摘要:
采用原位化学氧化聚合法合成了聚苯胺-多壁碳纳米管复合材料,成功构建了修饰生物阴极型微生物电解池,通过聚苯胺-多壁碳纳米管复合材料的耦合作用,提高体系产氢性能,并通过对外加电压、电极间距、电解质浓度等外部操作参数的优化,进一步提高体系性能。实验结果表明,修饰生物阴极实现同步处理废水产氢,表现出优于未修饰生物阴极(MEC)的性能。在外加电压0.9 V、电极间距3 cm、电解质浓度100 mmol/L操作条件下,体系性能最佳。此时聚苯胺-碳纳米管修饰生物阴极微生物电解池H2产率可达0.83 m3/(m3·d),COD去除率为89.3%,阴极H2回收率为51%。
Abstract:
Polyaniline-multiwalled carbon nanotubes were synthesized by in situ chemical oxidation,and microbial electrolysis cells(MEC)with a biocathode modified by polyaniline-multiwalled carbon nanotubes were successfully constructed.The hydrogen production was improved by the coupling effect of polyaniline-multiwalled carbon nanotube. The operating parameters,including the applied voltage,the electrode spacing and the electrolyte concentration were optimized. The results showed that hydrogen production and wastewater treatment were simultaneously achieved in the system and the modified biocathode exhibited better performance than original biocathode did.The hydrogen yield reached 0.83 m3/(m3·d),COD removal rate was 89.3% and cathodic hydrogen recovery was 51%,with the applied voltage 0.9 V,electrode spacing 3 cm, and phosphate buffer solution(PBS)concentration 100 mmol/L.
