Special Issue Information

Dear Colleagues,

Perovskite materials represent an emerging and exciting class of inorganic materials that have attracted worldwide research interest and have been widely implemented in energy storage and conversion. The intriguing magnetic, catalytic, optic, and optoelectronic properties of metal halide and metal oxide perovskites, such as semiconducting, ferroelectric, piezoelectric, magnetoresistance, superconductivity, and catalytic activity, make them attractive and promising candidates for electrocatalysis, energy conversion and storage, information technology, spintronic devices, and much more. For instance, the certified power conversion efficiency of metal halide perovskite solar cells experienced an over 5-fold increase to 25.2% in the past decade.

In this context, we aim to present state-of-the-art research on perovskite materials in this Special Issue—from novel synthetic methods to fundamental property investigations and potential applications in catalysis, devices, and others—in the form of original research articles or critical reviews.

We look forward to receiving your contributions.

KNbO3 single crystals are grown by the self-flux method using K2CO3 as a flux, but often suffer from discolouration. In this work, KNbO3 single crystals were grown by the flux method using KBO2 as a flux. KNbO3 powder was prepared by the solid-state reaction of K2CO3 and Nb2O5. KBO2 was fabricated by the reaction of K2B4O7·4H2O and K2CO3. Single crystals of KNbO3 were grown in a Pt crucible and the structure and dielectric properties of the single crystals were investigated. X-ray diffraction showed the KNbO3 single crystals to have an orthorhombic Cmm2 perovskite unit cell at room temperature. The existence of ferroelastic domains was revealed by transmission electron microscopy. Electron probe microanalysis showed the single crystals to be stoichiometric and contain small amounts of B. Differential thermal analysis, Raman scattering and impedance spectroscopy were used to study the phase transitions. KBO2 may be a suitable flux for the growth of KNbO3 single crystals. Full article
