“…Double-layer graphene generally has a finer peak structure because the distance between the two graphene layers is shorter. 43,44 The XRD patterns of Pt and Pt-G powders are shown in Figure 2b. As can be seen in Figure 2b, the XRD pattern of Pt powder is dominated by peaks located at 39.80°( 111) and 46.28°(200).…”

Graphene and related materials (graphene oxide, reduced graphene oxide) as a subclass of carbon materials and their composites have been examined in various functions as materials in supercapacitor electrodes. They have been suggested as active masses for electrodes in electrochemical double-layer capacitors, tested as conducting additives for redox-active materials showing only poor electronic conductivity, and their use as a coating of active materials for corrosion and dissolution protection has been suggested. They have also been examined as a corrosion-protection coating of metallic current collectors; paper-like materials prepared from them have been proposed as mechanical support and as a current collector of supercapacitor electrodes. This entry provides an overview with representative examples. It outlines advantages, challenges, and future directions.

“…In addition to their utilization as electrode materials in energy storage devices, graphene is also applicable for energy conversion as well as energy generation purposes. ,,, In devices like fuel cells (FCs) and dye-sensitized solar cells (DSSCs), graphene plays an important role in the efficient conversion of chemical/solar energies into electrical energy. In FCs, graphene derivatives were suitably applied for decreasing the loading of Pt-based catalysts, as a catalyst support/standalone catalyst, or as an electrolyte membrane with the similar performances to that of other materials. − In the case of dye-synthesized solar cells, graphene derivatives were found to be improving the efficiency as well as stability of DSSCs by employment at the photoanode, electrolyte, and the counter electrode. − As these energy converting/harvesting devices utilize the expensive and limited Pt-based catalysts, the use of graphene derivatives as an alternative as well as supportive material not only reduces the cost but also acts as a viable replacement with accepted performance and stability.…”

In the last decade, there has been a phenomenal development in the commercially viable, large-scale synthesis of graphene, a multifunctional advanced carbon nanomaterial, which is gaining popularity for its diverse range of applications, especially in energy storage, composites, sensors, and membranes. With the increasing demand, a large number of worldwide research efforts have been employed, resulting in a series of enormous breakthroughs both in its fundamental science and innovative applications. The earlier reviews on graphene show that the increase in the production yield is often accompanied by the generation of substandard graphene quality, making the process unsuited for commercialization. However, recent studies on graphene synthesis have shown the use of naturally available carbonaceous sources for the production of low-cost graphene derivatives is becoming an emerging trend in graphene research. In this present review, the most recent advances in the synthesis of high-quality graphene from solid carbon precursors, particularly abundant coal, biomass, and waste materials, have been extensively discussed along with their potential scalability for commercial production. The quality and yield of these graphene derivatives synthesized through different methods like chemical vapor deposition, exfoliation, laser-induced, microwave irradiation, and chemical methods are also examined to determine the best-suited synthetic methodology from the available literature. The utilization of graphene derivatives in the energy sector was further discussed, particularly in the emerging field of energy storage. Finally, the challenges and future prospects of this study are highlighted to have a better understanding of the current graphene production scenario, with an insight into the most efficient method for synthesizing high-purity low-cost graphene and their potential for scaleup and energy applications in the distant future.
