Tăng cường khả năng ứng dụng chất nền carbon từ vỏ chuối kết hợp với g-C3N4 làm chất quang xúc tác xử lý môi trường

Abstract

Carbon/g-C₃N₄ 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-C₃N₄ (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-C₃N₄-based photocatalysts.
