“…Carbon aerogels consist of carbon nanoparticles interconnected in clusters with diameters in the range of 3–20 nm and are normally synthesized by carbonization processes or pyrolysis in an inert gas atmosphere (nitrogen, helium, or argon) at above 600 °C, forming a porous carbon network including both graphitic and amorphous regions with a vast amount of disorder . Carbon gels are being intensively studied − and they have a host of applications. There are a few reports on carbon–carbon aerogels, hydrogels and xerogels, mainly on the type of graphene-containing composites.…”

Carbon−carbon allotropic hybrids and their composites are reviewed. Carbon−carbon hybrids are mainly composed of graphene, graphite, graphene oxide, reduced graphene oxide, carbon nanotubes, carbyne chains, fullerenes and more complex spherical and ring-ike carbon forms, graphene quantum dots, and carbon nanodots. Aerogels and xerogels on their basis are also discussed. Most of these hybrides consist of 3D architectures with either covalent or van der Waals interactions between carbon atoms, possessing unusual properties as compared to their counterparts, because of the simultaneous presence of carbon structures of distinct dimensionality and reactivity. These composites can be prepared by a variety of methods starting from already existing allotropes, or by their synthesis in situ, such as chemical vapor deposition, solvothermal techniques, pyrolysis, ultrasonication in solution, and other liquidphase methods, frequently including redox steps. Current and potential applications of hybrids and their metal-doped composites as supercapacitors, sensors, catalysts, and environmental remediation reactants are described.

“…CXs are generally synthesized from condensation of resorcinol and formaldehyde under base catalyst conditions. [37][38][39][40][41][42][43] They have a relatively large surface area due to their textural pores and good conductivity resulting from their 3D carbonparticle structure. Moreover, the physical properties of CXs (such as pore size and pore volume) can be systematically controlled by adjusting the synthesis conditions.…”

“…Moreover, the physical properties of CXs (such as pore size and pore volume) can be systematically controlled by adjusting the synthesis conditions. [19,20,[40][41][42][43] For these reasons, the application of CXs as active materials for EDLC electrodes has been extensively studied. [32][33][34][35][36][37][38][39] However, CXs are not generally used for commercial EDLC electrodes because resorcinol, a compound that is one of the precursors for CXs, is quite expensive.…”

Low‐Cost Carbon Xerogels Derived from Phenol–Formaldehyde Resin for Organic Electric Double‐Layer Capacitors

In this study, low‐cost carbon xerogels (CXs) are successfully prepared by condensation of phenol and formaldehyde and applied to electrode materials for organic electric double‐layer capacitors (EDLCs). Condensation of resorcinol and formaldehyde is the most commonly used method for the synthesis of CXs because although resorcinol is more expensive than phenol, it has better reactivity with formaldehyde. For this reason, research on the synthesis of CXs derived from phenol–formaldehyde resin is potentially useful for decreasing CX cost. Thus, CXs are synthesized using phenol and formaldehyde while gradually increasing the amount of the catalyst to increase the reactivity between the two compounds. Through Fourier transform infrared spectroscopy and nitrogen adsorption–desorption isotherm analysis, successful synthesis of phenol–formaldehyde CXs is confirmed and it is found that a CX prepared with a phenol‐to‐catalyst molar ratio of 50 (PC_50) exhibits the largest surface area among the prepared CXs. Moreover, PC_50 shows good electrochemical performance as an electrode material for organic EDLCs due to its large surface area. In summary, a low‐cost CX with a large surface area and good electrochemical performance is successfully synthesized as an electrode for EDLCs using a phenol precursor, which offers greater cost efficiency compared to resorcinol.

“…In this context, various carbon materials have been investigated as anodes for LIBs [4][5][6]. Among these materials, carbon xerogels have attracted attention for this application because their chemical, structural, and morphological properties can be tailored [7][8][9]. These xerogels are composed of interconnected nodules which create a three-dimensional framework.…”
