“…Both XRD and Raman results concluded that the synthesized carbon material is more of graphitic nature, which is expected to improve the charge‐transfer rate characteristics of electrode material in delivering good electrochemical performance as graphitic nature enhances the electrical conductivity of carbon material. The N 2 adsorption‐desorption isotherm in Figure 4A clearly exhibits a type IV isotherm, characteristics of mesoporous nature of the carbon material and a slight sharp raise of N 2 uptake at low relative pressure (<0.3 P/Po), reveals the presence of micropores . The specific surface area and pore volume of GPCS carbon material is around 1246 m 2 g ‐1 and 0.86 cm 3 g ‐1 , respectively.…”

Summary Graphitic porous carbon sheets (GPCS), which were synthesized at a low temperature of 900°C by KOH chemical activation technique, possess a specific surface area of 1246 m2 g‐1 with high pore volume. The size of the pores varied in micro‐mesopore regions and exhibited three‐dimensional sheet‐like morphology composed of multilayered graphene sheets with an inter planar distance of 0.360 nm. The GPCS material was tested as anode for Li‐ion battery (LIB) application in half cell mode (vs Li+/Li). The fabricated GPCS electrode shows excellent electrochemical properties in comparison with commercial graphite such as a high discharge specific capacity of 1022 mA h g‐1 after 10 cycles at 100 mA g‐1 and excellent specific capacity retention of 170 mA h g‐1 at a very high current rate of 8000 mA g‐1 and also retains a high capacity of 541 mA h g‐1 after 250 cycles at 500 mA g‐1, which suggests that GPCS material can be a promising electrode for LIB application. A brief comparison with commercial graphite and various carbonaceous materials from literature demonstrated that the GPCS electrode was potential material for high rate LIBs.

“…The degree of graphitization as well as the ordered and disordered structures of mesoporous carbon materials was characterized by Raman spectroscopy. The Raman spectra of the CMK‐8 (x) materials in Figure B exhibit two distinct broad peaks at approximately 1350 and 1590 cm −1 , corresponding to the D band (due to structural defects and partially disordered amorphous carbon) and G band (sp 2 bonded carbon‐carbon stretching), respectively . The I D /I G ratio between the intensities of the D and G bands is normally employed to estimate the degree of graphitization .…”

Three-dimensional ordered mesoporous carbons (OMCs) are desirable for high performing energy storage devices because they provide a continuous electron pathway to ensure good electrical contact and also facilitate electrolyte ion transport by reducing diffusion lengths during charge-discharge process. Here, we report the synthesis of three dimensional mesoporous carbon (CMK-8) using KIT-6 and sucrose as silica template and carbon source, respectively. Initially, KIT-6, synthesized at different hydrothermal temperature (100, 130 and 150°C) is used as silica template to prepare OMCs with different pore diameter. The resulting OMCs were extensively characterized by SAXS, FE SEM, HR-TEM, BET and Raman techniques. The SAXS pattern shows distinct reflections at low 2θ range corresponds to ordered mesoporous structure of cubic Ia3d space group. The OMC possesses a specific surface area of 1017 m 2 /g with a mean pore size of 4.1 nm and large pore volume of 1.14 cm 3 g À 1 . As electrode material for supercapacitor application, the resulting mesoporous carbon delivers a high capacitance of 252 F/g @ 0.5 A/g and shows good rate performance (75% retention in capacitance at high current rates) and outstanding cyclic stability (91% retention after 30,000 cycles). Further, as anode for Li-ion battery application, it also exhibits promising specific capacity (856 mAh/g) with good cyclic and rate capability. The excellent electrochemical properties of the mesoporous carbon material are attributed to its three dimensional porous structure and high surface area with interconnected mesopores that provides rapid ion and electron transport during electrochemical process.

“…In their work Nanaji et al [151] demonstrated that utilizing FA as an alternative source of carbon precursor (for the first time) a smart, efficient and cost-effective methodology employing a modified evaporation induced self-assembly (EISA), strategy was used to synthesise mesoporous carbon (MC), which exhibited excellent textural parameters, employed in super-capacitors. They showed that the resulting carbon synthesised with the modified EISA method exhibited a higher specific surface area with large pore volume and more ordered graphitic carbon.…”

Renewable agricultural biomass derived chemicals, their modifications and uses have seen multiplicity in numerous applications and important processes with major impacts on the pursuit for eco-sustainability. Such applications range include the energy sector, chemistry, pharmacy, the textile industry, paints and coatings, plastic industry, to name but a few. This field of lignocellulosic derived chemicals interconnects several scientific disciplines ranging from agriculture, biochemistry, engineering, environmental sciences, forestry, pharmacy, medicine, etc. hence making it difficult to have a single expert view on these complicated interactions. Therefore, the idea to create a focused review, specifically, on FA (an important furanic compound) is the main objective of this article. FA and its resultant derivatives exhibits an array of capabilities and fascinating properties in various fields of applications. As a compound or with co-reactants, it finds interesting applications as base and/or intermediate chemical compound, hypergolic rocket fuels, in flame resistant composites and coatings used in aerospace, auto, and the built environment; it also finds application as mortars, cementitious grouts, impregnating materials, and sealants due to its exceptional resistance to common corrosive chemicals such as acids, alkalis and other solvents when it is cross-linked. Coupled with its environmental and economic benefits FA has proved to be a remarkable eco-sustainable bio-derived compound.
