This paper presents a proof-of-concept study and demonstrates the next generation of “smart” catalyst material, applicable to high temperature catalysis electro-catalysis such as gas processing for solid oxide cells.
The perovskite-type mixed oxide La0.3Sr0.55Ti0.95Ni0.05O3−δ (LSTN) is demonstrated to exhibit the remarkable property of structural regeneration, where Ni can be reversibly exsoluted from host perovskite lattice resulting in a regenerable catalyst for solid fuel cell anode applications. Results catalytic tests water gas shift reaction and electrochemical investigations on button-sized demonstrate redox stability LSTN, its potential application cells, ability recover activity completely after...
Abstract The production and optimisation of screen printing (SP) pastes containing La 0.58 Sr 0.42 Co 0.21 Fe 0.79 O 3 – δ 0.61 0.41 0.19 (LSCF) were investigated. application these nanopowders is supposed to improve the cathode's microstructure increase its mechanical strength. Thirty seven LSCF carried out with variation in binders, dispersants different particle size distribution. rheological behaviour was It found that commercially available dispersant Solsperse 3000 resulted best...
Combined chemical analyses of both the surface and bulk industrial catalysts is a significant challenge, because all microanalysis methods reveal either or properties but not both. We demonstrate combined use hard soft X‐ray photoelectron spectroscopy (XPS) as powerful, practical, nondestructive tool to quantitatively analyze composition at surfaces (~1 nm) subsurfaces/bulk (~10 for catalysts. The surface‐bulk differentiation achieved via an exchangeable anode system, where Al (Kα, 1486.6...
Perovskite derived Ni catalysts offer the remarkable benefit of regeneration after catalyst poisoning or particle growth through reversible segregation from perovskite-type oxide host. Although this property allows for repeated regeneration, improving stability towards sulfur by H2S is highly critical in solid fuel cells. In work Mn, Mo, Cr and Fe were combined with at B-site La0.3Sr0.55TiO3±δ to explore possible benefits two transition metals tolerance. Catalytic activity tests water gas...
