摘要:

在超声波催化条件下,构建以TiO2/BiOBr和MoS2为电极的超声催化燃料电池系统,对废水中的污染物罗丹明B(RhB)进行降解。该体系以复合材料TiO2/BiOBr作为阳极,MoS2为阴极,通过控制变量法改变二者催化剂比例、有无曝气条件、光照条件、底物浓度、电阻大小等单一变量研究对RhB的降解性能,对比不同催化剂负载量的降解效果,确定了MoS2和TiO2/BiOBr的负载量最佳比例。研究结果表明,在曝气、自然光条件下,m(TiO2/BiOBr):m(MoS2)为1:5时,超声波辐照120 min后降解率最高达到99.7%。此外,可通过协同半导体材料的催化与压电性能来提高污染物的降解效率。

Abstract:

Ultrasonic catalytic fuel cell system with TiO2/BiOBr and MoS2 as electrodes was constructed under ultrasonic catalytic conditions to degrade Rhodamine B(RhB) in wastewater. With composite materials for the system of TiO2/BiOBr as anode and MoS2 as cathode, some single variable including the proportion of catalyst, with and without aeration condition, illumination condition, substrate concentration, resistance was controlled to study the degradation of RhB performance. Furthermore, by comparing different catalyst load, the degradation effect of MoS2 was determined and the best proportion of TiO2/BiOBr load. The results showed that under the condition of aeration, natural light, TiO2/BiOBr and MoS2 mass ratio is 1:5, the degradation efficiency reached 99.7% after ultrasonic irradiation for 120 min. In addition, this study proved that the degradation efficiency of pollutants could be improved by coordinating the catalytic and piezoelectric properties of semiconductor materials.
