Nanocrystalline, mesoporous NiO/Ce0.9Gd0.1O2−δ thin films with tuned microstructures and electrical properties: in situ characterization of electrical responses during the reduction of NiO

Full ceramic micro solid oxide fuel cells: towards more reliable MEMS power generators operating at high temperatures

“…Two main strategies appear to be the most suitable for fabricating more reliable thin lm anodes for mSOFCs, namely (i) the implementation of cermets based on stable ceramic scaffolds or (ii) the use of more stable fully ceramic anode materials. Only a few studies dealing with thin lm cermet anodes (below 1 mm) have been published until now, 19,[65][66][67][68][69] and among them, there is only one report on their implementation on mSOFC membranes. 19 19 fabricated a Ru-CGO composite observing a quite fast degradation of the so-fabricated mSOFC with time (62% of the initial power density within 3 h).…”

Controlled Synthesis of a Hexagonal‐Shaped NiO Nanocatalyst with Highly Reactive Facets {1 1 0} and Its Catalytic Activity

“…Very recently, surface-controlled synthesis of metal oxide nanocrystals has been performed to enhance their physicochemical properties. [15,16] In particular, nickel oxide nanocrystals are very demanding owing to their potential based on magnetic, [17] electrical, [18] and catalytic properties, [19][20][21] and applications in dye-sensitized solar cells, [22] super capacitors, [23,24] Li ion batteries, [25,26] fuel cells [27] and gas-sensing materials. [28] During the past several decades, many synthetic strategies have been developed including the hydrothermal process, sol-gel and thermal decomposition methods for the preparation of nanosheets, hexagonal, nanotube, and nanowire morphology of NiO materials.…”

Synthesis, characterization and electrical properties of La0.7Sr0.3Co0.2Fe0.8O3/Gd–CeO2 thin films (≤500 nm)

“…A single arc is observed whatever be the heating temperature and is attributed to the mesoporous thin lm response. As it has been observed for other mesoporous thin lms, 34,35 the contribution related to the grains cannot be distinguished from the grain boundaries and/or the porosities. Thus, the diameter of the semi-circle (from the origin to the intercept with the x-axis at the lowest frequencies) corresponds to the total electrical resistance of the lms.…”
