This book chapter will describe the recent advancements in advanced carbon-ceramics based hybrid materials, enhanced properties and efficient applications. There are various fabrication methods, Firstly, authors will discuss a solvothermal/hot-pressing method which is employed to fabricate hybrids composed of cross-linked γ-Al2O3 nanorods and reduced graphite oxide (rGO) platelets. After calcination and hot-press processing, monoliths of Al2O3-rGO hybrids are obtained with improved physical properties. It is found that the oxygen-containing groups on graphene oxide benefit to the adsorption of Al-(OC3H7)3 (aluminum isopropoxide), leading to the uniform dispersion of rGO with Al2O3 which is hydrolyzed from aluminum isopropoxide in solvothermal reactions. Further, this research methodology has been extended to another ceramics-graphene nanostructure assembly, i.e., silica-rGO hybrids, by optimizing experimental conditions for the hydrothermal and hot pressing process. This book chapter will be a significant contribution for the applications of ceramics-graphene assembly nanomaterials, which can be made by simple fabrication route and which can be further applied as electrolytes, catalysts, conductive, electrochemically active, and as dielectric materials for the high-temperature applications due to enhanced physical properties.

Ceramic monoliths are applied in many insulating and high resistive engineering applications, but the energy application of ceramics monoliths is still vacant due to less conductivity of monolithic ceramics (for example, in silica- and alumina-based hybrids). This book chapter is a significant contribution in the graphene industry as it explains some novel and modified fabrication techniques for ceramics-graphene hybrids. The improved physical properties may be used to set ceramics-graphene hybrids as a standard for electrical, mechanical, thermal, and energy applications. Further, silica-rGO hybrids may be used as dielectric materials for high-temperature applications due to improved dielectric properties. The fabricated nano-assembly is important for a technological point of view, which may be further applied as electrolytes, catalysts, and conductive, electrochemically active, and dielectric materials for the high-temperature applications. In the end, this chapter discussed porous carbon as a massive source of electrochemical energy for supercapacitors and lithium-ion batteries. Carbon materials which are future of energy storage devices because of their ability to store energy in great capacity, so sustainability through smart materials got a huge potential, so hereby keeping in view all the technological aspects, this chapters sums up important contribution of graphene and porous carbon for applied applications.

In the developing world, energy crisis is the main reason for less progress and development. Renewable and sustainable energy may be of bright future for scientific lagging and low-income countries; further, sustainability through smart materials got a huge potential; so, hereby keeping in view the energy crisis which the developing world is facing for many decades, we are proposing to write a chapter project for obtaining energy through cheap, sustainable, and functional advanced carbon materials. Carbon materials are the future of energy storage devices because of their ability to store energy in great capacity. The graphene is a material with amazing properties like no band gap, which turns graphene a wonderful candidate for use in the photovoltaic. Shortly, this chapter will discuss how superior energy storage may be obtained through various routes like using pyrrolic (N5) and pyridinic (N6) doping in advanced carbon functional materials, or superior energy by KOH activation in carbon materials, or through carbonization in organic matter, respectively. Further, for the advanced carbon functional materials, the superior energy storage using pyrrolic (N5) and pyridinic (N6) doping, or KOH activation, or through carbonization will be discussed one by one for lithium ion batteries, supercapacitors, and relevant energy devices, respectively.

Advance carbon material that includes graphene, fullerenes, hierarchical carbon, and CNTs are referred to as strength of revolution and advancement in the era of material science and technology. In general, 20th century corresponds to plastic meanwhile 21st century will be named as “Century of Graphene” owing to its exceptional physical properties. Graphene is now well-known and prominent 2D carbon allotrope that is considered as multipurpose material in comparison with any material discovered on earth. One of the interesting properties of graphene is strongest and lightest material that enables it to conduct electricity and heat as compared to any other material. Such features permit it to utilize in numerous applications including biosensors, electronic industry, environmental remediation, drug delivery, energy storage, and production as well. Owing to these capabilities, it can be stated that graphene can be utilized to improve effectiveness and performance of existing substances and materials. In the future, conjugation of graphene with other 2D material will be devolved to produce further remarkable compounds that make it appropriate for an extensive variety of applications. This chapter grants the utilization and applications of advanced carbons materials in chemical, polymer, sensing and energy enegineering.

Because of the versatile chemical, physical, and electrical properties, graphene as well as its nanocomposites are regarded as the backbone of engineering and scientific innovation. Different physical and chemical methods are used to create sustainable carbon materials. Furthermore, fabrication methods are employed in order to produce the composites, which are of constituents with desirable properties. Because of their biocompatibility, graphene nanomaterials have enormous potential for improving biology and drug delivery. The proposed chapter provides a variety of fabrication methods for sustainable graphene composites and highlights various applications of graphene. Furthermore, graphene nanocomposites are promising multifunctional materials with improved tensile strength and elastic modulus. Despite some challenges and the fact that carbon nanotube/polymer composites are sometimes better in some specific performance, graphene nanocomposites may have a wide range of potential applications due to their outstanding properties and the low cost of graphene. Because these graphene composites have a controllable porous structure, a large surface area, high conductivity, high temperature stability, excellent anti-corrosion properties, and composite compatibility, they can be used in energy storage as electrocatalysts, electro-conductive additives, intercalation hosts, and an ideal substrate for active materials. Meanwhile, the chapter summaries the graphene nanocomposites requirements for technological innovation and scientific applied research.
