The phase formation of Ni-Ce composites onto a carbon steel electrode was investigated using electrochemical deposition. The anticorrosive properties of composite coating in 0.1 mol L HCl solution were studied by Tafel polarization and electrochemical impedance spectroscopy (EIS). Incorporation of CeO2 particles into the Ni matrices was found to improve corrosion resistance of pure Ni coatings....

CeO2/La2Zr2O7/Ni piled-up structure is a very promising architecture for YBa2Cu3O7 (YBCO) coated conductors. We have grown YBCO/CeO2/ LZO/Ni epitaxial structures by metalorganic decomposition (MOD) and metalorganic chemical vapour deposition (MOCVD) methods. The crystallographic quality of the CeO2 layer is not well determined by conventional X-Ray Diffraction (XRD) due to the superposition of ...

NieS/CeO2 electrodes have been prepared by a composite electrodeposition technique using nickel sulfaminate bath containing suspended microor nano-sized CeO2 particles. The composite electrodes exhibit a high activity for the hydrogen evolution reaction (HER) in alkaline solutions, most likely due to the synergistic effects between Ni and CeO2, as well as the increased surface area of the elect...

Monometallic Pd and Ni bimetallic Pd–Ni catalysts supported on CeO2 are prepared via mechanochemical conventional incipient wetness impregnation methods tested for the production of syngas by partial oxidation methane. Compared with monometallic Ni/CeO2 Pd/CeO2, Pd–Ni/CeO2 show considerable higher methane conversion yield. Additionally, ball milling produce at lower temperature. Different prepa...

CeO2-MO x (M = Cu, Co, Ni) composite yolk-shell nanospheres with uniform size were fabricated by a general wet-chemical approach. It involved a non-equilibrium heat-treatment of Ce coordination polymer colloidal spheres (Ce-CPCSs) with a proper heating rate to produce CeO2 yolk-shell nanospheres, followed by a solvothermal treatment of as-synthesized CeO2 with M(CH3COO)2 in ethanol solution. Du...

CeO2/La2Zr2O7 composite buffer layers were deposited on Ni-W tapes using chemical solution method. YBa2Cu3O7-x (YBCO) films were then deposited on the CeO2/La2Zr2O7 composite buffer layers using a low-fluorine solution route. Effect of the annealing temperature and annealing atmosphere on the texture of the CeO2 layers was investigated. It was found that CeO2 film annealed at 1000°C under the a...

Activated carbons (ACs) derived from cork wastes were for the first time used as supports CO2 methanation catalysts. Cork (natural-N and processed-P) physically activated under N2/H2O(v) atmosphere at 800 °C to obtain corresponding AC (ACN ACP, respectively). Ni Ni-CeO2 catalysts prepared by loading ACs with 15 wt % (Ni/AC) or Ce (NiCe/AC) incipient wetness impregnation co-impregnation, respect...

Abstract Herein, the promotion effect of only 0.3 wt% indium on 3% Ni/Al2O3 and Ni/CeO2-Al2O3 catalysts prepared by deposition-precipitation over a commercial alumina CeO2-modified support was studied. Catalyst characterization XRD, TPR, XPS, TEM, CO-DRIFTS performed. The catalytic properties were investigated coke formation analyzed under temperature ramped CH4-decomposition in Dry Reforming M...

Integrated CO2 capture and utilisation (ICCU) is a promising strategy for restricting carbon emissions achieving neutrality. Bifunctional combined materials (BCMs), containing adsorbents active catalysts, are widely applied in this process. Producing syngas via reverse water–gas shift reaction (RWGS) integrating with Fischer-Tropsch (F-T) synthesis an attractive valuable route. This work invest...
