Photocatalytic efficiency of bismuth oxyhalide (Br, Cl and I) nanoplates for RhB dye degradation under LED irradiation

다국어 초록 (Multilingual Abstract)

BiOX (X = Br, Cl and I) nanoplate photocatalysts were synthesized by hydrothermal method. Thephotocatalytic activity of the synthesized catalysts was evaluated for RhB dye degradation under fourtypes of light emitting diodes (LEDs) irradiation possesses different wavelength. 100% RhB dyedegradation was achieved for BiOCl and BiOBr catalysts within 120 and 240 min under UVLEDirradiation. Whereas BiOI catalyst owns 83.4% degradation under red LED (RLED) irradiation at the end of240 min. Our study reveals that BiOI photocatalyst could be effective for RhB dye degradation undercheaper RLED irradiation rather than UVLED.
