Silver mediation of Fe(VI) charge transfer: Activation of the K2FeO4 super-iron cathode

An unexpectedly large Ag(II) mediation of Fe(VI) redox chemistry improves alkaline Fe(VI) cathodic charge transfer. Combined with a Zn anode, this results in a cell with 3- to 5-fold higher energy capacity than the conventional high-power Zn/MnO2 alkaline battery, and twice that previously observed for Zn/BaFeO4. Both experimental results and a model of this phenomenon are presented. The Ag(II) salt may be introduced as a simple composite of AgO with the Fe(VI) salt. The Fe(VI) super-iron salt K2FeO4 has a high 3e- intrinsic charge capacity (406 mA/g), and is more environmentally benign than the Fe(VI) salt BaFeO4, but had exhibited comparatively poor charge transfer. Successful AgO cathodic activation of both K2FeO4 and BaFeO4 redox chemistry are presented. Various other K2FeO4 activators are also studied. An observed interaction of Fe(VI) with Mn(VII/VI) can improve charge efficiency of a K2FeO4 composite with KMnO4 or BaMnO4, albeit not to the extent observed in an K2FeO4/AgO composite cathode. The extent of an activation effect of oxides, hydroxides, and titanates salts, as well as KMnO4, BaMnO4, AgMnO4, and fluorinated graphites, on the cathodic discharge of K2FeO4 are probed.

AgCuO2 as a novel bifunctional electrocatalyst for overall water splitting in alkaline media

Nanostructured transition metal oxides are among the most prevalent catalysts for the water-splitting process. Herein, AgCuO2 nanoparticles (NPs) are introduced as a novel bifunctional electrocatalyst for both the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) in alkaline media. The catalyst, AgCuO2 NPs, exhibited excellent electrocatalytic activity together with a low overpotential for the overall water-splitting process. The AgCuO2 exhibits excellent electrocatalytic activity with a low onset overpotential of 29 mV for the HER and the onset overpotential of 360 mV for the OER, with superior long-term stability in 1.0 M KOH. The catalyst delivered 10 and 100 mA cm?2 at extremely low overpotentials of 42 and 47 mV for the HER and 10 mA cm?2 at an overpotential of 388 mV for the OER. This work suggests an important reference toward the use of novel bimetallic oxides as highly active and stable bifunctional electrocatalysts for high-performance water splitting.

Thermal decomposition of metal nitrates in air and hydrogen environments

The decomposition of metal nitrates in air has been systematically studied by thermogravimetry. Observed temperature of decomposition (Td) have been inversely correlated to the charge densities (CD) of the metal cations. Due to a back-donation of electronic cloud from the nitrate to an unfilled d-orbital of transition and noble metals, their nitrates generally exhibited lower TdS ( 850 K). The thermal stability/reducibility of metal nitrates in an hydrogen atmosphere has also been studied by temperature-programmed reduction (TPR). Observed reduction temperatures (Tr) for nitrates of the base metals and the noble metals are lower than their Td, i.e., Tr d. The lowering of Tr might be attributed to a spillover of hydrogen to a nitrate moiety through heterolytic (ionic) and homolytic (atomic) dissociation of hydrogen on the respective base and noble metals. The stoichiometry of hydrogen consumption, quantitatively measured from TPR, varied with the group of metal cations. According to the stoichiometry, the end product in the TPR reduction was NH3 (NH2/NNO3-a??4.4) and N2 (NH2/NNO3-a??2.4) for nitrates of the noble and base metals, respectively. The Trs for nitrates of the transition metals are often a??20 K higher than their Tds, and the ratio NH(2)/NNO3- varies widely between 0.7 and 3.2. Their reduction may be triggered by thermal decomposition.

Low-activation solid-state syntheses by reducing transport lengths to atomic scales as demonstrated by case studies on AgNO3 and AgO

Surface characterization study of the thermal decomposition of Ag2CO3

The changes in chemical states and composition of the surface region of a Ag2CO3 powder at various stages during thermal decomposition have been examined using X-ray photoelectron spectroscopy (XPS) and ion scattering spectroscopy (ISS). The near-surface region of the as-received powder consists primarily of Ag2CO3 although some hydrocarbon and alcohol contaminants also are present. A 155°C anneal results in partial decomposition of Ag2CO3 to Ag metal and oxides and reduces the amounts of the C contaminants. An anneal at 170°C causes further decomposition of the Ag2CO3 to Ag metal, Ag2O, and AgO. ISS data indicate that at 205°C oxygen migrates more rapidly to the outermost atomic layer than it desorbs, resulting in an increased oxygen concentration. The AgO species undergoes further decomposition to Ag2O during a 340°C anneal treatment. Between 340 and 430°C the Ag2O decomposes, leaving only Ag metal and subsurface oxygen in the near-surface region of the sample. These results are consistent with temperature-programmed reaction (TPR) data which exhibit a CO2 peak at 260°C and an O2 peak at 420°C. Both the XPS and TPR data indicate that the thermal decomposition of these species are activated since their decompositions occur at temperatures much higher than predicted by equilibrium thermodynamic calculations.

New Method of Describing Monoclinic Silver(I,III)Oxide (AgO), Single Crystal Growing and X-ray Structural Analysis.

A new route for the synthesis of monoclinic AgO has been developed, yielding, for the first time, coarse crystalline samples which apparently do not show deviations from the ideal composition. On electrolysis of aqueous AgF solutions, AgO forms at the anode as crystals of 1. 0 multiplied by 0. 2 multiplied by 0. 05 mm in size. The crystal structure has been refined using single-crystal diffractometer data. The thermal stability recorded by differential thermal and thermogravimetric analysis techniques is improved over samples prepared previously by chemical oxidation.

Coordination chemistry of Cu(II), Co(II), Zn(II) and Ag(I) complexes of isomeric pyridine 2- and 4-carboxamides and their biological activity evaluation

Eight complexes of Cu(II), Co(II), Zn(II) and Ag(I) with rarely studied ligands, N,N-diisopropyl/butylpicolinamide (L1/L2), and N,N-diisopropyl/butylisonicotinamide (L3/L4), have been synthesized and characterized spectroscopically, and their molecular and crystal structures have been reported. Diverse coordination modes of these positional isomers have been discovered, discussed and compared with the limited available literature in light of their respective convergent and divergent nature. All the complexes show stable and extended 1D, 2D or 3D coordination/H-bonded networks owing to a large number of weak C–H?O/X and other intermolecular interactions. Further, the ligands as well as the metal complexes have been evaluated for their antimicrobial activity and have turned out to be potent antimicrobial agents.
