The Pd-Cu/C catalysts were shown to have the face centered cubic crystal structure. This could indicate that the addition of Cu shortened the Pd-Pd distances in the crystal lattice, and therefore –HO(subscript 2ads) and O-O could be better adsorbed on the surface of the catalyst. When NaBH4 was used as the reducing agent, and the atomic ratio of Pd to Cu was 3:1, the resulting catalysts had an average particle size of 3. 4nm and showed the best catalytic performance. The electrochemical active surface are a of Pd3Cu/C was 38.9m^2/gPd and the oxidation reduction reaction activity of the Pd3Cu/C catalyst was much higher than that of the Pd/C catalyst. The electrochemical activity of the Pd3Cu/C catalyst was comparable to that of a commercial Pt/C catalyst.

结果表明：催化剂中Pd与Cu的物质的量之比与预设值相近，Pd和Cu基本被全部还原；Pd-Cu/C催化剂为面心立方结构，元素铜的加入使催化剂的Pd-Pd间距缩小，从而HO(下标 2 ads)和OO键能更好地吸附在催化剂金属表面；当采用NaBH4为还原剂，Pd与Cu物质的量比为3：1时，催化剂(Pd3Cu/C)的平均粒径为3.4 nm，催化剂的催化性能最好，电化学活性表面积EAS达到38.9平方公尺/gPd，电化学性能较Pd/C催化剂有很大提高，接近Pt/C商用催化剂。

Crown ether was introduced to copolymerize with the monomer of styrene owing to which can associate with silver ions. The silver ions were in-situ reduced to silver nanoparticles by UV light. Then silver nanoparticles were led on the surface of polystyrene latex particles. The vertical precipitation was employed to get the spheres self-assembled into close packed colloidal crystal with a face centered cubic structure identified.
