Ultralong Pt-on-Pd bimetallic nanowires with nanoporous surface: nanodendritic structure for enhanced electrocatalytic activity.
We for the first time report a facile, wet-chemical strategy for the high-yield (approximately 100%) synthesis of ultralong Pt-on-Pd bimetallic nanowires (NWs) with the cores being Pd NWs and the shells being made of dendritic Pt, which exhibit high surface area and enhanced electrocatalytic activity towards methanol oxidation reaction.
متن کاملFacile synthesis of ultrathin single-crystalline palladium nanowires with enhanced electrocatalytic activities.
Ultrathin single-crystalline palladium nanowires (PdNWs) were rapidly prepared using a facile one-step soft-template-directed method. The utilization of dioctadecyldimethylammonium chloride and an appropriate crystallization temperature determined the construction of PdNWs together. The obtained PdNWs exhibited good electrocatalytic performance toward formic acid oxidation.
متن کاملFabrication of cubic PtCu nanocages and their enhanced electrocatalytic activity towards hydrogen peroxide
Cubic PtCu nanocages (NCs) were successfully synthesized through a redox reaction using cuprous oxide (Cu2O) as a sacrificial template and reducing agent. The porous PtCu NCs were composed of amounts of PtCu nanograins with an average particle size of 2.9 nm. The electrocatalytic performance of the PtCu NC electrode towards H2O2 was studied by cyclic voltammetry (CV) and chronoamperometry. The ...
متن کاملOne-step synthesis of porous bimetallic PtCu nanocrystals with high electrocatalytic activity for methanol oxidation reaction.
The design of porous bimetallic nanocrystals (NCs) is very important for electrochemical energy conversion. Herein, we report an aqueous solution method for one-step fabrication of porous PtCu NCs assembled by spatially interconnected arms in high yield by a simple ultrasonic treatment of the reaction mixture at room temperature. The proposed method, without the need for multi-step synthesis, h...
متن کاملFacile and green synthesis of CuO nanoparticles and electrocatalytic activity of CuO nanoparticles/conductive polymer composite film
In this work, CuO nanoparticles (CuO NPs) was prepared by a simple and green method using Rosmarinus officinalis extract containing phenolic constituents as both the chelating and the stabilizing agents. CuO nanoparticles/polyorthoaminophenol composite (CuO NPs/POAP) as electro-active electrodes for electrocatalytic oxidation of methanol with good uniformity are prepared by electropolymerizatio...
