Three-dimensional hierarchical honeycomb-like activated porous carbon pillared ultrathin Ni(OH)2 nanosheets (Ni(OH)2 NSs@HAPC) for use as supercapacitor materials were facilely synthesized. With an aid of pine cone flowers as a biomass source, HAPC conducting scaffolds were prepared by the alkali treatment and pyrolysis methods under an inert gas atmosphere. Subsequently, the Ni(OH)2 NSs were s...

Title of Document: MODEL DEVELOPMENT FOR GADOLINIADOPED CERIA-BASED ANODES IN SOLID OXIDE FUEL CELLS Lei Wang, Doctor of Philosophy, 2014 Directed By: Professor Gregory S. Jackson, Department of Mechanical Engineering Intermediate temperature (500 700 °C) solid oxide fuel cells (IT-SOFCs) with gadolinia-doped ceria (GDC) electrolytes have significant commercial potential due to reduced material...

A mathematical model is presented for the galvanostatic deposition of Ni(OH)2 films in stagnant Ni(NO,), solutions. The objective is to quantify the anomalous deposition behavior reported previously in which the utilization of the electrochemically generated OW species decreased drastically as the concentration of Ni(N03)2 increased beyond 0.1 M. For example, as the Ni(NO,)2 concentration incre...

An enhanced CO 2 electrolysis current density of 2.20 A cm −2 @ 1.5 V at 1123 K is achieved for LSFM electrodes using Fe catalyst rather than Ru, Ni, and Co catalysts.

For SOFCs to be main means of power generation, they should be able to exploit wide variety of fuels. Among Ni-cermets, Ni-YSZ is the state-of-the-art materials for the anode in SOFC which is the fuel electrode. But sulphur impurity present in different gaseous fuels (e.g Biogas), depending on its concentration, is highly poisonous to the stability and electrochemical performance of the Ni cata...

The catalytic performance and the stability of water electrolysis system have perplexed practical splitting water. Herein, 3D-printed metallic electrodes with Janus porosity are reported, which can achieve efficient bubble emission provide high surface area. After a further one-step treatment, catalysts Ru–Ni(OH)2 Fe–Ni(OH)2 nanoarrays in situ grown on electrodes. Theoretical calculations syste...
