“…Structures are defined as nanoscale materials; Nanocrystals are divided into different classes such as nanoparticles, nanotubes, nanowires, nanorods, or nano-thin films. The main reason for the focus on this subject is that the substances exhibit unusual properties and functionality in a certain size range, unlike their volumetric structures [7,8]. On the other hand, nanoparticles, which are defined as powders with a size of 100 nm or less, form the basis of nanotechnology due to nanosized materials.…”

Biomass is the general term for organic substances derived from living organisms (plants and animals). Since, biomass is a renewable, sustainable, innovative, low cost and carbon-neutral energy source, the applications of nano-micro particles produced from biomass in electrochemical applications have emerged. A large number of carbon-based materials, such as featured activated carbon, carbon nanotube, C-dots, biochar, hybrid carbon-metal/metal oxide … etc. can be produced from divergent types of biomass. With the growing energy need in the world, supercapacitors have also developed considerably besides the energy generation and storage methods. The supercapacitor is an energy storage system that can work reversibly to provide high energy in a short time. In these systems, electrode structure and surface properties are crucial for energy capacity enhancement. In this sense, electrode modifications with the above-mentioned biomass-based nano-micro structures are widely used in supercapacitor applications.

“…It is mandatory towards high claim from the market area for new hybrid applications and high-performance capacitors. In addition, it requires a high-power device to provide start-up and to change acceleration energy allied with converting into useful electricity [ 23 , 24 , 25 ]. Recently, supercapacitors in the form of electrochemical double layer capacitors (EDLCs) are mainly carbon-based due to their low cost, high electrical conductivity, good chemical stability, and impressive lifespan [ 26 ].…”

Carbon materials are versatile in nature due to their unique and modifiable surface and ease of production. Nanostructured carbon materials are gaining importance due to their high surface area for application in the energy, biotechnology, biomedical, and environmental fields. According to their structures, carbon allotropes are classified as carbon nanodots, carbon nanoparticles, graphene, oxide, carbon nanotubes, and fullerenes. They are synthesized via several methods, including pyrolysis, microwave method, hydrothermal synthesis, and chemical vapor deposition, and the use of renewable and cheaper agricultural feedstocks and reactants is increasing for reducing cost and simplifying production. This review explores the nanostructured carbon detailed investigation of sources and their relevant reports. Many of the renewable sources are covered as focused here, such as sugar cane waste, pineapple, its solid biomass, rise husk, date palm, nicotine tabacum stems, lapsi seed stone, rubber-seed shell, coconut shell, and orange peels. The main focus of this work is on the various methods used to synthesize these carbon materials from agricultural waste materials, and their important applications for energy storage devices, optoelectronics, biosensors, and polymer coatings.

“…Since early human history, wood has been a major source of energy. With increasing time, there has been an ultimate shift to fossil fuels, which accounts for the majority of energy production (Le Quynh et al, 2017;Youse et al, 2019). Incessant globalization and industrialization has led to spike in the utilization of fossil fuel products like petroleum and coal (Touqeer et al, 2020).…”

“…It is mainly focussed on biomass conversion to liquid fuels. To date, biomass has not been extensively used as reliable energy source in comparison to fossil fuels (Le et al, 2017). Identifying biomass feedstock as a raw material is an important task, as it is easily affected by factors such as moisture content and pretreatment processes.…”

Necessity and exploitation of fossil fuel products are implacable in serving the needs of humanity despite being a finite and limited resource. To meet the thrust of energy, biofuels derived from varieties of renewable resources are imperative in fulfilling the demand of renewable fuels on a large scale without creating environmental concerns. Biofuels are inevitably the result of the carbon fixation process which stores chemical energy, ultimately reducing the total amount of carbon dioxide. Different kinds of biofuels like bioethanol, biomethanol, biogas, and biodiesel are derived depending on varieties of feedstock materials. Among these, production of biodiesel augments the progression of clean and renewable fuel. In this review, we have discussed the production of biodiesel derived from various feedstock and using several processes like pyrolysis, direct blending, micro-emulsion, and trans-esterification, with critical discussion focussing on increasing biodiesel production using nanocatalysts. Biodiesel production mainly proceeds through homogenous and heterogeneous catalysis via trans-esterification method. The review further discusses the significance of nanocatalyst in heterogeneous catalysis based trans-esterification for large scale biodiesel production. With the advent of nanotechnology, designing and modification of nanocatalyst gives rise to attractive properties such as increased surface area, high thermal stability, and enhanced catalytic activity. The role of nanocatalysts have been extensively studied and investigated in regard to the increased biodiesel production. Along with the modification of nanocatalysts, we have briefly discussed the physico-chemical properties and the role of the optimization parameters as it plays a pivotal role in enhancing the biodiesel production commercially.
