Abstract
This study reports a facile boron-assisted strategy to prepare NiFe LDHs with rich grain boundaries. The formation of these grain boundaries originates from the imperfect oriented attachment between primary LDH particles transformed from amorphous borides/borates. The obtained grain-boundary-rich NiFe LDHs exhibit excellent oxygen evolution reaction activity.
