“…In addition, pH dependences of contaminant reduction can provide some information on reaction pathways. In carbon-sulfide systems, reduction rates of nitrobenzene and acid yellow 36 decreased gradually with the increasing pH (Yu et al, 2011;Lu et al, 2014;Liu et al, 2017) suggesting the involvement of acid-enhanced proton delivery. For TCE and nitroglycerin, however, the pH dependences are opposite because alkaline condition favors the nucleophilic attack and enhances reducing capability of sulfide (Xu et al, 2010;Yang et al, 2020).…”

“…However, it is not able to conclude a consistent finding of contaminant dependence from currently available studies, for the reason that contrary results were reported even for the same contaminant, for example, nitroaromatic compounds mentioned before. Third, many other properties other than quinone moieties and graphitic regions were affecting the activity of carbon materials, including N elements (Ding et al, 2018;Liu et al, 2017), and affinities to different substrates. The extent of their influences may be small, but they can function with other properties synergistically to result in the diversity of catalytic performance.…”

Since the observation that carbon materials can facilitate electron transfer between reactants, there is growing literature on the abiotic reductive removal of organic contaminants catalyzed by them. Most of the interest in these processes arises from the participation of carbon materials in the natural transformation of contaminants and the possibility of developing new strategies for environmental treatment and remediation. The combinations of various carbon materials and reductants have been investigated for the reduction of nitro-organic compounds, halogenated organics, and azo dyes. The reduction

“…The field of C-MFCs has been expanding rapidly to cover various catalytic reactions beyond the ORR, OER, HER, and CO 2 RR. Examples include reduction of various organic chemicals, such as, 4-nitrophenol to 4-aminophenol (S-doped graphene), [174] nitroarene (N,P codoped multilayer graphene and B,N codoped graphene-like carbon), [175,176] and nitrobenzene (Ndoped nanoporous carbon), [177] to name a few. C-MFCs have also been used for many oxidation reactions, such as highly efficient CO oxidation (B,N codoped graphene), [178] oxidation of aqueous organic contaminants (S-doped porous carbon derived from thiophene), [179] aromatic alkanes (P,S codoped carbon nanosheets, N,P,S tridoped carbon shell), [180,181] aerobic oxidative coupling of amines (P-doped nanomesh graphene), [182] various hydrocarbon oxidation (graphene/g-C 3 N 4 composite), [183] and different organic chemical oxidation (surface modified nanodiamond, N,S codoped CNTs).…”

Precious noble metals (such as, Pt, Ir) and non-precious transition metals (e.g., Fe, Co), including their compounds (e.g., oxides, nitrides), have been widely investigated as efficient catalysts for energy generation, energy conversion, energy storage, important chemical productions, and many industrial processes. However, they often suffer from high cost, low selectivity, poor durability, and susceptibility to gas poisoning with adverse environmental issues. As a low-cost alternative, the first carbon-based metal-free catalyst (i.e., C-MFC based on N-doped carbon nanotubes) was discovered in 2009. Since then, various C-MFCs have been demonstrated to show similar or even better catalytic performance than their metal-based counterparts, attractive for energy conversion and storage (e.g., fuel cells, metalair batteries, water splitting), environmental remediation, and chemical production.

“…Moreover, nitrogen-doping can increase the interaction between the PdAu and NCB, thus enhancing the catalytic durability. [68][69][70] (2) In the case of the Ullmann coupling reaction, Pd appears to be more catalytically active than Au. The synergistic effect creates highly active sites, which is benecial to the oxidation addition of aryl halides.…”
