Efficient photocatalytic NO oxidation over novel NiAl layered double hydroxide/Bi4Ti3O12 Z-scheme heterojunctions with boosted charge separation and O2 activation

The novel NiAl-LDH/Bi 4 Ti 3 O 12 Z-scheme heterojunction exhibits excellent NO oxidation performance with low toxic NO 2 generation. The enhanced activity can be attributed to the boosted charge separation and optimized oxygen activation capability.
