“…Pd parti cles prepared by ethanol reduction, showed particles with a square outline from which three dimensional shapes determined were found to be cubic. Similar morphology was observed for Pt and Au nanoparticles prepared by H2 gas and hydroxylamine hydrochloride as the reducing agents respectively 41), 42) . In contrast to this, the radiolytic reduction of PdCl2 gave colloidal Pd particles of spherical and oval shapes, 1-5 nm diameter.…”

“…However, they also obtained a mixture of tetrahedral, polyhedra and irregular-prismatic particles. Milligan and Morris also observed cubical gold nanoparticles for hydroxylamine hydrochloride as the reducing agent [33]. In contrast to this, the radiolytic reduction of PdCl 2 gave colloidal Pd particles of spherical and oval shapes, 1-5 nm diameter.…”

“…Haruta prepared hemispherical gold nanoparticles supported on metal oxides for CO oxidation [16]. Controlling the shapes of Au particles as plate like trigons has been explained on the basis of Kossel-Stramki theory of face selective growth of crystals [17][18][19]. Formation of colloidal Cu particles having plate like hexagonal morphology has also been studied [20].…”

“…The synthesis of gold nanostructures with well-controlled morphology is important for uncovering their morphology-dependent properties and for achieving their practical applications. To date, some gold nanostructures, such as nanowires, [2] nanorods, [3][4][5][6] nanodisks, [6][7][8][9][10][11] nanorings, [12][13][14] nanocubes, [8,11,15,16] nanoboxes, [17,18] and branched nanocrystals, [8,19,20] have been routinely synthesized using the solution-phase approach. Recently, two-dimensional (2D) gold nano-objects with large surface areas that could be exposed to a gaseous environment have received considerable attention, mainly owing to their potential applications in efficient surface-enhanced Raman scattering substrates, [21,22] as gas sensors, [23][24][25] and for inducing hyperthermia in tumors.…”
