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 4.64–4.77

Exfoliated g-C3N4 materials were prepared by thermal treatment of bulk materials synthesized from melamine at 4 different temperatures in range from 500 to 600 °C. The exfoliated g-C3N4 synergically increased the photocatalytic degradation of phenol

The TiO 2 /g-C 3 N 4 nanocomposites with the various TiO 2 :g-C 3 N 4 weight ratios from 1:1 to 1:3 were prepared unconventionally by pressurized hot water processing in a flow regime. The parent TiO 2 and g-C 3 N 4 was prepared by thermal hydrolysis

Although the nitrous oxide belongs among three of the most contributing greenhouse gases to global warming, it is quite neglected by photocatalytic society. The g-C3N4 and WO3 composites were therefore tested for the photocatalytic decomposition of N

The nanocomposites of WO3 nanoparticles and exfoliated graphitized C3N4 (g-C3N4) particles were prepared and their properties were studied. For this purpose, common methods used for characterization of solid samples were completed with dynamic light

The synthesis of P-doped graphitic carbon nitride (PCN) by in situ doping via co-pyrolysis of melamine and hexachlorocyclotriphosphazene (HCCP) is being investigated. The amount of HCCP varies between 2 and 40 wt% and the results show continuous enri
