Herein we report a novel method for the modification of metal NPs, denoted as electrochemical milling and faceting (ECMF), by which large Pd NPs (35 nm) of low-index facets supported on TiO2 can be milled into many small NPs (7 nm) with some HIFs or a high density of step atoms.

Abstract
Herein we report a novel method for the modification of metal NPs, denoted as electrochemical milling and faceting (ECMF), by which large Pd NPs (35 nm) of low-index facets supported on TiO2 can be milled into many small NPs (7 nm) with some HIFs or a high density of step atoms.
