Perovskite Structured Materials: Synthesis, Structure, Physical Properties and Applications

Abstract

There is a constant need for newer exceptional materials with better than ever properties to achieve new prerequisites of the future society and progress inventive industrial improvement. The potential to combine these oxides in composite structures to produce multifunctional materials has rekindled interest in perovskites (ABO3) compounds over the past 10 years. Because of its intriguing characteristics, such as ferroelectricity, piezoelectricity, superconductivity, multiferroicity, photocatalysis, enormous magnetoresistance, dielectric, ionic conduction characteristics, etc., a huge variety of perovskite types have been thoroughly explored. Current applications for perovskite solids include electronics, geophysics, astronomy, nuclear, optics, medicine, the environment, etc. Perovskite compounds have distinctive features that make them suitable for a variety of commercial and technological applications, including capacitors, non-volatile memories, photo-electrochemical cells, catalysts in contemporary chemistry, actuators and sensors, ultrasonic and underwater devices, drug delivery, spintronics devices, tunable microwave devices, and many others. Potential applications for nanoscale perovskites include energy storage, fuel cells, nanomedicine, molecular computing, nanophotonics adjustable resonant devices, catalysts, and sensors. Nanoscale perovskites have intriguing features that are comparable to or better than those of bulk perovskites. This review includes topics such as perovskite structured materials’ chronology, classification, production, crystal structure, special physical properties, and applications.

Advancing energy storage and supercapacitor applications through the development of Li+-doped MgTiO3 perovskite nano-ceramics

“…Perovskite titanates find applications in various fields, such as optoelectronics, and lithium-ion batteries, gas sensing, among others. The thermal stability of the perovskite MTiO 3 is a major factor that affects the properties of the perovskite, where some perovskite decomposes into spinel structures and the rutile phase 9 , 10 . MgTiO 3 is a highly thermally stable perovskite with a high tolerance factor; it possesses good mechanical resistance and stability even in corrosive environments 11 – 13 .…”

Perovskite Oxides: Syntheses and Perspectives on Their Application for Nitrate Reduction

“…These features lead to the formation of two key types of oxide phases, namely the ternary ABO 3 type and their solid solutions and the complex modern type compounds (AB′ x B″ y ) O 3 , where B′ and B″ are two separate elements in numerous oxidation states and x + y = 1. Subsequently, according to their oxidation states, ternary oxides can be further categorized into oxygen and cation-deficient species and A 1+ B 5+ O 3 , A 2+ B 4+ O 3 , A 3+ B 3+ O 3 …”
