A heteroatom-enriched hybrid material, HPHM, has been synthesized and it was used to demonstrate the role of mass loading in supercapacitor performance.
It is of enormous scientific and practical implication to develop nanozymes, the enzyme-mimicking nanomaterials, to overcome the instability, difficult storage, and high cost of natural enzymes. The field of enzyme...
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
