“…Surprisingly, the bands at 1384 and 1470 cm −1 are related to the CN stretching vibrations, confirming the carbon doped by nitrogen. They could promote the moving rates of electrons . Importantly, owing to the plentiful cyano groups, the FeNC variation stretching was found at 1000 cm −1 , which is beneficial for the ions transferring …”

Designing potential anodes for sodium-ion battery with both remarkable durability and high-rate capability has captured enormous attention so far. The engineering of size and morphology is deemed as an effective manner to boost the electrochemical properties. Owing to the anisotropic self-assembly of iron selenide, rod-like FeSe 2 coates with nitrogen-doped carbon is prepared through the thermal reaction of Prussian blue with selenium. Notably, the cyano groups are effectively transformed into N-doped carbon with FeNC bonds, which uniformly coats FeSe 2 , prompting Na + transportations. Interestingly, the particle size is tailored by heating rates, along with increased carbon content, leading to broadened energy levels for redox reaction. Bestowed by these advantages, the FeSe 2 /N-C as Na-storage anode delivers impressive electrochemical properties. Even at a rather high rate of 10.0 A g −1 , a considerable capacity of 308 mAh g −1 is yielded over 10 000 loops. Supported by the detailed analysis of kinetic features, reduced size of particles could bring about the enhanced contributions of pseudocapacitive and quickening rate of ions transferring. The phase evolutions are further investigated by in situ EIS and ex-situ technologies. The work is expected to provide a new strategy to prepare metal-selenide with controllable size and induce the faster kinetic of high-rate materials.

“…To avoid any expensive precursors NCDs are prepared from fruit peels or juices (lemon, grapes, lychees, avocado, kiwi etc. ), vegetables, milk, and willow bark, which have abundance of polyphenolic and phenolic compounds that exhibit antioxidant properties which further enrich their synthesis [ 31 , 32 ]. This green synthesis approach is highly sustainable, minimizes waste production, highly biocompatible, environmental friendly, easy handling and non-toxic.…”

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.
