摘要
能源和环境挑战是当代社会的关键问题。本研究提出了一种基于 n 型和 p 型硅晶片的新型固液固接触催化(CEC)方法,用于降解亚甲基蓝、罗丹明 B、麦角黑 T 和结晶紫等有机染料。值得注意的是,在室内光照条件下,5 ppm 亚甲基蓝的降解效率在短短 18 分钟的摩擦处理中就达到了 96.25%。我们的研究阐明,催化机理源于摩擦光伏效应诱导的电子跃迁和 CEC 促进的电子转移之间的协同作用。此外,固-液-固 CEC 还具有完全可回收和可重复使用等显著特性,从而为固-液-固 CEC 研究的进步开辟了新的途径。
Contact-electro-catalytic degradation of organic dyes based on solid-liquid-solid friction
Energy and environmental challenges stand as pivotal issues in contemporary society. This study presents a novel solid-liquid-solid contact-electro-catalytic (CEC) approach based on n-type and p-type silicon wafers for the degradation of organic dyes such as methylene blue, rhodamine B, eriochrome black T and crystal violet. Notably, under indoor light conditions, the degradation efficiency of 5 ppm methylene blue can achieve an exceptional 96.25 % within a brief 18-min-friction treatment. Our investigation elucidates that the catalytic mechanism arises from the synergistic interplay between electron transitions induced by the tribovoltaic effect and electron transfer facilitated by CEC. Furthermore, the solid-liquid-solid CEC exhibits remarkable attributes such as complete recyclability and reusability, thereby opening new avenues for advancements in solid-liquid-solid CEC research.
