Immobilization of Bi2O3 Particles on Activated Carbon Fiber and Its Photodegradation Performance for Pollutant Dyes

Abstract

A combination of activated carbon fiber and bismuth oxide (Bi2O3) was prepared using a facile, one-step hydrothermal method. The resulting photocatalysts were characterized using X-ray diffraction, scanning electron microscopy, energy dispersive X-ray analysis, FT-IR spectra and BET method. UV-spectrophotometry was employed to measure the decrease in the concentration of rhodamine B, methylene blue trihydrate and reactive black B dyes in an aqueous solution after degradation with the photocatalysts under irradiation with visible light. The results contributes a new material to photocatalytic activity.

“…For photocatalytic hydrogen evolution, the SWGT composite has a semiconductor role that converts sunlight energy into chemical energy under ambient conditions with and without sacrificial atmospheric pressure at room temperature 62 – 66 . In this experiment, methanol was used as the sacrificial reagent that further enhanced the catalytic activity of the semiconductor by providing electrons to consume the photogenerated holes which led the recombination time of the semiconductor to increase.…”
