Abstract

It is still a challenge to fabricate metal nanoclusters (NCs) on a large scale. Here, we report a novel method to fabricate Pt/Cu NCs with a size of 1.6 ± 0.4 nm in a high yield of 1.2 g/h by using a continuous reaction in a static mixer. Cu ions accelerate the reduction of Pt significantly. The reduction time is significantly reduced from 30 min to 5 s stimulated by Cu ions. It is possible to continuously fabricate Pt/Cu NCs at a high flow rate due to fast reaction, and easy to obtain 1 L Pt/Cu NCs in 3 min' reaction.

快速、连续和可扩展的Pt/Cu纳米簇的合成

金属纳米团簇的大规模制备仍然是一个挑战。本文报道了一种在静态混合器中连续反应制备尺寸为1.6±0.4 nm的Pt/Cu纳米碳化物的新方法，收率高达1.2 g/h。Cu离子对Pt的还原有明显的促进作用。在Cu离子的刺激下，还原时间由30 min显著缩短至5 s。由于反应速度快，可以在高流速下连续制备Pt/Cu纳米材料，并且在3 min的反应中容易得到1 L的Pt/Cu纳米材料。

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
