“…The advantages of OMCs over conventional activated carbons are related with the ordered and hierarchical pore network, but their multi-step preparation procedures are time consuming, use hazardous chemicals to remove the inorganic templates and, consequently, have very low atomic economy and high production costs. This class of nanostructured materials is out of the scope of the present chapter since the first works were published in the late 1990s, and comprehensive reviews are available in the literature, providing a broad overview and up-to-date information on synthesis and properties of this class of porous carbon materials [37][38][39]. In the following, the recent developments regarding new synthesis approaches-i.e.…”

Activated carbons are key materials in technological applications of multidisciplinary fields (e.g. adsorption, separation, and catalytic processes). The extensive use of these materials results from the combination of a well-developed pore network (micropores or micro + mesopores) along with the presence of heteroatoms (e.g. oxygen, nitrogen, and sulfur). The large scale production of nanoporous carbons is a well-established process since the first patents date from the beginning of the twentieth century. Conventional activation methodologies are divided between physical, using steam or CO 2 , and chemical, being KOH, ZnCl 2 , and H 3 PO 4 the most commonly reported oxidizing agents. Due to the panoply of operational parameters that can be changed or added in the production of activated carbons, there is still room for R&D. In this chapter, both conventional and innovative synthetic processes are reviewed to offer an up-to-date picture regarding raw materials, carbonization step, activation process, and other approaches. Conventional activation of gels and chars obtained by novel approaches (i.e. sol-gel method, hydrothermal carbonization (HTC), and acid-mediated carbonization) and more innovative strategies (i.e. variations of HTC process, carbonization of organic salts and ionothermal approaches) are addressed. Textural, surface chemistry and morphological properties of the derived porous carbons were reviewed and critically rationalized.

In this work, the progress in the design of nonsiliceous mesoporous materials (nonSiMPMs) over the last five years from the perspectives of the chemical composition, morphology, loading, and surface modification is summarized. Carbon, metal, and metal oxide are in focus, which are the most promising compositions. Then, representative applications of nonSiMPMs are demonstrated in energy conversion and storage, including recent technical advances in dye‐sensitized solar cells, perovskite solar cells, photocatalysts, electrocatalysts, fuel cells, storage batteries, supercapacitors, and hydrogen storage systems. Finally, the requirements and challenges of the design and application of nonSiMPMs are outlined.

“…Heteroatom‐doped porous carbon materials are important material of construction and function which are increasingly employed for versatile applications in gas separation, water purification and gas storage, catalysis and catalytic supports, electrochemistry and so on . The traditional approach of preparing heteroatom‐doped porous carbon materials always take nonrenewable fossil resources or expensive and complicated materials (e. g. MOFs, polymers, or ionic liquids) as raw materials, and the most frequently methods to fabricate heteroatom‐doped porous carbons with high surface area are post‐treatment with heteroatom sources and in‐situ doping by carbonization of heteroatom‐rich precursors . Both methods generally require tedious and multi‐step processes with the assistance of hard/soft templates or the activation with considerable amounts of chemical reagents, the processes are time‐consuming, energy‐dissipation, and cost‐wasting along with massive waste production.…”

Heteroatom‐doped porous carbon derived from biomass have recently received increasing attention due to their unique properties such as high electrical conductivity, large specific surface area, high porosity, and easy availability, which are appealing materials for versatile applications in catalysis, energy, separation and adsorption, and life sciences as well. On the basis of our previous work in this field, we summarized in this account our recent progress on design, synthesis of metal (e. g., Pd, Co) nanoparticles supported heteroatom‐doped hierarchical porous carbon material derived from bamboo shoots and their applications for important organic transformations, including chemoselective semihydrogenation of alkynes, hydrosilylation of alkynes, cascade synthesis of benzofurans from terminal alkynes and iodophenols, selective hydrogenation of functionalized nitroarenes to form anilines, imines, and formamides. Finally, the current state and future challenges in this field are discussed. We hope this account could shed light on the rational design of novel non‐noble metal based heterogeneous catalysts derived from biomass for efficient and sustainable organic transformations.
