Synthesis of Three‐Dimensional Reduced‐Graphene Oxide from Graphene Oxide

Abstract

Carbon materials and their allotropes have been involved significantly in our daily lives. Zero-dimensional (0D) fullerenes, one-dimensional (1D) carbon materials, and two-dimensional (2D) graphene materials have distinctive properties and thus received immense attention from the early 2000s. To meet the growing demand for these materials in applications like energy storage, electrochemical catalysis, and environmental remediation, the special category, i.e., three-dimensional (3D) structures assembled from graphene sheets, has been developed. Graphene oxide is a chemically altered graphene, the desired building block for 3D graphene matter (i.e., 3D graphene macrostructures). A simple synthesis route and pore morphologies make 3D reduced-graphene oxide (rGO) a major candidate for the 3D graphene group. To obtain target-specific 3D rGO, its synthesis mechanism plays an important role. Hence, in this article, we will discuss the general mechanism for 3D rGO synthesis, vital procedures for fabricating advanced 3D rGO, and important aspects controlling the growth of 3D rGO.

Design of Porous Graphene Materials from Organic Precursors

“…With these DOI: 10.1002/crat.202200186 exceptional properties, porous graphene has shown great promises for a variety of applications, especially for energy conversion and storage. [6][7][8][9][10] 2D graphene always suffers from re-aggregation problem due to the strong Van der Waals interaction during charge/discharge whereas, porous graphene not only facilitate rapid transport of electrons and ions, but also prevent agglomeration effectively. [11,12] At present, these porous graphene materials were prepared using template or template-free methods, where defects are being introduced in the graphene lattice planes by chemical etching, chemical activation, etc.…”

“…Another important type of nanomaterials are carbon-based nanomaterials and their allotropes play an important role in our daily lives [23]. Graphene (G) and its derivatives have recently attracted a lot of attention due to their extraordinary physicochemical features its unique structure and geometry such as high fracture strength, good thermal and electrical conductivity, high Young's modulus, biocompatibility, rapid charge carrier mobility, and high speci c surface area [24,25].…”

Fabrication of graphene-based porous materials: traditional and emerging approaches

“…With its introduction to the world of materials design, graphene oxide (GO) has attracted enormous attention from researchers across the globe. [6][7][8][9] This two-dimensional (2D) carbon-based, ideally monoatomic nanosheet is decorated with oxygen-containing moieties providing it with appealing properties. 10 Modifying GO into reduced graphene oxide (rGO) can not only tune the surface chemistry of this nanomaterial, but also provide it with the conductivity and electrical properties that are ideal for several applications.…”
