Pt纳米颗粒可以通过Pt溅射法在不含稳定剂的三甲基-正丙基铵双（（三氟甲基）磺酰基）酰胺（Me 3 PrNTf 2N）室温离子液体（RTIL）上制备。通过Pt溅射法获得的Pt纳米颗粒显示出约100 nm的平均粒径。2.3- 2.4nm，与溅射时间无关。由溅射铂的RTIL和玻碳板组成的铂嵌入玻碳电极（Pt-GCE）对氧还原反应具有良好的催化活性。Me 3 PrNTf 2N修饰的Pt-GCE的催化能力增强。另外。一氧化碳从未被吸收到RTIL改性的Pt-GCE上。(C)2009 Elsevier B. V.保留所有权利。
Pt nanoparticles can be produced by a Pt sputtering method onto trimethyl-n-propylammonium bis((trifluoromethyl)sulfonyl)amide (Me3PrNTf2N) room-temperature ionic liquid (RTIL) without stabilizing agents. Pt nanoparticles obtained by the Pt sputtering method showed mean particle size of ca. 2.3-2.4 nm independently of sputtering time. A Pt-embedded glassy carbon electrode (Pt-GCE) consisting of the Pt-sputtered RTIL and a glassy carbon plate showed a favorable catalytic activity to oxygen reduction reaction. The catalytic ability was enhanced by Me3PrNTf2N modification of the Pt-GCE. In addition. carbon monoxide never absorbed onto the RTIL-modified Pt-GCE. (C) 2009 Elsevier B.V. All rights reserved.
