Ultrathin Pt-Based Alloy Nanowire Networks: Synthesized by CTAB Assistant Two-Phase Water-Chloroform Micelles

Ultrathin Pt-based PtM (M = Pd, Ru, An, Fe) alloy nanowire networks could be facilely synthesized using a soft template formed by cetyltrimethylammonium bromide in a two-phase water-chloroform system. The as-synthesized Pt-based alloyed nanowires show the fee crystal phase. They have an average diameter of similar to 2.3 nm and form porous nanonetworks, which can be potentially used for a number of catalytic applications. It was found that PtRu alloy nanonetworks showed more efficient catalytic activity for the hydrogenation of azo bonds in methyl orange than that of PtPd, PtAu, and pure Pt.
