Title
Nanostruktury grafitizovaného nitridu uhlíku dopovaného nekovovými prvky pro fotokatalytické reakce
Code
GA19-15199S
Summary
Graphitic carbon nitride (g-C3N4) is a polymeric material with extraordinary diamond-like
properties, such as thermal, chemical and photochemical stability and ability to absorb visible
light due to band gap energy of 2.7 eV. However, photocatalytic applications of g-C3N4 are
limited by fast recombination of photoinduced electrons and holes. It can be overcome by
coupling of g-C3N4 with metal and semiconductor nanoparticles or by doping with metals and
non-metals. Another disadvantage is its low specific surface area which can be enlarged by
exfoliation forming nanosheets. In this project, doping of exfoliated g-C3N4 with environmentalfriendly
non-metals, such as S, O, P and N, will be investigated. The resulting materials will be
tested for the photocatalytic decomposition of selected pollutants, such as nitrous oxide, nitric
oxide, acetaldehyde in gaseous phase and Acid Orange 7 and phenol in aqueous phase. The
optimal amount of non-metals in the g-C3N4 nanostructures will be looked for. New properties
of the g-C3N4 nanostructures are assumed to be discovered
