GRAPHITIC CARBON NITRIDE AS HIGHLY EFFICIENT PHOTOCATALYSTS FOR THE DEGRADATION OF RHODAMIN B

Popis výsledku v původním jazyce

Over the last few decades, because of population growth and rapid industrialisation, contamination such as organic pollutants and heavy metals increased in water resources. Graphitic carbon nitride (g-C3N4), a promising conjugated polymer semiconductor, has been used in many photocatalytic pollutant degradations. However, the bulk form of g-C3N4 is characterised by many defects and its small specific surface area, leading to a decrease in photocatalytic activity.In this work, several exfoliation methods were investigated and compared to the bulk form of g-C3N4. The optical and structural properties of the prepared powder samples were characterised by methods such as scanning electron microscopy, a specific surface analyser, or a UV-vis spectrometer. The photocatalytic activity of the prepared bulk and exfoliated forms for rhodamine B degradation was investigated in a batch reactor. After thermal exfoliation and high-power visible light sources, the time needed for complete degradation of rhodamine B was reduced from several hours to just a few minutes.
