Three-dimensional layered double hydroxide membranes: fabrication technique, growth mechanism, and enhanced photocatalytic activity

Novel three-dimensional ZnAl-LDH/AAO and NiAl-LDH/AAO membranes using porous anodic aluminum oxide (AAO) templates as a substrate and an Al3+ source were successfully fabricated via a simple precipitant-free in situ growth technique. These membranes with uniform layered double hydroxide (LDH) plates...

Summary:Novel three-dimensional ZnAl-LDH/AAO and NiAl-LDH/AAO membranes using porous anodic aluminum oxide (AAO) templates as a substrate and an Al3+ source were successfully fabricated via a simple precipitant-free in situ growth technique. These membranes with uniform layered double hydroxide (LDH) plates on the outer and inner surfaces exhibit enhanced activities in photocatalysis.
