Enhance the applicability of carbon substrates from banana peels combined with g-C3N4 as a photocatalyst for environmental treatment
Abstract
Carbon/g-C 3 N 4 photocatalyst (BC/CN) was successfully prepared by a simple calcination method from carbon precursor (synthesized from waste banana peels) and urea. The activity and stability of BC/CN were evaluated by rhodamine B (RhB) degradation under visible light. The influence of carbon content in the composite on catalytic activity was studied. The results show that the photocatalytic efficiency of the BC/CN composite is higher than that of the g-C 3 N 4 (CN) pristine and the rate constant of the BC/CN-150 sample is higher than the other samples. This shows that BC/CN-150 material has photocatalytic stability under the visible light region. This process will provide new insight into preparing highly efficient g-C 3 N 4 -based photocatalysts.
