Advances in the knowledge of the double perovskites derived from the conformation and substitution of the material Sr2MgMoO6-δ as anode with potential application in SOFC cell

Heterostructured 2D material-based electro-/photo-catalysts for water splitting

“…159,160 Additional stabilization steps may be necessary for maintaining the structural integrity of a 2D perovskite. Some examples of 2D perovskites that have been investigated for HER catalysis include lead halide perovskites (e.g., CsPbBr 3 ), 161,162 layered double perovskites (e.g., Sr 2 MgMoO 6 ), 163,164 and Ruddlesden-Popper perovskites (e.g., Sr 2 Nb 2 O 7 ). 165 These materials have different structural and compositional features, and their HER catalytic activity may depend on various factors such as exposed surface area, electronic structure, and surface chemistry.…”

Probing the Transport Properties, Electrophoretic Deposition, and Electrochemical Performance of La2–xSmxCe2O7 Ceramics for IT-SOFCs

“…This process is commonly referred to as carbon deposition or coking. − Apart from Ni, some other catalysts such as Cu, Fe, Pd, Pt, and Rh were also studied to avoid the coking phenomena when operating in methane fuel. − However, these catalysts limit the practical implications in terms of cost and processability despite the improvement in SOFC performance with carbon-containing fuels. Apart from metallic catalysts, several mixed ion and electron-conductive (MIEC) materials were also studied such as Sr­(Ti 0.3 Fe 0.7 )­O 3−δ , Sr 2 MgMoO 6−δ -related materials, − Sr 2 FeMoO 6−δ Pr 0.8 Sr 1.2 (Co,Fe) 0.8 Nb 0.2 O 4+δ , Sr 3 Fe 1.3 Mo 0.5 N i0.2 O 7−δ , and so on, for methane reforming or hydrocarbon fuel environment. These materials have their own limitations such as lower electronic conductivity and lower catalytic activity compared to Ni-based anodes .…”

Co-improving the electrocatalytic performance and H2S tolerance of a Sr2Fe1.5Mo0.5O6−δ based anode for solid oxide fuel cells

“…Mixed ionic electronic conductors (MIECs), with dual oxygen ion and electron conductivities, especially perovskite metal oxides, such as ABO 3 , A 2 BB′O 6− δ and AA′B 2 O 5+ δ , have received significant research attention in the past few decades. 6–8 The B-site of the perovskite oxide is usually occupied by one or more transition metals (Ti, Cr, Mn, Fe or Mo), such as La 1− x Sr x TiO 3+ δ , 9,10 La 0.75 Sr 0.25 Cr 0.5 Mn 0.5 O 3− δ , 11 PrBaMn 2 O 5+ δ , 12 Sr 2 MgMoO 6− δ (ref. 13) and Sr 2 Fe 1.5 Mo 0.5 O 6− δ .…”
