ABSTRACT
Neodymium-doped Ir/IrO2 hollow structure significantly reduces the geometric loading of Ir in anodic catalyst layer of PEMWE without compromising catalytic layer performance. Nd doping induces critical interfacial Nd-O-Ir configurations that stabilize lattice oxygen, while intensified electron effect among mixed valent Ir that inhibits the overoxidation of Ir active sites, synergistically ensuring enhanced catalytic durability. -

ABSTRACT
The ESI-MS of an open cubane cluster Zn4L4 exhibits both disassembly and reassembly fragments, which guide and lead to the successful synthesis of three new crystalline clusters Zn1, Zn4L6 and Zn6L6 corresponding to those observed in the MS. The series of ESI-MS for the clusters and crystal/solution/gas structural information relevance reveal assemble mechanism and the complex of chemical reactions. -
