The first green reduction of graphene oxide (GO) using cashew leaf extract as biorenewable reducing agents containing water soluble tannins and gallic acid is reported herein. The synthesized rGO has been well characterized by TEM, SEM, XRD, FTIR, Raman, UV-vis spectroscopy, and cyclic voltammetry. A catalytic probe for electro-/chemical reduction of a nitro group into an amino group in an aqueous medium was also performed successfully.

生物启发性的还原氧化石墨烯的空前合成：用于电/化学还原水性介质中硝基的催化探针†

本文报道了使用腰果叶提取物作为含有水溶性单宁和没食子酸的生物可再生还原剂的氧化石墨烯（GO）的首次绿色还原。通过TEM，SEM，XRD，FTIR，拉曼，紫外可见光谱和循环伏安法对合成的rGO进行了很好的表征。还成功地完成了在水性介质中将硝基电/化学还原成氨基的催化探针。
