Abstract

In this study, the NiFe-LDH doped with different Pt group metals (Pt, Ru, Ir, Rh) was prepared as a cocatalyst for photocatalytic H₂ production over g-C₃N₄. It is found that the doped NiFe-LDH loaded g-C₃N₄ generally displays higher photocatalytic activity than the raw NiFe-LDH modified one, where the NiFeRu-LDH loaded g-C₃N₄ shows the optimal H₂ evolution rate of 77.4 μmol h⁻¹, about 5.5 times that of the NiFe-LDH system.
