Tandem MoP nanocrystals with rich grain boundaries for efficient electrocatalytic hydrogen evolution

Abstract

Constructing surface disorder including grain boundaries, stacking faults, and dislocation arrays in nanomaterials is an important strategy to enhance the catalytic activity of nanocatalysts. Here we report the facile synthesis of crystallographically interconnected MoP nanocrystals with abundant grain boundaries. They exhibit outstanding electrocatalytic activities for hydrogen evolution.
