WebAs the temperature increased to 700 C– 800 C, the graphite cages would serve as a building block for CNT formation and growth. Due to the fact that the high temperature may influence the metal species and carbon growth rate, the curved CNTs were bent and formed helical particles. WebThe degree of condensation during the synthesis was found to be playing a prominent role in determining whether the obtained product was melon or g-C 3 N 4 [24]. ... Nickel-doped graphitic carbon nitride developed by Lewalska-Graczyk et al. possess electrocatalytic properties and aid in the electrooxidation of ethanol.
