Shape-controlled catalysis: High-quality Pt-Cu nanocubes with an average size of about 8 nm (see picture, scale bar = 20 nm) were synthesized from a high-temperature organic solution system in the presence of various capping ligands. These cubic Pt-Cu nanocrystals terminated with {100} facets demonstrated a superior catalytic activity towards methanol oxidation compared to similar sized Pt-Cu and Pt nanospheres.
在各种封端配体存在的情况下,从高温有机溶液体系中合成了平均尺寸约为8nm的高质量Pt-Cu纳米立方体(见图,比例尺 = 20nm)。与类似尺寸的Pt-Cu和Pt纳米球相比,这些以{100}面为终端的立方Pt-Cu纳米晶体对甲醇氧化表现出优异的催化活性。
