Facile pyrolysis approach of folic acid-derived high graphite N-doped porous carbon materials for the oxygen reduction reaction

Abstract

Development of active and stable carbon nanomaterials as electrocatalysts for the oxygen reduction reaction (ORR) is still a significant challenge up to date. Herein, we report a one-step pyrolysis process...

Mesoporous carbon-based materials and their applications as non-precious metal electrocatalysts in the oxygen reduction reaction

“…These include conducting polymers such as polyaniline, as it has a high N/C ratio [91,94], and polypyrrole [95], and graphitic carbon nitride, g-C 3 N 4 as it releases large amounts of N-containing gases at high temperatures [27]. Other nitrogen sources include melamine [96], 2-pyridinecarboxaldehyde, pyrrole [19], folic acid [97], amino acids and poly amino acids as they are all rich in nitrogen [98]. There is also increasing interest in forming nitrogen-doped MC materials from biomass waste [99].…”

High-dispersion Co/N/C ultra-thin carbon nanosheets modified with trace Ce as efficient oxygen reduction reaction catalysts

“…Folic acid (FA) can be carbonized at low temperature, with large supply and no pollution. 26 It is composed of a pteridine ring, p -aminobenzoic acid, and l -glutamic acid. It has a very high content of N elements and a large number of –COOH, –NH 2 , and –OH functional groups, which can coordinate with metal ions.…”

Development of Nanocomposites based on Layered Double Hydroxides and graphene-like materials

“…Nanocomposites constituted by graphene-like materials and layered double hydroxides (LDH) present potentiality to be applied in sensing, catalysis, energy storage devices, environmental remediation and in nanomedicine (drug delivery system and theragnostic agent), for instance (Zhao et Hybrid materials constituted of LDH intercalated with anionic organic species are As shown in Figure 1b, FA is formed by pterin (PT), p-aminobenzoic acid (p-ABA) and Lglutamic acid (Glu) moieties (Figure 1b), making it a source of carbon and nitrogen as well as building blocks of aromatic rings for graphene-like materials, such as C-dots (Zhang et al, 2019) and graphitic carbon (Liu et al, 2021). Although the intercalation of folate anions into LDH has already been reported, to the best of our knowledge, the use of LDH-FA hybrid materials was not explored yet for such purposes.…”
