研究目的
Investigating the photocatalytic degradation efficiency of acidic black 10B in aqueous solution using BaxSr1-xFe0.5Co0.5O3-δ catalysts under different reaction conditions.
研究成果
The perovskite-type BaxSr1-xFe0.5Co0.5O3-δ exhibited excellent photocatalytic properties for the degradation of acidic black 10B under UV irradiation. The efficiency was influenced by irradiation time, photocatalyst dose, initial concentration of acidic black 10B, pH value of the solution, and the amount of H2O2 added.
研究不足
The study is limited to the photocatalytic degradation of acidic black 10B under specific conditions and does not explore the degradation of other dyes or under different environmental conditions.
