Structure. MOFs are composed of two major components: a metal ion or cluster of metal ions and an organic molecule called a linker. For this reason, the materials are often referred to as hybrid organic–inorganic materials; however, this terminology has recently been explicitly discouraged. A magnesium-based metal organic framework (MOF), also known as Mg-MOF-74, was successfully synthesized, characterized, and evaluated for adsorption equilibria and kinetics of CO 2 and CH 4. The Mg-MOF-74 crystals were characterized with scanning electron microscopy for crystal structure, powder X-ray diffraction for phase structure, and C0 C 0.0669848147496 0.228584349477 0.436908259086 1.727558 Uiso 1.00 C1 C 0.114935336832 0.196447741598 0.293040691884 -0.987069 Uiso 1.00 C2 C 0.110278083607 0.215529741387 0.096925016056 0.425146 Uiso 1.00 C3 C 0.158451082821 0.182136038029 0.976373456129 -0.191852 Uiso 1.00 H4 H 0.156066268055 0 Nov 12, 2019 · Herein, we demonstrate a synergistic approach consisting on radiofrequency plasma to synthesize ammonia in the presence of Ni-MOF-74 as catalyst.
