“…A high-voltage electric discharge induces temperatures of the carbon source higher than 3000 K in less than 100 ms, effectively converting carbon feedstocks into turbostratic FG. They successfully leveraged this technology for upcycling of single or mixed plastics (PET, PE, PP, PS, polyvinyl chloride (PVC), polyacrylonitrile (PAN), polyurethane, plastic waste pyrolysis ash) to high-quality graphene. − For example, they recently reported the synthesis of a holey and wrinkled flash graphene (HWFG) in seconds from mixed plastic waste feedstocks . The HWFG was then found to be effective as a Li-metal battery anode, metal-free hydrogen evolution reaction (HER) electrocatalyst, and CO 2 gas adsorption material.…”

Plastic waste triggers a series of concerns because of its disruptive impact on the environment and ecosystem. From the point of view of catalysis, however, end-of-life plastics can be seen as an untapped feedstock for the preparation of value-added products. Thus, the development of diversified catalytic approaches for plastics valorization is urgent. Previous reviews of this field have systematically summarized progress made for plastic reclamation. In this review, we emphasize the design of processes by leveraging state-of-the-art technologies from other developed fields to derive a series of valuable polymers, functional materials, and chemicals from waste plastics. The principles, mechanisms, and opportunities for plastic valorization by leveraging chemical catalytic technologies (thermo-, electro-, and photocatalytic) as well as biocatalytic ones are summarized and discussed, which may provide more insights for the future design of catalytic processes. Finally, the outlooks and perspectives to accelerate progress toward a feasible plastic economy are discussed.

We have evaluated some of the most recent breakthroughs in the synthesis and applications of graphene and graphene-based nanomaterials. This review includes three major categories. The first section consists of an overview of the structure and properties, including thermal, optical, and electrical transport. Recent developments in the synthesis techniques are elaborated in the second section. A number of top–down strategies for the synthesis of graphene, including exfoliation and chemical reduction of graphene oxide, are discussed. A few bottom–up synthesis methods for graphene are also covered, including thermal chemical vapor deposition, plasma-enhanced chemical vapor deposition, thermal decomposition of silicon, unzipping of carbon nanotubes, and others. The final section provides the recent innovations in graphene applications and the commercial availability of graphene-based devices.

“…Recently, a new way of large-scale synthesis of graphene from any carbon source was discovered by a process known as the “flash graphene process” that converts any carbon source, including coal, petroleum coke, bio char, food waste, and plastic waste, into a bulk formation of graphene, termed as “laser-induced graphene” (LIG) . This method of graphene synthesis is very efficient at producing different types of high-quality graphene on a large scale and can be used for commercial synthesis purposes. , The utilization of different coal-based materials for their conversion into graphene derivatives is further discussed in detail in the later sections of this review with their potential in producing high-quality, defect-free graphene with a higher yield.…”

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.
