By using pyrazine and hydrofluoric acid, we have synthesized three-dimensional Co-MOF [CoFC4H4N2(SO4)0.5], (1), and Fe-MOF [FeFC4H4N2(SO4)0.5], (2), through a single-step solvothermal method. Further, a series of bimetallic (having both Co and Fe metal centers) MOFs [Co1-xFexFC4H4N2(SO4)0.5] were synthesized with variable concentrations of Fe, and their electrocatalytic performances were analyzed. The optimized amount of Fe significantly impacted the electrocatalytic behavior of the bimetallic MOF toward water oxidation. Particularly, the Co0.75Fe0.25-MOF needs only 239 and 257 mV of overpotential to deliver 10 and 50 mA/cm2 current density, respectively, in alkaline electrolytic conditions. The Co0.75Fe0.25-MOF shows a lower Tafel slope (42 mV/dec.) among other bimetallic MOFs and even the commercial RuO2, and it has excellent durability (with ∼8 mV increases in overpotential after 18 h of electrolysis) and 97.05% Faradaic efficiency, which further evident its catalytic excellency. These findings explore the intrinsic properties of MOF-based electrocatalysts and prospect the suitability for future water electrolysis.

Research paper thumbnail of ChemInform Abstract: Synthesis and Characterization of Robust Three-Dimensional Chiral Metal Sulfates

RSC Advances

Two chiral three-dimensional metal sulfates of the compositions, [NH4]8[Mn8(SO4)12], (1) and [NH4... more Two chiral three-dimensional metal sulfates of the compositions, [NH4]8[Mn8(SO4)12], (1) and [NH4]8[Mg8(SO4)12], (2), of the Langbeinites family have been synthesized under hydro/solvothermal conditions and studied from first principles. Both the two compounds 1 and 2 are isostructural and crystallize in the cubic chiral space group P2(1)3. In the presence of NH4+cations, the frameworks of 1 and 2 have three-dimensional structures formed by corner sharing of metal octahedra and sulfatetetrahedra through M-O-S linkages, which leads to a pinwheel arrangement of metal octahedra surrounded by six sulfatetetrahedra. Both 1 and 2 are observed to retain their structures upon thermal decomposition of ammonium ion resulting into compositions [H]8[Mn8(SO4)12] and [H]8[Mn8(SO4)12] respectively. Magnetic measurement of 1 shows paramagnetic behavior and hydrogen adsorption of 1 and 2 shows 0.45 and 0.7 wt% respectively at 77 K. The proton conductivity of 1 under various relative humidity (RH) sh...
