The focus of this study is the measurement and understanding of the sulfur poisoning phenomena of Ni/gadolinium-doped ceria (CGO) based solid oxide fuel cells (SOFC). Cells with Ni/CGO10 and NiCu5/CGO40 anodes were characterized by using impedance spectroscopy at different temperatures and H2 /H2 O fuel ratios. The short-term sulfur poisoning behavior was investigated systematically at temperat...
Herein, we report synthesis of nitrogen-doped graphene (NGr) interpenetrated 3-D Ninanocage (Ni-NGr) electrocatalyst by simple water-in-oil (w/o) emulsion technique for oxidation of water-to-dioxygen. Correlation of adsorption of NGr and subsequent interpenetration through the specific surface plane of nickel particles as well as concomitant interaction of N, C, with Ni at a nano-regime have be...
Herein, we explore the immobilization of nickel on various carbon supports and their application as electrocatalysts for the oxidation of propargyl alcohol in alkaline medium. In comparison with massive and nanoparticulated nickel electrode systems, Ni-doped nanoporous carbons provided similar propargyl alcohol conversions for very low metallic contents. Nanoparticulated Ni on various carbon su...
Bond paths and the bond critical point properties (the electron density (rho) and the Hessian of rho at the bond critical points (bcp's)) have been calculated for the bonded interactions comprising the nickel sulfide minerals millerite, NiS, vaesite, NiS(2), and heazlewoodite, Ni(3)S(2), and Ni metal. The experimental Ni-S bond lengths decrease linearly as the magnitudes of the properties each ...
Abstract This experiment addressed the effect of Nickel-doped on dielectric, ac conductivity, and optical properties pure doped Zn (1−x) Ni x O (x = 0, 3 6%) nanostructures. The un-doped Ni-doped ZnO nanostructures were synthesized using co-precipitation. In this paper, frequency-dependent dielectric electrical conductivity examined at various temperatures ranging from 320 K to 460 an LCR meter...
