控制合成具有高度支化形貌的贵金属纳米结构以获得特定的物理和化学性质已经引起了人们的广泛关注。本文报道了在果糖存在下，通过简单的一锅水热反应合成具有可控结构（多支化）的3D Pt纳米枝晶。在较高的反应温度下，果糖不仅作为还原剂，而且形成水热碳，作为封端剂吸附在金属纳米晶表面，诱导Pt纳米枝晶的各向异性生长。所制备的Pt纳米枝晶是高度多孔的，并且具有自支撑的纳米结构，具有高的表面积和许多反应物分子的吸收位点。Pt纳米枝晶对甲醇氧化反应具有比商用Pt/C更高的电催化活性和稳定性。
Controlling the synthesis of noble metal nanostructures with highly branched morphology to obtain specific physical and chemical properties has attracted much attention. This paper reports the synthesis of 3D Pt nanodendrites with controlled architectures (multibranched) by a simple one-pot hydrothermal reaction in the presence of fructose. At high reaction temperature, fructose not only acts as a reducing agent, but also forms a hydrothermal carbon, which, as a capping agent, is absorbed on the surface of metal nanocrystals and induces the anisotropic growth of Pt nanodendrites. The prepared Pt nanodendrites are highly porous, and have self-supported nanoarchitectures with a high surface area and a number of absorption sites for reactant molecules. The Pt nanodendrites exhibit a higher electrocatalytic activity and stability than commercial Pt/C for methanol oxidation reaction.
