  Efficient supercapattery behavior of mesoporous hydrous and anhydrous cobalt molybdate nanostructures

  摘要：

  Hydrous forms of cobalt molybdate binary metal oxide nanoaggregates were synthesized via a simple chemical co-precipitation technique. The subsequent heat treatment at 400 degrees C converted the sample into anhydrous cobalt molybdate (CoMoO4) with mesoporous nanostructure. The anhydrous cobalt molybdate possess surface area and pore volume of 63.92 m(2)g(-1) and 0.1802 cm(3)g(-1) which is much higher than the hydrous cobalt molybdate (1.215 m(2)g(-1) and 0.0072 cm(3)g(-1)). The electrodes designed using these materials exhibited a battery-like behavior with maximum specific capacity of 97 Cg(-1) and 177 Cg(-1) for hydrous and anhydrous cobalt molybdate samples respectively. In addition, a supercapattery was fabricated utilizing anhydrous cobalt molybdate//activated carbon electrodes, which showed maximum specific capacity value of 64 Cg(-1) at 1 Ag-1 discharge specific current and showed better specific energy similar to 18.89 Whkg(-1) for a specific power of 1.06 kWkg(-1). Moreover, the supercapattery exhibited good capacity retention similar to 93% after 5000 charge/discharge cycles. (C) 2019 Elsevier B.V. All rights reserved.

  Sub-micrometric β-CoMoO4 rods: optical and piezochromic properties

  摘要：

  Sub-micrometric β-CoMoO4 rods have been obtained after thermal treatment of CoMoO4·H2O previously prepared by the precipitation method. The color of the sub-micrometric particles has been investigated through diffuse reflectance in the VIS-IR range and the spectra have been compared with those corresponding to samples with larger isotropic particles. The O2−→Mo6+ charge transfer band shifts to the UV region with decreasing the particle size, revealing a more covalent bond. This can be justified under the consideration of a higher proportion of surface-atoms in sub-micrometric particles that present lower coordination number. The piezochromic behavior of the sub-micrometric β-CoMoO4 rods has been investigated. As the sub-micrometric size of the particles stabilizes the low-coordination phase (β-phase), the transition pressure to the α-phase is higher in comparison with that corresponding to larger particles. In addition, it was not possible to obtain a 100% transformation of the β-phase in the sample with sub-micrometric particles. A similar temperature influence on the transition pressure regardless of particle size has also been observed.

  A comparison of the reactivity of lattice nitrogen in Co3Mo3N and Ni2Mo3N catalysts

  摘要：

  The influence of nitriding conditions upon the ammonia synthesis activities and structures of cobalt molybdenum and nickel molybdenum-based catalysts has been compared. Ammonolysis of cobalt molybdate is observed to produce a more active catalyst than H-2/N-2. pre-treatment. Post-reaction XRD analysis shows a pure Co3Mo3N phase in the former case and a mixed phase, containing some Co3Mo3N, in the latter. Both ammonolysis and N-2/H-2 pretreatment of nickel molybdate lead to a mixture of Ni2Mo3N and Ni, with the latter pretreatment leading to catalysts of higher activity. The reactivity of lattice nitrogen in eta-6 carbide Structure Co3Mo3N and the beta-Mn Structure Ni2Mo3N has been investigated. In both cases, lattice nitrogen is found to be reactive towards both H-2 and C6H6 and comparisons demonstrate Co3Mo3N to be the more reactive. For Co3Mo3N, reaction with benzene yields Co3Mo3C and graphite whereas a carbonitride and graphite is produced with Ni2Mo3N. In the case of reaction with H-2, the nickel molybdenum system reacts to form Ni2Mo3N1-x, whereas comparable conditions with Co3Mo3N produce a novel Co6Mo6N phase. (c) 2008 Elsevier B.V.

  Lattice nitrogen within the catalyst Co3Mo3N is both reactive and likely highly mobile, enabling potential novel nitrogen transfer pathways; evidence suggests that loss and subsequent regain of lattice nitrogen in the system reversibly cycles through the previously unknown nitride, Co6Mo6N.

  reactivities of a series of ternary and binary molybdenum nitrides have been compared. Data have been obtained for the catalytic synthesis of ammonia at 400 °C and ambient pressure using a 3:1 H2:N2 mixture. Amongst the ternary nitrides, the mass normalised activity is in the order Co3Mo3N>Fe3Mo3N⪢Ni2Mo3N. For the binary molybdenum nitrides, the ammonia synthesis activity is significantly lower than that
