Methane Combustion and CO Oxidation on Ag-Doped LaMn0.8Cu0.2O3±δ Mixed Oxides Prepared by Pechini and Sol–Gel Methods

Ag/Pt Core-Shell Nanoparticles on Graphene Nanocomposite for Effective Anodic Fuels Electro-oxidation

The nanocomposite consists of the Ag as a core and Pt as shell on the surface of graphene nanosheets (Ag/Pt-G) was synthesized with a simple method and used as a novel electrochemical platform for an efficient catalyst for oxidation of the ethanol, methanol and formic acid. The morphology and electrochemical properties of Ag/Pt-G nanocomposite were investigated by TEM, X-ray diffraction, and vo...

Thermal expansion of doped lanthanum gallates

Thermal expansion of several compositions of Sr and Mg-doped LaGaO3 including an A-site deficient composition (La0⋅9Sr0⋅1)0⋅98(Ga0⋅8Mg0⋅2)O2⋅821 were measured in the temperature range from 298 to 1273 K. The effect of doping on thermal expansion was studied by varying the composition at one site of the perovskite structure (either A or B), while keeping the composition at the other site invaria...

Electrochemical recovery of silver from waste aqueous Ag(I)/Ag(II) redox mediator solution used in mediated electro oxidation process

−The paper presents a process for the electrochemical recovery of silver(Ag) by electro deposition on the electrode surface from the waste solutions of Ag(I)/Ag(II) redox system in nitric acid medium used for the mediated electrochemical process. Electrochemical recovery was carried out in an undivided cell with DSA-O2 electrodes at room temperature condition. At an optimized current density of...

Thermoelectric Properties of Lanthanum-Doped Europium Titanate

The thermoelectric properties of lanthanum-doped polycrystalline perovskite-type europium titanate were measured from room temperature to 900K and compared to those of MTiO3 (M 1⁄4 Ca, Sr, Ba). The differences in the titanates were calculated in terms of the differences of A-site ion and Ti–O distance that determined the covalent bonding strength. The A-site ion appeared to have little influenc...
