“…In 2021, Sun et al , achieved the preparation of sea urchin-like porous polyaniline (PPANI) via chemical synthesis method in saturated solution, and obtained PPANI/MWCNTs retaining the special porous morphology of PPANI via a self-assembly method. 81 Due to the strong π–π interaction between PANI and MWCNTs, stable composite materials can be obtained by self-assembly method. With the formation of porous structures, the specific surface area of PANI and PPANI/MWCNTs is significantly increased.…”

“…It was reported that polyaniline could store up to 6–8 wt % of hydrogen . Porous polyaniline P-PANI facilitates the hydrogen diffusion and reaction kinetics of the hydrogen storage alloys. , Polyacrylamide blending with ammonia borane enables the dehydrogenation of the polymeric composite to occur at a lower temperature with enhanced hydrogen purity . Although hydrogen storage by means of physisorption has some limitations, polymers seem to be very promising materials, owing to their high potential for structural and functional tuning, as well as good thermal and chemical stability.…”

A constellation of technologies has been researched with an eye toward enabling a hydrogen economy. Within the research fields of hydrogen production, storage, and utilization in fuel cells, various classes of materials have been developed that target higher efficiencies and utility. This Review examines recent progress in these research fields from the years 2011–2021, exploring the most commonly occurring concepts and the materials directions important to each field. Particular attention has been given to catalyst materials that enable the green production of hydrogen from water, chemical and physical storage systems, and materials used in technical capacities within fuel cells. The quantification of publication and materials trends provides a picture of the current state of development within each node of the hydrogen economy.

“…More specifically, MWCNTs are still the most promising candidate for developing nextgeneration transparent energy storage and conversion technology [125]. For the first time, Sun et al [126] developed a porous polyaniline/multi-walled carbon nanotube-based Co 9 S 8 (Co 9 S 8 +PPANI/MWCNT) composite that can act as a next-generation electrochemical hydrogen storage device and achieved a discharge capacity value of 689.2 mAh g −1 . Interestingly, the spherical shaped nanoparticle of Pt 2 Ir/MWCNT composite has become a well-balanced bi-functional electrocatalyst, and more specifically a fresh active catalyst surface through electrode materials that play an important role in the development of direct methanol fuel cell applications.…”

Carbon-based nanocomposites have developed as the most promising and emerging materials in nanoscience and technology during the last several years. They are microscopic materials that range in size from 1 to 100 nanometers. They may be distinguished from bulk materials by their size, shape, increased surface-to-volume ratio, and unique physical and chemical characteristics. Carbon nanocomposite matrixes are often created by combining more than two distinct solid phase types. The nanocomposites that were constructed exhibit unique properties, such as significantly enhanced toughness, mechanical strength, and thermal/electrochemical conductivity. As a result of these advantages, nanocomposites have been used in a variety of applications, including catalysts, electrochemical sensors, biosensors, and energy storage devices, among others. This study focuses on the usage of several forms of carbon nanomaterials, such as carbon aerogels, carbon nanofibers, graphene, carbon nanotubes, and fullerenes, in the development of hydrogen fuel cells. These fuel cells have been successfully employed in numerous commercial sectors in recent years, notably in the car industry, due to their cost-effectiveness, eco-friendliness, and long-cyclic durability. Further; we discuss the principles, reaction mechanisms, and cyclic stability of the fuel cells and also new strategies and future challenges related to the development of viable fuel cells.
