The demand for renewable-energy-based efficient systems is a practical indication to develop sustainable energy nanomaterials for energy storage and conversion to reduce the use of pollution-based nonrenewable energy systems. The use of biomass-derived energy components is a new age for the development of sustainable energy electrode nanomaterials. Among biomass, cotton-based electrodes are more popular, as they are cost-effective and efficient energy materials. Cotton-plant-derived porous or pristine nanocarbons have good textural and morphological properties with high specific surface area, hierarchical porous structure, and large pore volume. The functionalization, addition of active moieties, and easy synthetic routes improve the properties and enhance the performance of various electronic devices. The functionalization of derived materials with a heteroatom perturbs the electrical neutrality of the framework. The incorporation of active sites enhances the surface area and creates defects in the framework. These properties speed up the charge storage and energy conversion reaction for better performance of fabricated devices. This Review gives a detailed understanding and advancements about cotton-derived energy nanomaterial. Also, it gives insight about the key factors affecting the performance of cotton-based electrodes, electrolytes, and other components of energy devices. This Review concludes with the cotton-plant-derived supercapacitor, fuel cell, and battery, with a deep insight into their physicochemical properties. This Review also discusses the role of the active mass of the material used for the different device fabrications, which alters the performance. Further, a deep insight has been provided with a brief discussion of other electronic devices like photovoltaic, triboelectric, and piezoelectric devices based on cotton-derived nanocarbon.

“…Cotton brings good benefits to farmers and planting areas. Cottons are also in great demand for scientific research; because cottons can be applied to the preparation of various materials [2][3][4][5][6][7]. But many byproducts (cotton stalks or leaves) remain in the field, which may create solid waste disposal problems as well as cause pests and diseases to subsequent cotton crops [8].…”

There are plant cuticle and complex cell walls on the outer surface of cotton stalk bark (CSB), which reduce the efficiency of liquid penetration of CSB. To increase the permeability of liquids, these barriers need to be broken. Cellulase can selectively hydrolyze cellulose into glucose, and its action conditions are mild. Therefore, cellulase treatment is one of the excellent ways to break the CSB liquid permeation barrier. This experiment studied the effects of different amounts of cellulase treatment on the enzymatic hydrolysis products and surface of CSB. Scanning electron microscopy (SEM) and nano-CT were used to observe the changes in the microscopic morphology of CSB. Ion chromatography and an ultraviolet–visible spectrophotometer were used to determine the dissolution of CSB. The results showed that the cuticle of CSB treated with cellulase was broken, and the cell wall of phloem fibers became thinner, which increased the accessibility of liquid. The content of monosaccharide and lignin in CSB treatment solution increased with the increase of cellulase dosage. Correspondingly, the proportion of polysaccharides on the outer surface of CSB continued to decline and eventually stabilized. These experimental results can provide a reference for improving the permeability of natural fibers and the subsequent treatment effects of biomass products. Graphical abstract The pretreatment of cotton stalk barks with cellulase destroyed the dense protective structure of cell wall, and the content of monosaccharide and lignin in the treated solution increased with the increase of cellulase dosage.

BACKGROUND Hollow carbon nanospheres (HCNS) were successfully prepared using silica as a template. After that, elemental sulfur particles were grown in situ on the surface of the hollow carbon nanospheres by a solution method to prepare HCNS/S composites. RESULTS The morphology and crystal structure of the samples were characterized by scanning electron microscopy and X‐ray diffraction. The electrochemical performance of the samples was tested by constant charge and discharge, cyclic voltammetry and electrochemical impedance spectra using coin 2032 half batteries. The electrochemical tests indicated that the as‐prepared HCNS/S composites exhibited an initial specific capacity of 1162 mA h g−1 at the current density of 0.2 C. CONCLUSION The electrochemical impedance spectra showed that the as‐prepared HCNS/S composites displayed superior electronic conductivity during electrochemical cycles. The employment of HCNS/S composites is beneficial for the improvement of electrochemical performance of lithium–sulfur batteries. © 2022 Society of Chemical Industry (SCI).
