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.

“…However, these materials are typically synthesized using input materials and techniques that are not necessarily sustainable, requiring highly pure or hazardous input materials, significant energy budgets and complex, expensive equipment [ 27 ]. In the last few decades, there has been a significant push towards replacing expensive input materials with readily available low or negative value biomass, from coffee grounds to sugarcane bagasse, rice husk, poplar wood, palm kernel shell and coconut coir [ 28 , 29 , 30 , 31 ]. In parallel, significant efforts have been devoted to reducing the complexity and cost of the synthesis processes so that they could actually be scaled up, while also enhancing the properties of the resultant materials.…”

“…Heteroatom doping during biomass carbonization and activation, or the creation of composites of graphene or rGO with transition metal oxides (AB 2 O 4 ), e.g., CoFe 2 O 4 , can tune the electron-donor property and electrochemical behavior of the resultant carbon-based materials [ 32 ]. Amongst promising carbon/transition metal oxide composites that can be produced using in situ doping during carbonization, magnetic nanocomposites based on spinel ferrite (MFe 2 O 4 ) are attractive [ 28 , 29 , 30 , 31 , 32 , 33 ], particularly for supercapacitor devices and applications where their removal using an external magnetic field is desirable, e.g., in medical and photocatalytic wastewater treatment [ 34 , 35 , 36 , 37 , 38 ]. Here, the interface between carbon and metallic components [ 39 , 40 ], as well as finely tuned morphology, high specific surface area and high pore volume facilitates contact with fluids, and in doing so prevents particle aggregation and facilitates separation of change carrier species, with the latter two issues being known limiting factors of ferrite materials when compared to e.g., modified TiO 2 and ZnO photocatalysts [ 41 ].…”

Carbon nanomaterials derived from agricultural waste streams present an exciting material platform that hits multiple sustainability targets by reducing waste entering landfill, and enabling clean energy and environmental remediation technologies. In this work, the energy and photocatalytic properties of reduced graphene oxide fabricated from coconut coir using a simple reduction method using ferrocene are substantially improved by introducing metallic oxides flakes. A series of cobalt ferrite rGO/CoFe2O4 nanocomposites were assembled using a simple soft bubble self-templating assembly, and their potential for clean energy applications confirmed. The transmission electron microscopy images revealed the uniform dispersion of the metal oxide on the rGO sheets. The functional group of the as synthesized metal oxide and the rGO nanocomposites, and its individual constituents, were identified through the FTIR and XPS studies, respectively. The composite materials showed higher specific capacitance then the pure materials, with rGO spinal metal oxide nanocomposites showing maximum specific capacitance of 396 F/g at 1 A/g. Furthermore, the hybrid super capacitor exhibits the excellent cyclic stability 2000 cycles with 95.6% retention. The photocatalytic properties of the synthesized rGO nanocomposites were analyzed with the help of malachite green dye. For pure metal oxide, the degradation rate was only around 65% within 120 min, while for rGO metal oxide nanocomposites, more than 80% of MG were degraded.

Carbon and its derivatives such as graphene, activated carbon, and carbon aerogel, with diversity in morphology and structure, large surface area, and high electrical conductivity become ideal candidates in the growing field of energy. To meet the ever‐increasing energy demand and the development of green and sustainable energy sources, the utilization of biomass and industrial wastes as a carbon precursor has attracted great attention. In recent years, several attempts have been transpired to convert biomass sources and industrial wastes into value‐added carbon materials. However, not all reported precursors are suitable for practical energy applications. Furthermore, the lack of correlation between the characteristics of fabricated carbonaceous materials with desired properties for the energy field has dimmed the utilization of these materials in high‐performance energy‐storage devices. The purpose herein is to summarize the latest progress in this field as well as discuss the limitations on the commercialization of these materials along with possible solutions to remedy the drawbacks and improve the electrochemical performance of biomass and waste‐derived carbon materials.
