NiPd co-doped nitrogen-coordinated graphene as a high-efficiency electrocatalyst for oxygen reduction reactions: a first-principles determination

“…S9(d), ESI †]. According to eqn (7) and ( 8), the calculated theoretical overpotentials of different paths are shown in Fig. 8(b).…”

“…Since isolated Pt atoms were first anchored on iron oxide to construct Pt 1 /FeO x for CO oxidation, 3 single-atom catalysts (SACs) have attracted extensive attention because of their maximized metal utilization efficiency and extremely high catalytic activity, [4][5][6] especially single metal-doped non-metal coordinated graphene SACs. 7 Moreover, N, O, and S are common coordinated elements in available studies. [8][9][10] However, single metal-doped nitrogen-coordinated graphene (M-N-G) SACs can not only maintain the planar structure of graphene but also effectively regulate the electronic structure of the M atom due to the higher electronegativity of the N atom and a similar atomic size to C, 11 exhibiting good structural stabilities and catalytic activities.…”

CoP nanoparticles embedded in three-dimensional porous network-like structured N, O co-doped carbon nanofibers as an effective bi-functional electrocatalyst for rechargeable zinc–air batteries

“…Among many modification methods, a commonly used strategy is to prepare some functional and modified carbon-based electrocatalysts, which are seen as potential alternatives to noble-metal electrocatalysts due to some advantages of carbon materials such as large specific surface area, excellent electronic conductivity and stability, easy preparation and modification and the synergism of activated carbon and its corresponding modified substances. 8–10…”

[8][9][10] In current research studies, some functional modified carbon materials are also widely used in oxygen electrocatalysis. Chemical doping is a direct and effective strategy for functionalizing current electrocatalysts.…”

Trace Mn decorating nitrogen-doped carbon electrocatalysts for self-powered bio-electro-fenton cells toward simulated wastewater treatment

“…Moreover, the integration of nonmetallic heteroatoms into transition metal-doped carbon materials provides the opportunity to modulate the electronic structure of active sites or introduce defect sites, thereby augmenting the catalytic activity of electrocatalysts. 19 Particularly, nitrogen (N) elements can function as highly effective catalytic active sites for a wide range of reactions due to their high electronegativity and adjustable electronic structure. 20,21 However, it is important to note that most traditional N-doped ORR electrocatalysts are synthesized using agents such as dicyandiamide or melamine, which tend to exhibit a preference for the 4e − reduction pathway of O 2 .…”
