Palladium has been the focus of recent research into Pt-alternative catalysts for the oxygen reduction reaction (ORR).In this manuscript,we developed a Pd catalyst supported on exfoliated montmorillonite (ex-MMT) nanoplatelets for the ORR.We unexpectedly found that a thin PdOx layer with a Pd-O-MMT junction is formed at the particle/support interface.The thin PdOx layer was experimentally observed.First-principle calculations further revealed that the junction is formed between the Pd atoms and the O atoms in the AlO6 octahedra of the ex-MMT.

物理冶金法提纯多晶硅技术具有产量大、成本低、不涉及化学过程及设备价格较低等优点。但与常规化学法提纯的光伏多晶硅材料相比,硼和金属杂质等含量还是有些高,所以使制作的物理多晶硅太阳电池的光电转换效率偏低,反向电流较大。不断降低物理冶金多晶硅电池的漏电,提高其短路电流和光电转换效率是重要的任务。本工作针对冶金多晶硅电池漏电大的问题,把常规晶体硅电池表面的双层氮化硅减反射膜设计成三层氮化硅薄膜,增大第一层
