge separation are key issues to maximize photocatalytic performance of graphitic carbon nitride. Herein, holey bridging-nitrogen-defected nitride nanosheets were prepared through solid-state copolymerization subsequently thermal annealing with melamine hexamethylenetetramine as precursors. Numerous pores bridging nitrogen defects that embedded i...

An ab initio variable-cell-shape molecular-dynamics algorithm is used to investigate the stability of three carbon nitrides with composition C 3 N 4. The hexagonal-C 3 N 4 structure, which has been the subject of earlier investigations , is reened, and its metastability is veriied. Two other metastable structures are identiied: a structure resembling zinc-blende CN with one C vacancy per cubic ...

This work aims to prepare and study amorphous carbon nitride (CNx) films. Films were deposited by reactive magnetron radiofrequency (RF) sputtering from graphite target in argon and nitrogen mixture discharge at room temperature. The ratio of the gas flow rate was varied from 0.1 to 1. Deposited films were found to be amorphous. Highest Nitrogen concentration achieved was 42 atomic percent whic...
