| 1 | A rapid synthesis of high surface area PdRu nanosponges:Composition-dependent electrocatalytic activity for formic acid oxidation显示文摘Here, Pd Ru nanoparticle networks(NPNs) with various compositions were synthesized through an inexpensive method in water as a green solvent, at different ratios of the H_2PdCl_4 and RuCl_3 precursors. This is a fast, room temperature and surfactant free strategy which is able to form high surface area metal nanosponges with a three-dimensional(3D) porous structure. The structure of as-prepared nanosponges was characterized using the techniques of field emission scanning electron microscopy(FESEM), energy dispersive spectroscopy(EDS) and cyclic voltammetry(CV). Then, the electrocatalytic activities of Pd Ru NPNs towards formic acid oxidation were examined by electrochemical measurements including CV,chronoamperometry, and electrochemical impedance spectroscopy(EIS). Based on studies, it was found that the current density of formic acid oxidation(FAO) is strongly dependent on the composition of Pd Ru NPNs. The best performance was realized for Pd_4Ru_1 NPNs compared to monometallic Pd counterpart and other bimetallic NPNs which might be ascribed to the role of Ru in the decrease of CO adsorption strength on the catalyst and consequently the priority of formic acid oxidation through the direct pathway. The Pd_4Ru_1 NPNs also showed the maximum current density and stability in chronoamperometric measurements. In addition, comparative studies were performed between as-prepared NPNs and CNTs-supported Pd nanoparticles(Pd NPs/CNTs). The present results demonstrated the unique structural advantages of NPNs compared to individual Pd NPs supported on the CNT which leads to the promising performance of NPNs as supportless catalysts for the oxidation of formic acid. | Ehteram Hasheminejad Reza Ojani Jahan Bakhsh Raoof | 2017 | Journal of Energy Chemistry2017，26，4： | 2 |
