论文摘要
鉴于清洁环境,该行业需要通过可持续方法在不同水平的生产和流程上解决多种需求,包括回收或明智地使用生产废物。另一方面,绿色能源的发展和成功需要通过有效,可持续的方法合成的关键材料。本文中,我们使用废物呈现了绿色,简单,易于扩展,快速且高效的合成及其复合材料及其复合材料与AU和AG纳米颗粒使用废物。基于石墨的去角质的FLG合成在存在工业共产力,糖蜜的情况下发生在水中,接下来,在Ag和Au NPS形成期间,这也表明表现出色的还原性能。沉积在FLG上的NP的尺寸减小表明糖蜜和FLG的协同作用,表现出FLG/糖蜜作为金属稳定剂物种的增加作用。 NPS/FLG复合材料2是在存在过氧 - 单硫酸盐(PMS)活化剂的情况下有机污染物(BISA)降解中有效的光催化剂。基于AU/FLG(PVDF)和AG/FLG(PVDF)电极揭示了相对较高的重量电容,即205 FG-1和729 FG-1。提出的方法值得进一步应用于其他分层材料以及其他非拨动的金属系统。
In view of clean environment, the industry needs to address multiple demands at different levels of production and processes via the sustainable approach including recycling or smart use of produced waste. On the other hand, a development and success of green energy requires the crucial materials synthesized via efficient, sustainable methodology. Herein, we present the green, simple, easily scalable, fast, and highly efficient synthesis of few-layer graphene (FLG) and its composites with Au and Ag nanoparticles using a waste. The FLG synthesis based on the exfoliation of graphite occurs in water in the presence of industrial co-product, molasses, which next shows also performant reductive properties during Ag and Au NPs formation. The decreased size of NPs deposited on FLG indicates the synergetic effect of molasses and FLG, exhibiting the add role of FLG/molasses as metal stabilizer species. The NPs/FLG composites 2 are efficient photocatalysts in degradation of organic contaminant, bisphenol (BisA), in the presence of peroxy-monosulfate (PMS) activator. The Au/FLG (PVDF) and Ag/FLG (PVDF) based electrodes reveal as well relatively high gravimetric capacitance, 205 Fg-1 and 729 Fg-1. The presented approach is much worthy to be further applied in the synthesis of other layered materials as well as other non-noble supported metallic systems.
