Synthesis and electrochemical characterization of stabilized nickel nanoparticles

Direct growth of 3D flower-like Pt nanostructures by a template-free electrochemical route as an efficient electrocatalyst for methanol oxidation reaction

“…As can be seen, the Pt nanoflowers with porous nature have been homogeneously distributed at the surface of electrode and appeared with nearly uniform size (300e500 nm). As described in literature [33,37], dynamic growing processes of the Pt NFs could be illustrated as follows: the quasi-spherical studded particles are initially made with some small pricks on the surface at the earlier steps which act as the nuclei for subsequently forming Pt NFs [38]. With increasing deposition time, the growth of pricks becomes much faster in the direction of perpendicular to a high-index plane [19].…”

Enhanced Catalytic Activity of Iron‐Promoted Nickel on γ‐Al2O3 Nanosheets for Carbon Dioxide Methanation

“…Different reports showed that nanoleaves, nano‐architectures, and nanoflowers can be obtained based on oriented attachment growth of crystals . Therefore, this method leads to a nanostructure that potentially allows enhancing the properties in Ni‐based catalysts to reach different morphologies from those obtained by other synthesis methods reported for this kind of catalyst, such as solvothermal reduction, thermal decomposition, and microwave‐assisted reduction …”

Facile synthesis of flower-like platinum nanostructures as an efficient electrocatalyst for methanol electro-oxidation

“…4c) grew and displayed a quasi-spherical morphology, and their average size was similar to that of Pt/GNF-30. As described in the literature [31,32], the dynamic growth of Pt nanoflower particles involves two steps: (i) the initial generation of quasi-spherical studded particles with small pricks on the surface that serve as the nuclei for forming Pt nanoflowers; and (ii) the accelerated growth of pricks in the direction perpendicular to a high-index plane as the reaction time is prolonged. The appearance distinguished from the nanoflowers to the nanoparticles can be attributed to the fact that partial Ni was removed from GNF and a rough surface was produced after etching (Fig.…”
