Preparation of methanation catalysts for high temperature SOEC by β-cyclodextrin-assisted impregnation of nano-CeO2 with transition metal oxides

Nanotechnologies in ceramic electrochemical cells

“…During metal-ion infiltration, Błaszczak et al investigated the influence of b-cyclodextrin on metal NPs. 317 They found that smaller metal oxides could be obtained on the substrate surface, resulting in increased catalytic activity and enhanced durability of the composite catalysts. To date, infiltration has been widely used in the research of air electrodes.…”

CuO, MgO, and ZrO₂ Loading on HZSM5 by Deposition-precipitation: Study of Crystallinity, Specific Surface Area, and Morphology

“…The metal oxides do not form agglomerates because they are dispersed on the support (HZSM5), thereby establishing metal oxides-support interactions and reducing metal oxides-metal oxides interactions. Therefore, the metal oxides will separate from their group (reduced agglomeration) [32].…”

Pr2Ni0.8Co0.2O4+δ impregnated La0.6Sr0.4CoO3−δ oxygen electrode for efficient CO2 electroreduction in solid oxide electrolysis cells

“…13 Solution impregnation is a technique of xing high surface area catalytic particles on ceramic support material, which is considered an effective method to improve the performance of cell electrodes. [14][15][16] The most widely used Ruddlesden-Popper (R-P) type anode material is Ln 2 NiO 4+d (Ln = La, Nd, Pr). 17 It can be regarded as a special structure composed of a LnO rock salt layer and LnNiO 3 perovskite layer, which makes it not only have higher electronic conductivity of perovskite material but also higher oxygen ion conductivity because there is a large amount of interstitial oxygen in LnO rock salt layer.…”
