无机阴离子对光催化燃料电池/过二硫酸盐协同体系影响的研究

Study on the effect of inorganic anions on the synergistic system of photocatalytic fuel cell coupling with peroxydisulfate

本研究通过建立光催化燃料电池/过二硫酸盐(PFC/PS)体系降解活性艳兰染料(KN-R),考察了PFC/PS体系的催化活性及产电效能。结果表明,PFC与PS的耦合可大幅提升KN-R的脱色,处理120 min后,KN-R的脱色率达到99.37%。PFC协同PS体系可以提高电池性能,产生更多电能。与单独PFC相比,其最大输出功率密度(Pmax)从0.0003 m W/cm^(2)增加到0.0012 m W/cm^(2)。水中常见无机阴离子对PFC/PS协同体系降解KN-R及产电性能具有一定的促进作用。

In this study,the catalytic activity and power generation efficiency of the photocatalytic fuel cell technology/peroxydisulfate(PFC/PS)system were investigated for the degradation of reactive brilliant blue dye(KN-R).The results revealed that the coupling of PFC and PS significantly enhanced the decolorization of KN-R.After 120 min of treatment,the decolorization rate of KN-R reached 99.37%.The PFC synergistic PS system exhibited improved battery performance and higher electricity generation.When compared to individual PFCs,the maximum output power density(Pmax)increased from 0.0003 mW/cm^(2) to 0.0012 mW/cm^(2).Moreover,common inorganic anions in water exerted a positive effect on the degradation of KN-R and the electricity generation performance of the PFC/PS synergistic system.
