Lead-halide perovskites have demonstrated outstanding optical, electrical, and spintronic properties made significant breakthroughs in many fields, especially solar cells. Although substantial efforts been devoted to developing...
Perovskite oxides with general formula AMO3 have a large variety of applications as dielectrics and piezoelectrics, ferroelectrics and/or ferromagnetic materials, among others. Rare earth and alkaline earth metal perovskites are useful as catalysts for hydrogen generation, as oxidation catalysts for hydrocarbons, and as effective and inexpensive electrocatalysts for state-of-the-art fuel cells,...
Intensive development of organometal halide perovskite solar cells has lead to a dramatic surge in power conversion efficiency up to 20%. Unfortunately, the most efficient perovskite solar cells all contain lead (Pb), which is an unsettling flaw that leads to severe environmental concerns and is therefore a stumbling block envisioning their large-scale application. Aiming for the retention of f...
Catalytic tests to assess the performance of mixed perovskite-type oxides (La0.9Ca0.1FeO3-δ, La0.6Ca0.4FeO3-δ, Nd0.9Ca0.1FeO3-δ, Nd0.6Ca0.4FeO3-δ, Nd0.6Ca0.4Fe0.9Co0.1O3-δ, Nd0.6Ca0.4Fe0.97Ni0.03O3-δ, and LSF) with respect CO oxidation are presented as well characterization materials by XRD SEM. Perovskites a highly versatile class due their flexible composition ability incorporate dopants easi...
