摘要：

We have carried out EXAFS analyses on polymer-protected CuPd nanoparticles with sizes of about 1.4 nm. We found that the Cu-Pd heterobond was preferentially created in the CuPd nanoparticle and we called this type of structure a "heterobondphilic structure". DFT calculation indicated the electron transfer from Cu to Pd which stabilized the CuPd nanoparticle. The catalytic activities and their relation to the heterobondphilic structure were discussed.
