Abstract Crystal phase regulations may endow materials with enhanced or new functionalities. However, syntheses of noble metal-based allomorphic nanomaterials are extremely difficult, and only a few successful examples have been found. Herein, we report the discovery hexagonal close-packed Pt–Ni alloy, despite fact that alloys typically crystallized in face-centred cubic structures. The alloy nano-multipods synthesized via facile one-pot solvothermal route, where branches take shape...

Controlled syntheses of multicomponent metal nanocrystals (NCs) and high-index surfaces have attracted increasing attention due to the specific physical chemical properties such NCs. Taking advantage copper underpotential deposition as a bridge, hexoctahedral Au-Pd alloy NCs with {hkl} facets exposed were successfully synthesized, while phase separation occurred in absence Cu(2+) ions. The as-prepared exhibited very excellent performance terms both formic acid electro-oxidation methanol...

Ultrathin crystalline nanosheets give an extremely high surface area of a specific crystal facet with unique physical and chemical properties compared normal three-dimensionally polyhedral nanocrystals (NCs). However, the ultrathin metal tend to curl themselves or assemble each other sheet by sheet, which may reduce effective accordingly catalytic activity great extent. Here we report facile wet-chemical route that allows fabrication novel excavated rhombic dodecahedral (ERD) PtCu3 alloy NCs...

Heterogeneous supported metal nanoparticles (NPs) are extensively applied in a variety of chemical and energy conversion processes. Traditionally, these catalysts prepared by deposition methods. However, they usually show wide ranging size distributions easily subject to poisoning coarsening or agglomeration during the reactions. Alternatively, time cost-effective situ exsolution strategy has successfully addressed above drawbacks is able produce finer more evenly distributed NPs even at...
