Pt–Ni nanodendrites with high hydrogenation activity

Bimetallic highly branched Pt-Ni nanocrystals were obtained by a one-pot strategy. The dendritic alloyed structure of the as-prepared nanoparticles was fully characterized and their formation mechanism was investigated. Nitrobenzene hydrogenation reactions indicated that these obtained Pt-Ni nanodendrites exhibited enhanced catalytic activities compared with Pt-Ni nanoparticles.
