A Review on Perovskite-Type LaFeO3 Based Electrodes for CO2 Reduction in Solid Oxide Electrolysis Cells: Current Understanding of Structure–Functional Property Relationships

“…The B-site of LaFeO 3 is commonly doped with transition metal cations due to similar ionic radii between the dopant and iron. The effects of Cr, Mn, Co, Ni, and Cu have been extensively studied; as well, the effects of Mg, Al, Sc, Ti, V, Ga, Nb, Mo, Ru, Rh, Pd, In, Ta, and Ir have also been investigated. ,− ,,,,− The most common dopants are Co and Ni as these late transition metals can change the structure from orthorhombic to rhombohedral. The solid solution between LaFeO 3 and LaNiO 3 is smooth with a composition phase transition around the 50–50 composition from Pnma to R 3̅ c . , This composition commonly displays both phases due to a first order phase transition near room temperature; the structure is orthorhombic below ∼27 °C and rhombohedral above ∼27 °C .…”

Role of Er doping on isoamyl alcohol sensing performance of LaFeO3 microspheres and its prospects in wheat mildew detection

“…The effects of Co, Mn, Ni, Mg, and other elements replacing the Fe atoms on the physicochemical characteristics of LaFeO 3 materials, as well as the sensing properties and enhanced mechanism have been studied. [16][17][18][19] Moreover, some elements have been attempted to replace La atoms at the apex of the cell, including Ba, 20,21 In, 22,23 Ag, 24 Pb, 25 and other lanthanides, while the relevant detection performance has been improved. Zhang et al prepared hexagonal LaFeO 3 , circular NdFeO 3 , and hexagonal star SmFeO 3 through co-precipitation by changing the types of lanthanide metal nitrates in the same reaction system, among which LaFeO 3 exhibited the highest sensitivity for n-propanol.…”

Perovskite Nanoparticles as an Electrochemical Sensing Platform for Detection of Warfarin

“…In the literature, different metal combinations have been developed for the preparation of perovskite structures for specific applications [18][19][20][21][22][23][24][25][26][27]. Additionally, perovskites have been successfully employed in various technological applications, such as catalysts [18][19][20], photocatalysts [28,29], water splitting [30][31][32], supercapacitor [33][34][35], chemical reductions/removal [36][37][38], solar cells [39][40][41], gas sensing [42][43][44], and chemical sensing device development [45][46][47][48][49][50]. Karuppiah et al fabricated graphene nanosheet-wrapped mesoporous LaCeFeMnO 3 perovskite for lithium battery applications [51].…”
