“…In addition, the addition of CTAB significantly decreases the growth rates as well as inducing the anisotropic growth of PdPb NCs with high surface active areas. [44][45][46] Figure 4a and b showed that the products structures changed dramatically when substituted CTAB with CTAC. When CTAB was changed into TBAB, the morphology of the as-prepared samples changed from NCs to irregular shapes (Figure 4c, d).…”

The design of nanocatalysts by controlling pore size and particle characteristics is crucial to enhance the selectivity and activity of the catalysts. Thus, we have successfully demonstrated the synthesis of binary PdPb alloy nanocubes (PdPb NCs) by controlling pore size and particle characteristics. In addition, the as-obtained binary PdPb NCs exhibited superior electrocatalytic activity of 4.06 A mg and 16.8 mA cm toward ethylene glycol oxidation reaction and 2.22 A mg and 9.2 mA cm toward glycerol oxidation reaction when compared to the commercial Pd/C. These astonishing characteristics are attributed to the attractive nanocube structures as well as the large number of exposed active areas. Furthermore, the bifunctional effects originated from Pd and Pb interactions help to display high endurance with less activity decay after 500 cycles, showing a great potential in fuel cell applications.

“…The surfactant not only hindered aggregation of nanowires, but also induced anisotropic growth of Ag nanowires. Various types of surfactants are also frequently used to assist and control the anisotropic growth of the atomic Ag nanoparticles to Ag nanowires that include hexadecyl-trimethylammonium bromide (CTAB) [51][52][53], sodium dodecyl sulfonate [54][55][56], vitamin B 2 [57][58][59], polyvinyl acetate (PVA) [60,61], dextran [62] and polymethyl vinyl ether [63]. In most chemical approaches, the employed charged precursor contains ions of the desired metal [64].…”

The recent interest to nanotechnology aims not only at device miniaturisation, but also at understanding the effects of quantised structure in materials of reduced dimensions, which exhibit different properties from their bulk counterparts. In particular, quantised metal nanowires made of silver, gold or copper have attracted much attention owing to their unique intrinsic and extrinsic length-dependent mechanical properties. Here we review the current state of art and developments in these nanowires from synthesis to mechanical properties, which make them leading contenders for next-generation nanoelectromechanical systems. We also present theories of interatomic interaction in metallic nanowires, as well as challenges in their synthesis and simulation.
