| We report that ternary nickel-alumina-iron Layered Double Hydroxide (NiAlFe-LDH) is a highly active and stable oxygen evolution catalyst at neutral solutions. The LDHs were prepared using the co-precipitation method and were characterized by a field-emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD). According to powder X-ray diffraction and field emission scanning electron microscopy, NiAlFe-LDH exhibit a nanosized plate-like morphology with a basal space (d003) of 7.64 °A. Then amount of Al3+ at NiAlFe-LDH optimizes and the electrocatalytic activities of ternary-component were studied toward water oxidation in neutral solutions. The result compared with binary NiFe-LDH and NiAl-LDH. The obtained results show that the electrocatalytic activity of the ternary-component NiAlFe-LDH is much better than that of the binary-component NiFe-LDH and NiAl-LDH. The high electrocatalytic activity of ternary-component LDH may be attributed to the co-existence of Al and Fe active sites. | ||
