2022年1月25日 · Herein, a family of ultrafine metal oxide/reduced graphene oxide (rGO) nanocomposites are synthesized through a heterogenous nucleation and diffusion-controlled growth process for dye...

2024年9月27日 · For the first time, a one-pot synthesis of reduced graphene oxide (rGO) is reported avoiding the use of a post-synthesis chemical or thermal reduction of the graphene oxide that requires further...

2014年8月1日 · The commercial and synthesised few-layer graphene oxide, prepared using oxidation reactions, and few-layer reduced graphene oxide samples were structurally and chemically investigated by the X-ray diffraction (XRD), transmission electron microscopy (TEM) and electron spectroscopy methods, i.e. X-ray photoelectron spectroscopy (XPS) and ...

2023年6月25日 · The morphological characteristics of GO and rGO can be explained using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). SEM is beneficial for the inquiry of structural morphology of the GO, rGO.

Efficient reduction of GO was performed, using cellular extracts of three algal strains. The rGO were characterized by SEM, TEM, UV-Visible spectroscopy, XRD, FTIR, Raman spectroscopy, Zeta...

2015年5月15日 · Here, we report the synthesis of RGO by sonication-assisted oxidation of graphite in a solution of potassium permanganate and concentrated sulfuric acid followed by reduction with ascorbic acid...
