C-saturated Pd nanoparticles with an extended phase boundary to ZrO evolve from a Pd Zr precatalyst under CH dry reforming conditions. This highly active catalyst state fosters bifunctional action: CO is efficiently activated at oxidic phase boundary sites and Pd C provides fast supply of C-atoms toward the latter.
在CH干重整条件下，具有与ZrO扩展相界的C饱和钯纳米颗粒由Pd-Zr预催化剂演变而来。这种高活性催化剂状态促进了双功能作用：CO在氧化相界位点被有效活化，而Pd-C为后者提供快速的C原子供应。
