“…The inherent structure and surface composition of HPC−X samples were studied by XRD and Raman spectroscopy. Figure c shows the result of XRD spectrum reveals two broader and weaker diffraction peaks around 25° and 44°, which is correspond to the (002) and (101) plane, respectively . The former peak was attributed to the reflection of the graphite lattice, and the latter peak is determined by the superposition of lattice reflections.…”

In this study, cost‐effective hierarchically porous carbon (HPC) derived from starch was successfully prepared through a simple mixing and subsequent one‐step carbonization method. Based on the three‐dimensional interconnected hierarchically porous structure, HPC exhibits a high specific surface area of 2259.54 m2 g−1 and a specific capacitance of 385.7 F g−1 at 1 A g−1 in a three‐electrode system. When the as‐prepared carbon was employed to fabricate an aqueous symmetrical supercapacitor, the device displayed a high specific capacitance of 81.3 F g−1 at 1 A g−1, and even at 20 A g−1 the specific capacitance remained 64 F g−1 (capacity retention rate of 78.72 % compares with that at 1 A g−1), demonstrating an outstanding rate performance. This supercapacitor maintained a capacity retention of 100 % after 60 000 cycles at a current density of 5 A g−1, indicating superior long‐term cycling stability. Furthermore, when the as‐prepared carbon was employed to fabricate a symmetrical supercapacitor in ionic liquid (1‐ethyl‐3‐methylimidazolium tetrafluoroborate, EMIMBF4) electrolyte, it ultimately achieved an ultrahigh energy density of 133.94 Wh kg−1 (power density of 1997.51 W kg−1) and a capacity retention rate of 83.3 % was maintained after 5000 cycles throughout a wide operating potential window of 0–4 V at 10 A g−1.

“…Moreover, N ‐PC‐900 shows a very high S BET (more than 2000 m 2 g −1 , while the weight ratio of ILs to salt is 1:5). N‐doped nanocarbons differ from g‐C 3 N 4 based materials in their electronic structures, transport behaviour, and optical properties, which also has a potential for outstanding photocatalytic properties . Regrettably, however, the N‐doped nanocarbon photocatalysts receive markedly less attention and further research into the design and preparation of these novel nanostructures would be beneficial.…”

Photocatalytic solar energy conversion and environmental remediation including water splitting, CO2 reduction, and pollutant degradation have attracted rapidly growing attention, owing to global fossil fuel depletion and increasing environmental issues. From the viewpoint of the broad availability, good environmental acceptability, high corrosion resistance, as well as the readily tailorable microstructure, electronic structure and surface chemical properties, carbonaceous materials have been demonstrated as promising and sustainable low‐cost metal‐free alternatives to metal‐based photocatalysts for solar fuel production and pollutant degradation. The non‐metallic heteroatoms doping approach has been considered as a powerful tool for modulating electronic structure, morphology, surface structure and surface chemistry, textural properties, optical properties, and electrochemical properties, as well as catalytic properties of carbonaceous photocatalysts. This Review represents a comprehensive overview of the latest advance in preparation and physicochemical properties of diverse non‐metallic heteroatoms‐doped carbonaceous materials, as well as their applications in heterogeneous photocatalysis towards solar energy conversion and environmental remediation. The physicochemical properties and photocatalytic performance of the carbonaceous photocatalysts are carefully compared, as well as a brief overview of fundamental principles for the promoting effect of heteroatoms‐doping is also presented. In addition, the future perspectives on the opportunities and challenges of heteroatoms doping for fabricating novel and excellent carbonaceous photocatalysts are outlined.

“…The main factors that enable choosing carbon materials as electrode materials are the following: a very well-developed surface area, appropriate pore geometry, pore size distribution (PSD), high conductivity, good wettability, and appropriate surface functional groups. The most critical seems to be a compromise between a high surface area (to ensure high capacity) and the presence of broad pores (to allow easy access to the electrolyte) [ 181 ].…”

Marine-derived as well as freshwater feedstock offers important benefits, such as abundance, morphological and structural variety, and the presence of multiple elements, including nitrogen and carbon. Therefore, these renewal resources may be useful for obtaining N- and C-containing materials that can be manufactured by various methods, such as pyrolysis and hydrothermal processes supported by means of chemical and physical activators. However, every synthesis concept relies on an efficient transfer of nitrogen and carbon from marine/freshwater feedstock to the final product. This paper reviews the advantages of marine feedstock over synthetic and natural but non-marine resources as precursors for the manufacturing of N-doped activated carbons. The manufacturing procedure influences some crucial properties of nitrogen-doped carbon materials, such as pore structure and the chemical composition of the surface. An extensive review is given on the relationship between carbon materials manufacturing from marine feedstock and the elemental content of nitrogen, together with a description of the chemical bonding of nitrogen atoms at the surface. N-doped carbons may serve as effective adsorbents for the removal of pollutants from the gas or liquid phase. Non-recognized areas of adsorption-based applications for nitrogen-doped carbons are presented, too. The paper proves that nitrogen-doped carbon materials belong to most of the prospective electrode materials for electrochemical energy conversion and storage technologies such as fuel cells, air–metal batteries, and supercapacitors, as well as for bioimaging. The reviewed material belongs to the widely understood field of marine biotechnology in relation to marine natural products.
