Apstrakt

A great deal of interest is directed towards g-C3N4 (CN) for the photocatalytic reduction of Cr(VI), due to its high stability in acidic conditions and medium band gap (~2,7 eV), but its practical application is limited because of the high recombination rate of electrons and holes. Sulfuric acid treatment is considered as one of the methods for optimizing properties of CN by certain surface and possibly structure modifications which would lead to an increased specific surface area (Sp) and more active sites, anchoring electronegative groups to enhance charge separation, exfoliated bulk CN into the nanosheets, etc. The aim of this research was to investigate the influence of H2SO4 concentration and other experimental conditions (temperature and time) on physicochemical properties and photocatalytic efficiency of CN.
