Název v původním jazyce
On electronegativity of graphitic carbon nitride
Popis výsledku v původním jazyce
The values of electronegativity (n = 101) of graphitic carbon nitride (g-C3N4) found in the literature were calculated as the geometric mean of the Mulliken electronegativities of carbon and nitrogen. They mostly varied in the interval of 4.64e4.77eV but were very different from that of 6.91 eV calculated in this work. In comparison, additional electronegativities of g-C3N4 were calculated from conduction band potentials (ECB) also found in the literature by means of the Butler and Ginley relationship. The obtained results ranged from 3.79 to 4.62 eV with a median of 4.22 +- 0.04 eV (n = 98). It was concluded that g-C3N4 was a material too complex to be characterized by a single value of electronegativity and a single value of conduction or valence band (EVB) potential. The Butler and Ginley relationship, as well as the concept of electronegativity, has not been experimentally verified for g-C3N4 so far, hence, only the direct measurement of ECB or EVB is recommended.
