铂纳米团簇的合成具有比表面积大、材料成本低等优点，是一类非常有意义的纳米材料。本文提出了一种不需要任何有机溶剂、模板剂或离子置换的一步法快速高效的水相反应，该反应通过微波辅助热处理含有K2 PtCl 4和2-[4-（2-羟乙基）-1-哌嗪基]乙磺酸（HEPES）的水溶液，在12 s内完成。所制备的铂纳米团簇是多孔互连的纳米结构，并具有非常高的表面积（41 m2 g（-1））。高表面积与由产物的孔组成的纳米结构的组合对于催化应用是有利的。
Synthesis of platinum nanoclusters (PNCs), with its advantages of high surface area and reduced materials costs, represents a greatly interesting class of nanomaterials. In this paper, a one-step, rapid and efficient aqueous-phase reaction to straightforwardly produce PNCs in high yield is proposed without the need for any organic solvent, template or ion replacement, which is carried out simply by microwave-assisted heat-treatment of an aqueous solution containing K2PtCl4 and 2-[4-(2-hydroxyethyl)-1-piperazinyl]ethanesulfonicacid (HEPES) within 12 s. As-prepared platinum nanoclusters are porous interconnected nanostructures and possess very high surface area (41 m2 g(-1)). The combination of high surface area with the nanoarchitectures consisting of pores of the product is advantageous for catalytic applications.
