Sulfur doped biocarbon obtained from Sargassum spp. for the oxygen reduction reaction

Structural and compositional analysis of MOF-derived carbon nanomaterials for the oxygen reduction reaction

“…Notably, various 2D substrates, such as MXenes, transition metal dichalcogenides, and foam metals, have been extensively studied as MOF growth substrates. 34,72 Huang et al utilized foamed nickel as a carrier to grow Ni-Co-based MOF nanosheets. The 2D MDCNM formed after pyrolysis under an N 2 atmosphere successfully attained high electrical conductivity and porosity.…”

Boron and Fluorine Co‐Doped Graphene/Few‐Walled Carbon Nanotube Composite as Highly Active Electrocatalyst for Oxygen Reduction Reaction

“…[22,26] Mostly N, P, S and B doping have been investigated owing to their reasonable atomic size in order to enter the carbon network. [26][27][28][29][30][31][32] Fluorine-doped carbon materials have lately attracted much attention mostly because of the high electronegativity of this element. [33][34][35][36] High electronegativity is also one of the main reasons why fluorine has been widely used as co-dopant along with N, B and S. [37][38][39][40][41] Previous works have shown that introducing other atoms with different electronegativities than the host atomic network breaks the electroneutrality of the material and creates favorable adsorption sites for O 2 .…”

“…In fact, doped carbon materials are attractive due to their low cost, good tolerance to fuel impurities, long‐term stability and good electrocatalytic activity towards the ORR [22,26] . Mostly N, P, S and B doping have been investigated owing to their reasonable atomic size in order to enter the carbon network [26–32] . Fluorine‐doped carbon materials have lately attracted much attention mostly because of the high electronegativity of this element [33–36] .…”
