摘要：

Curvy cubes: Palladium concave nanocubes enclosed by high-index {730} facets were obtained in high purity by controlling the overgrowth of Pd cubic seeds (see scheme). The concave nanocubes showed a much higher catalytic activity than the conventional Pd nanocubes enclosed by {100} facets for both electro-oxidation of formic acid and Suzuki coupling reaction. © 2011 Wiley-VCH Verlag GmbH & Co.
