Winterberries-like 3D network of N-doped porous carbon anchoring on N-doped carbon nanotubes for highly efficient platinum-based catalyst in methanol electrooxidation

MnO–Co@Pt nanowires encapsulated in N-doped porous carbon derived from MOFs for efficient electrocatalytic methanol oxidation reaction

“…The presence of C-N bonds at 285.5 eV suggests effective doping of N atoms into porous carbon, resulting in the generation of more active sites and improved electrical conductivity of the catalyst. 44,45 The N 1s spectra of the MnO-Co@Pt NPC (Fig. 4d) were divided into ve peaks at 397.9 eV, 398.9 eV (metal-N x ), 399.7 eV (pyrrolic N), 400.9 eV (graphitic-N), and 403.3 eV (N-oxides).…”

Scalable production of bifunctional ordered PtFe alloy electrocatalysts for efficient methanol oxidation and hydrogen evolution

“…35,36 Therefore, high nitrogencontent carbon (HNC) was chosen as a support for ordered Ptalloy nanoparticles due to its rich mesopores and high specific surface area to suppress the growth and simultaneously improve the dispersion of alloy nanoparticles during the annealing. [37][38][39] Herein, we have designed a simple and delicate approach for scalable synthesis of porous HNC supported ordered PtFe alloy nanoparticles with NC shells labelled as PtFe@HNC. The unique PtFe compounds and porous HNC supports cooperatively contribute to the formation of sub-5 nm sized ordered PtFe alloy nanoparticles and their good dispersion upon annealing.…”

Engineering Flower-like Ni3S2 on Nanoporous CuAg Alloy Heterostructure for Efficient Methanol Oxidation Reaction

“…The rapid depletion of conventional fossil fuels, along with rising environmental pollution, has spurred an urgent demand for novel environment-friendly and efficient energy conversion devices. − Among various energy carriers to replace fossil fuels, methanol shows great potential because of its affordability, high energy density, and low carbon emission. − In particular, direct methanol fuel cells (DMFCs) have been recognized as prospective energy conversion devices, because of their high energy conversion efficiency, easy storability and transportability, environmental friendliness, and mild operating temperatures. − To date, the reactions on anode electrodes in DMFCs have been yet heavily dependent on Pt-based precious metal electrocatalysts . Despite the excellent activity of Pt-based catalysts, the scaled-up application of DMFCs has been largely hindered by their high price and extreme scarcity. , Moreover, it is worth noting that Pt-based catalysts are prone to be poisoned by intermediate products, leading to a significant deterioration in both electrocatalytic activity and stability.…”
