“…This also contributes to the understanding of the synergy between graphene and mesoporous carbon in energy storage applications. Cheng et al [ 237 ] synthesized mesoporous carbon nanospheres with partial ordering in a simple method using P123 as the only template and amphiphilic carbonaceous materials as precursors (mA CMs). The synthesized mesoporous carbon has a diameter of 30–200 nm, and its voltammetric characteristic graph is nearly rectangular (Figure 21B).…”

In the 21st century, materials science has developed rapidly. Mesoporous carbon is now among the most attractive substances due to its enormous specific surface area, high porosity, and structured pore structure. There are many methods to synthesize mesoporous carbon, among which the template method is widely used because of the variety of templates and synthesis pathways. Mesoporous carbon has been used in many fields. Its good electrical conductivity, lightweight nature, and low price have led to many applications in electrochemistry, such as capacitors, electrodes, and materials for electric vehicles. This work contains a literature overview on the synthesis methods and modification techniques for mesoporous carbon, as well as its application in electrochemistry, which serves as a guide for the future growth of mesoporous carbon research.

“…Additionally, the carbon precursor plays a key role in the preparation of activated carbon. The common carbon precursors (De Gisi et al 2016;Shittu et al 2019) mainly include shell (Zazycki et al 2018;Chao et al 2018;De Lima et al 2019), peel (Nasrullah et al 2019;Rashid et al 2019), halm (Sangon et al 2018;Li et al 2019), straw (Feng et al 2017;Qian et al 2019), sugarcane (Gan et al 2019;Meili et al 2019), coal tar (Cheng et al 2013;Zhang et al 2017), coal pitch (He et al 2016), fly ash (Lin et al 2008), etc. For example, Marrakchi et al (Marrakchi et al 2020) prepared mesoporous and high-surface-area activated carbon using defatted olive cake as precursor, and the adsorption properties for removing methylene blue (MB) were evaluated.…”

The coal tar-based carbon with ultra-high specific surface area was synthesized from coal tar using CaO as template coupled with KOH activation by conventional heating. To utilize the existing pores of the porous carbon, the multilayer adsorption of organic dyes, including Congo red and methylene blue, was tested. Results show that the as-made carbon features with hierarchical structure, which is containing both micropores and abundant mesopores. The CTC 4-900 made with the mass ratio of activator/carbon source at 4 under activation temperature of 900 °C shows an ultra-high specific surface area of 3101 m 2 /g with an average of 2.65 nm. The CTC 4-900 had the highest adsorption capacity for Congo red with the saturation adsorption capacity of 3885 mg/g in a monolayer adsorption due to its large mesoporous surface area. Then, the CTC 4-900 -CR can be used for an effective second-layer adsorption for methylene blue with the saturation adsorption capacity of 931 mg/g. For the third-layer adsorption of Congo red, the CTC 4-900 -CR-MB still shows the excellent adsorption performance with the saturation adsorption capacity of 1001 mg/g due to the electrostatic forces. After several layer adsorptions for different organic dyes, the existing pores of the carbon can be utilized completely, showing that it is an alternative way to regeneration.

“…Pitch, another precursor used to fabricate CNFs, is generally obtained from petroleum asphalt, coal tar, and poly(vinyl chloride), and has a higher carbon yield and a lower cost compared to PAN [32,33]. However, impurities in the pitch must be fully removed to obtain high-performance carbon fibers, leading to a great increase in cost.…”

Carbon nanofibers (CNFs) with diameters in the submicron and nanometer range exhibit high specific surface area, hierarchically porous structure, flexibility, and super strength which allow them to be used in the electrode materials of energy storage devices, and as hybrid-type filler in carbon fiber reinforced plastics and bone tissue scaffold. Unlike catalytic synthesis and other methods, electrospinning of various polymeric precursors followed by stabilization and carbonization has become a straightforward and convenient way to fabricate continuous CNFs. This paper is a comprehensive and brief review on the latest advances made in the development of electrospun CNFs with major focus on the promising applications accomplished by appropriately regulating the microstructural, mechanical, and electrical properties of as-spun CNFs. Additionally, the article describes the various strategies to make a variety of carbon CNFs for energy conversion and storage, catalysis, sensor, adsorption/separation, and biomedical applications. It is envisioned that electrospun CNFs will be the key materials of green science and technology through close collaborations with carbon fibers and carbon nanotubes.
