A graphite-like carbon nitride (g-C3N4) nanosheet sample was synthesized from a melamine precursor by a method of simple direct heating in a semi-closed system followed by thermal oxidation etching at 550 °C for 12 h.
The sample was labelled as (g-C3N412h) and was systematically characterized.
Moreover, the results were then compared with a pristine g-C3N4 sample for the degradation of Bisphenol A (BPA) present in water.
Bisphenol A (BPA) is an endocrine disruptor.
It is known that the BPA is one of the most harmful organic materials and that it does not degrade easily in the environment.
It was therefore selected as a target to test the photocatalytic activity of prepared carbon nitride nanosheets under direct solar irradiation.
The results showed the structure of the g-C3N4 nanosheets when the sample had been treated for a longer time compared to the regular treatment time.
The optical band gap results remained the same, indicating the existence of a g-C3N4 backbone structure.
However, the XPS and FTIR spectra showed some modification on g-C3N4 after longer etching treatment time such as the C-H, CO and N pyridinic structure.
The photocatalytic degradation of Bisphenol A by the g-C3N4 nanosheets under solar irradiation was much better (around 60%) than that with the g-C3N43h bulk sample (around 30%).
This enhanced photocatalytic activity can be attributed to multiple factors such as the smaller particle size, rich carbon surface and high surface area exhibited by the g-C3N4 nanosheets.
This further indicates that g-C3N4 can be used with solar irradiation to treat wastewater containing endocrine disruptor chemicals.
