The formation mechanism and photocatalytic activity of hierarchical NiAl–LDH films on an Al substrate prepared under acidic conditions†
Abstract
NiAl–LDH films with hierarchical morphology have been fabricated by immersion of an Al substrate in Ni2+-containing solutions under strong acidic conditions, and the growth processes of the films are discussed in this communication. The as-prepared LDH films exhibit high activity in the photocatalytic degradation of organic contaminants.
