Solid-state phase transformations in solution: templated conversion of nanoscale nickel phosphides

摘要

Conversion of Ni_12P_5 nanoparticles to Ni_2P is demonstrated to occur via a solid-state, rather than a solution dissolution, process. The templated transformation is employed to make monodisperse hollow or solid particles of the catah tieally active phase Ni_2P with surface areas of ~ 17 m~2 g~-1.
