Recent years have
witnessed many breakthroughs in research on graphene
as well as a significant improvement in the electrochemical synthesis
methods of graphene oxide (GO). GO is a derivative of graphene which
has attracted the focus of worldwide scientists and researchers because
of its hydrophilic and easily functionalized properties. The electrochemical
approach is popular because it saves time, creates zero explosion
risk, releases no hazardous gases, and avoids environmental pollution.
Although recent publications show that the green, rapid, and mass
electrochemical synthesis of GO has more advantages as compared with
the traditional Hummers method, it is crucial to study the effects
of reaction parameters. Herein, we review recent various works regarding
the influences of various reaction parameters on the synthesis of
GO sheets. The advancement, current challenges, and solutions of electrochemical
synthesis methods of GO are also outlined. Through this review, we
hope to spark some clear ideas for anyone who wants to scale up the
yield of GO.
