Abstract

Graphene oxide (GO) is a sp² hybridized carbon atom arranged in a honeycomb lattice. Graphene is a new allotrope of carbon compound which could prime new openings in research fields. GO was successfully synthesized via Phyllanthus Emblica (PE) leaf. Structures, morphologies and photo catalytic activities of the as synthesized nanomaterial were determined by using X-Ray diffraction (XRD), UV-Visible spectroscopy, Field emission scanning electron microscopy (FE-SEM), Energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), High resolution transmission electron microscopy (HRTEM) analysis. The photo catalytic activities of the as-synthesized GO were estimated for the degradation of malachite green (MG) and methyl violet (MV) in aqueous solution under replicated solar light. The photo catalytic degradation of GO was 94% for brilliant green and 99% for methyl violet in 120 min.

摘要

氧化石墨烯 (GO) 是一种 sp ²杂化碳原子排列成蜂窝晶格。石墨烯是一种新的碳化合物同素异形体，可以为研究领域开辟新的大门。GO是通过余甘子（PE）叶成功合成的。采用 X 射线衍射 (XRD)、紫外-可见光谱、场发射扫描电子显微镜 (FE-SEM)、能量色散光谱 (EDS)、傅里叶变换红外对合成的纳米材料的结构、形貌和光催化活性进行了测定光谱（FTIR），高分辨率透射电子显微镜（HRTEM）分析。估计了合成后的 GO 的光催化活性，用于在复制的太阳光下在水溶液中降解孔雀石绿 (MG) 和甲基紫 (MV)。
