▎ 摘　　要

NOVELTY - A three-dimensional graphene foam, porous carbon foam or porous metal foam as conductive substrate and metal salt precursor are crystallized and hydrothermal reacted at different temperature, to obtain vertically-aligned bimetallic hydrotalcite nanosheet. USE - Preparation of vertically-aligned bimetallic hydrotalcite nanosheet (claimed). ADVANTAGE - The method enables preparation of vertically-aligned bimetallic hydrotalcite nanosheet with high yield by simple method.
