Well-ordered NiFe-MOF-74 is in situ grown on Ni foam by the induction of Fe 2+ and directly used as an OER electrocatalyst. Benefited from the intrinsic open porous structure of MOF-74, the in situ formed MOF arrays and the synergistic effect of Ni and Fe, outstanding water oxidation activity is obtained in alkaline electrolytes with an overpotential of 223 mV at 10 mA cm −2.

The surface topography of the composite coating is compact and homogeneous MOF-5 (sometimes called IRMOF-1) is a metal organic framework (MOF) formed from Zn 4 O with 1,4-benzodicarboxylic acid between the nodes. The spheres represent the pore size that can be … The formation of Mg-MOF-74 was confirmed by the presence of the characteristic peaks at 6.7°, 11.7° and 18° of MOF-74 in each XRD pattern,. In addition, the broad peaks observed in XRD pattern for the synthesis with DMF only (F1) suggests that nano-crystals are produced. In this work, Mn-MOF-74 with hollow spherical structure and Co-MOF-74 with petal-like shape have been prepared successfully via the hydrothermal method. The catalysts were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), thermogravimetry–mass spectrum analysis (TG-MS), N2 adsorption/desorption, scanning electron microscopy (SEM), and X-ray Consequently, unequivocal identification as the crystalline MOF-74 phase was deduced by combining other characterization techniques rather than powder X-ray diffraction.
