Abstract
Abstract
This work is based on the preparation of Au–Pt NSs (Nano stars) @Au core, Au–Pt NSs@Au1Pt3 core, Au–Pt NSs@Au1Pt1 core, Au–Pt NSs@Au3Pt1 core and Au@Pt NCs (Nano cubes) by a seed-mediated synthesis route. The characterizations of the prepared bimetallic NSs and NCs were conducted with ultraviolet-visible spectroscopy, X-ray diffraction, transmission electron microscopy, and inductively coupled plasma optical emission spectroscopy. The catalytic activities of the prepared Au–Pt NPs for 2-nitrophenol (2NP), 3-nitrophenol (3NP), 4-nitrophenol (4NP), 2-nitroresorcinol (2NR), and 4-nitrocatchol (4NR) reduction have been investigated. The results evidently demonstrated that the superior catalytic activities of Au–Pt alloy nano-dendrites can be attributed to the metal–metal connection (synergy between Au and Pt) in the catalysts.
