摘要：

Au-Pt heteroaggregate nanostructures were prepared by sequential reduction methods. The structures have ∼11 nm Au cores with Pt tendrils" attached to the Au surface. The heteroaggregates are active H2 oxidation catalysts and show high activity at 90 °C in the presence of 1000 ppm CO. The surprising CO-tolerant behavior arises from the composition and unusual architecture of the particles. Copyright © 2006 American Chemical Society."
