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. These small crystals are unstable as isolated ones, so they form steady and robust aggregates, whose mechanical properties strongly depend on the crystal size. The crystallinity of the MM-MOF-74 series was conﬁrmed by PXRDanalysis(Figure1).AllPXRDpatternsoftheMM-MOF-74 series coincide with the calculated PXRD pattern of the parent MOF-74 structure, indicating that the topology is retained and thus all members are isostructural.

IRMOF-74 analogues are among the most widely studied metal-organic frameworks (MOFs) for adsorption applications because of their one-dimensional channels and high metal density. Most studies

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.

N 2 adsorption–desorption measurements were performed to measure the surface area of Mg-MOF-74 films for different synthesis times of 4, 6, 12, and 24 hours, as shown in Fig. 6 a. Investigations of the structural transformation of Ni species derived from Ni‐MOF‐74 during heat treatment were conducted. The transformation was monitored in detail by a combination of XRD, in situ XAFS, and XPS measurements. The powder X-ray diffraction patterns of MM-MOF-74 were identical with those of single-metal MOF-74, and no amorphous phases were found by scanning electron microscopy. The successful preparation of guest-free MM-MOF-74 samples was confirmed by N 2 adsorption measurements.
