Oxygen reduction reaction activity and surface properties of nanostructured nitrogen-containing carbon

Nitric acid activation of graphite granules to increase the performance of the non-catalyzed oxygen reduction reaction (ORR) for MFC applications

“…1B). Data reported in the literature showed that the increase of the catalytic performance of graphite material can be related to the increase of real surface area or due to the presence of superficial functional groups such as nitrogen groups [10] or oxygenated groups [8]. To determine how the acidic treatment affected the material surface, the granules structure, the porosity and the superficial groups composition were characterized from BET and XPS analysis.…”

Oxygen reduction reactions on pure and nitrogen-doped graphene: a first-principles modeling

“…[2][3][4][5][6][7][8][9]11 Meanwhile, nitrogen doped carbon nanosystems were intensively studied in the last couple of years as possible alternative to metal-based catalysts. [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] Light weight, low cost and high efficiency makes these materials attractive for the further practical applications.…”

Nitrogen-doped carbon xerogel as high active oxygen reduction catalyst for direct methanol alkaline fuel cell

“…The pyridine-N assignment have two edge carbon atoms bond to it, with a lone pair of electrons, often observed on the edge of graphite plane. Although this catalyst is with low graphitic degree, they present some defects, which can also cause the formation of pyridine-N [47]. Besides, graphite-N considered to be more stable than pyridine-N in acid media, may be also contribute to the high ORR [48].…”
