Fe(iii) phytate metallogel as a prototype anhydrous, intermediate temperature proton conductor.
نویسندگان
چکیده
A proton conducting metallogel [FNPA; ferric nitrate (FN)-phytic acid (PA)] is synthesized by immobilizing a protogenic ligand (phytic acid) using iron(iii) nitrate in DMF. The xerogel shows high proton conductivity of 2.4 × 10-2 S cm-1 at 120 °C, the best value known among all metal organic materials (MOMs). Marking the first such attempt in MOMs, an electrode made using the xerogel showed a power density of 0.94 mW cm-2 at 0.6 V under dry fuel cell conditions.

Incorporation of imidazole within the metal-organic framework UiO-67 for enhanced anhydrous proton conductivity.
Imidazole was introduced into the channels of the metal-organic framework UiO-67 using an evaporation method. The imidazole@UiO-67 composite presents a high proton conductivity of 1.44 × 10(-3) S cm(-1) at 120 °C under anhydrous conditions. With a low activation energy at high temperatures (0.36 eV), the hybrid material can be regarded as a superionic conductor.
متن کاملDehydrogenation of anhydrous methanol at room temperature by o-aminophenol-based photocatalysts
Dehydrogenation of anhydrous methanol is of great importance, given its ubiquity as an intermediate for the production of a large number of industrial chemicals. Since dehydrogenation of methanol is an endothermic reaction, heterogeneous or homogeneous precious-metal-based catalysts and high temperatures are usually required for this reaction to proceed. Here we report the photochemical dehydro...
متن کاملDiscovery of Dark pH-Dependent H+ Migration in a [NiFe]-Hydrogenase and Its Mechanistic Relevance: Mobilizing the Hydrido Ligand of the Ni-C Intermediate
Despite extensive studies on [NiFe]-hydrogenases, the mechanism by which these enzymes produce and activate H2 so efficiently remains unclear. A well-known EPR-active state produced under H2 and known as Ni-C is assigned as a Ni(III)-Fe(II) species with a hydrido ligand in the bridging position between the two metals. It has long been known that low-temperature photolysis of Ni-C yields distinc...
متن کاملFlexibility of Hydrogen Bond and Lowering of Symmetry in Proton Conductor
In order to investigate why crystal symmetry lowers with increasing temperature by phase transition of TII–III (=369 K) in Cs3H(SeO4)2, in spite of the fact that crystal symmetry in the high-temperature phase of many ionic conductors becomes higher by the phase transition, we have studied the relation between the change in crystal symmetry and the appearance of proton motion. It was found from ...
