Abstract

The traditional concept that nickel layered double hydroxide (Ni LDH, also known as α-Ni(OH)₂) converts to NiO after annealing has been taken without doubt and utilized to fabricate NiO for years. This work reports that an anomalous self-reduction phenomenon can occur for Ni LDH synthesized from an ionic liquid system.
