“…Such ecological and energy problems, including the need to reduce the emission of harmful substances to the environment, have increased interest in new solutions for environmental protection [4,5]. These new solutions are based, among others, on the use of adsorption processes on microporous activated carbons [6][7][8][9][10], which are amorphous carbonaceous materials characterised by a well-developed porous structure and thus a large specific surface area.…”

This paper presents original results from the unique analysis of the porous structure of activated carbons (ACs) produced through the chemical activation of polyethylene terephthalate (PET) and polyacrylonitrile (PAN), as well as from a physical mixture of both polymers. An advanced method of adsorbent surface analysis—more specifically, the new method of numerical clustering-based adsorption analysis regarding the surface heterogeneity, pore geometry and adsorption energy distribution parameters—allowed us to obtain information about the porous structure of the ACs from the synthetic polymers mentioned above. As the results showed, ACs obtained with PAN were characterised by a first adsorbed layer with the highest volume. When the surface heterogeneity, highly desirable in most advanced adsorption processes, is taken into account, the materials with the best surface properties in both potassium carbonate (K2CO3) and potassium hydroxide (KOH) activation processes were the ACs obtained with a mass proportion of PET to PAN of 1:3, which were characterised by a low degree of surface heterogeneity and a first adsorbed layer presenting a relatively large volume.

Plant life has dominated this planet from the beginning of time. With over 82% of biomass (BM) coming from plants, primarily trees, plants are the dominant form of life on Earth. BM represents a readily available, ecologically favorable, and renewable low‐cost carbon source. Its rational disposal has emerged as a critical challenge in modern times due to its widespread generation from farming, manufacturing, and forestry activities. Nanotechnology (NT) has enormous potential for a wide range of BM‐related applications, including BM development, processing technique, modification, and utilization. Richard Feynman, a physicist who later won the Nobel Prize in Physics, presented a discussion in 1959 titled “There's Plenty of Room at the Bottom.” This address was the beginning of the New Theory of Physics, which is NT, where he discusses the potential of NT for manipulating matter at the atomic level. In recent years, there has been a significant surge in interest surrounding carbon nanomaterials (CNMs), specifically carbon nanotubes (CNTs) and graphene. These materials have captured the interest of researchers due to their extraordinary characteristics and widespread applications. Utilizing BM as a source shows great potential in creating functional carbon materials (CMs) due to its sustainability, affordability, and high carbon content. Nowadays, CNMs derived from BM have been a popular area of study. Various structures, synthesis techniques, and widespread applications of CNMs have been documented. Thus, this review provides a detailed overview that outlines the latest technological advancements in the fabrication of BM‐derived CMs. It also studies the production of high‐value‐added CNMs from BM and delves into the utilization of BM‐based CNMs as a precursor for textile wastewater treatment. Furthermore, this study also outlines the progress of BM‐derived CNMs in supercapacitors (SCs), sensors, battery electrode materials, fuel cells (FCs), and E‐textiles, showcasing their pivotal role in advancing sustainable technologies for the future.
