ABSTRACT

Graphene takes concerned noteworthy consideration payable its distinctive thermal, optical as well as mechanical characteristics. There are several chemical methods are available for reduce graphene oxide (r-GO) towards graphene use by many reducing agent’s alike hydrazine hydrate and its derivatives. Nevertheless, they are highly explosive and emit harmful gases. Reduction of graphene oxide (GO) employing green approaches by way of plants consumes fascinated much devotion by reason of its competence, sustainable structures, and relatively low in price. Though, the crucial constituents in green extracts and their biological degradation determinations regarding GO continue quiet not well unstated. Now present work, the GO was reduced by capsicum annuum (CA) extract. The ideal circumstances for bio reduction existed at volume proportion of chili extract (10 g L⁻¹) and GO (0.5 g L⁻¹) solution aimed at 8 h at 80°C. The r-GO was considered with Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), Field emission scanning electron microscopy (FESEM), X- Ray diffraction (XRD), Thermo gravimetric analysis/Differential thermal analysis (TGA/DTA), Brunauer-Emmett-Teller (BET), and zeta potential. Outcomes inveterate the oxygen-holding clusters in GO were well detached, development of topping coat on the exterior of r-GO, besides virtuous diffusion of r-GO in aquatic medium. The photo catalytic degradation of GO nano composite was 96% for methyl violet (MV) in 60 minutes.

摘要

石墨烯因其独特的热、光学和机械特性而受到关注。有几种化学方法可用于将氧化石墨烯 (r-GO) 还原为由许多还原剂的类似水合肼及其衍生物使用的石墨烯。然而，它们具有高度爆炸性并散发出有害气体。通过植物采用绿色方法减少氧化石墨烯（GO）因其能力、可持续结构和相对较低的价格而引起了人们的极大关注。然而，绿色提取物中的关键成分及其关于 GO 的生物降解测定仍然没有得到很好的说明。现在的工作，辣椒减少了GO(CA) 提取物。生物还原的理想环境存在于辣椒提取物 (10 g L ^-1 ) 和 GO (0.5 g L ^-1 ) 溶液的体积比例，目标是在 80°C 下放置 8 小时。r-GO 采用拉曼光谱、傅里叶变换红外光谱 (FTIR)、场发射扫描电子显微镜 (FESEM)、X 射线衍射 (XRD)、热重分析/差热分析 (TGA/DTA)、Brunauer- Emmett-Teller (BET) 和 zeta 电位。结果在 GO 中根深蒂固的持氧簇被很好地分离，在 r-GO 外部形成了顶涂层，此外 r-GO 在水生介质中的良性扩散。甲基紫 (MV) 在 60 分钟内 GO 纳米复合材料的光催化降解率为 96%。
