“…This is consistent with the previous results for the plasmon-mediated conversion of Ag spheres into Ag nanoprisms, where a slow reaction rate, limited by the oxidative dissolution of the small Ag spheres, results in the growth of highly anisotropic {111}-faceted nanoprisms. [120,189] Interestingly, a control experiment in the absence of BSPP produced an additional particle morphology: {111}-faceted bitetrahedra. Without BSPP to coordinate to Ag + , reactions at pH 11 or 10 lead to a AgOH/Ag 2 O precipitate due to the low solubility of AgOH, and reactions at pH 6 or 7 generate primarily spherical nanoparticles due to a slow reduction rate at low pH and poor control over the Ag + concentration caused by the absence of BSPP.…”

“…Also, various shape-controlled Ag nanostructures including quasispheres [43], decahedrons [44], cubes [45], prisms [46], rods [47], wires [48], tubes [49], branches [50], sheets [51], plates [52] and belts [53] have been reported. However, to the best of our knowledge, there is no report concerned with AgNPs synthesis based on solid state reactions at ambient temperature so far.…”

“…Wie auch bei den Nanoprismen [139] [136] Diesen Studien zufolge ist die Geschwindigkeit der Ag + -Reduktion der eigentliche Hauptfaktor, der über das Wachstum von entweder Bipyramiden oder Prismen entscheidet (Abbildung 17). [136] Bei einem [BSPP]/[Ag + ]-Verhältnis von etwa 1 und einem pH-Wert von 10 oder 11 läuft die Ag + -Reduktion rasch ab, denn die Konzentration an verfügbarem Ag + ist hoch und das Citrat hat durch den hohen [120,189] Interessant ist dazu ein Kontrollexperiment ohne BSPP, das in einer neuen Partikelmorphologie mündete, Bitetraeder mit {111}-Kristallflächen. Ohne Ag + -koordinierendes BSPP in der Lçsung bildet sich während der Reaktion infolge der geringen Lçslichkeit von AgOH bei pH 11 oder 10 ein Niederschlag aus AgOH/Ag 2 O. Bei pH 6 oder 7 bilden sich dagegen hauptsächlich sphärische Nanopartikel, denn bei niedrigem pH-Wert ist die Reduktion verlangsamt und die Ag + -Konzentration ohne BSPP schwer kontrollierbar.…”
