In this study, an attempt was made to modify the photocatalytic properties of an ion-exchangeable semiconductor material to enhance the efficiency of hydrogen production. Visible-light active NiFe2O4was loaded onto Nisingle bondZn/Cr layered double hydroxide (LDH) (Ni/Zn molar ratio = 75/25) with the Fe/Cr molar ratio of 0.005, 0.010, and 0.015 as cocatalyst through a simple solvothermal process and subsequently subjected to calcination at temperature of 500 °C. The results revealed that the presence of the loaded cocatalyst significantly facilitated the photocatalytic activity and the mixed oxide with Fe/Cr = 0.010 displayed the highest photocatalytic activity for visible light-induced H2generation. The optimal amount of hydrogen evolution reached to 269.44 μmolh−1under visible light (λ > 420 nm), which is far superior to that of the pristine Nisingle bondZn/Cr LDH-derived oxides material (130.85 μmolh−1), indicating the important catalytic role of NiFe2O4. The significant enhancement in photoactivity was attributed to the synergistic effect of nickel ferrite attached on the external surface of the calcined brucite-like sheets of the LDH. The cocatalyst NiFe2O4nanoparticles increase the donor or acceptor levels in comparison with the pristine Nisingle bondZn/Cr LDH-derived semiconductor oxide. Moreover, the existence of sheet-like LDH-derived carrier could inhibit the rapid recombination of photogenerated electrons and holes.
