Enhancement of the photocatalytic activity of the NiO-porous NiO homojunction derived from the in situ templated metal–organic framework

The NiO@porous NiO homojunction derived from Ni(OH) 2 @Ni-MOF exhibited an excellent photocatalytic hydrogen production of 48.67 μmol h −1 g −1 , corresponding to 6.7 and 3.4 times in comparison with those of NiO and porous NiO, respectively.
