Abstract

We report a facile method for the synthesis of Au@Pd nanostructures with controlled sizes and morphologies from flower-like to cuboctahedral shape by seed-mediated growth using Au nanospheres as seeds and cetylpyridinium chloride (CPC) as a surfactant. The use of CPC as a surfactant and its molar ratio with respect to Na2PdCl4 were critical factors to generate the Au@Pd nanostructures with flower-like morphology. In addition, the morphology of Au@Pd nanostructures could be easily controlled by changing the concentration of CPC in the reaction solution, where controlled reduction kinetics according to the concentration of CPC brought variety to the morphology of the Pd shell and eventually the Au@Pd nanostructures. The size of Au@Pd nanostructures could be also readily tuned in a controllable fashion by varying the concentration of Na2PdCl4. We also investigated the morphology-dependent electrocatalytic activities of Au@Pd nanostructures toward ethanol electrooxidation as a probe reaction. Thanks to their larger electroactive surface area and higher density of electroactive sites, the flower-like Au@Pd nanostructures exhibited 2.2 times enhanced electrocatalytic activity per Pd unit mass than cuboctahedral Au@Pd nanostructures.

CrystEngComm is the forum for the design and understanding of crystalline materials. We welcome studies on the investigation of molecular behaviour within crystals, control of nucleation and crystal growth, engineering of crystal structures, and construction of crystalline materials with tuneable properties and functions. We publish hypothesis-driven research into… how crystal design affects thermodynamics, phase transitional behaviours, polymorphism, morphology control, solid state reactivity (crystal-crystal solution-crystal, and gas-crystal reactions), optoelectronics, ferroelectric materials, non-linear optics, molecular and bulk magnetism, conductivity and quantum computing, catalysis, absorption and desorption, and mechanical properties. Using Techniques and methods including… Single crystal and powder X-ray, electron, and neutron diffraction, solid-state spectroscopy, spectrometry, and microscopy, modelling and data mining, and empirical, semi-empirical and ab-initio theoretical evaluations. On crystalline and solid-state materials. We particularly welcome work on MOFs, coordination polymers, nanocrystals, host-guest and multi-component molecular materials. We also accept work on peptides and liquid crystals. All papers should involve the use or development of a design or optimisation strategy. Routine structural reports or crystal morphology descriptions, even when combined with an analysis of properties or potential applications, are generally considered to be outside the scope of the journal and are unlikely to be accepted.
