The photocatalytic activity of materials for water splitting is limited by the recombination of
photogenerated electron–hole pairs as well as the back-reaction of intermediate species …

AgNbO3 exhibits “peculiar” anti-/ferroelectricity and narrow bandgap semi-conductivity that
lead to active responses to different types of external stimuli, including electric fields, light …

BiFeO3 nanoparticles prepared by a modified Pechini method display strong size-
dependent properties. The rhombohedral distortion from cubic structure is reduced by …

Crystal structure and dielectric property of ferroelectric materials may depend on the sample
size at nano-or submicrometric scale. This phenomenon is called “size effect” in …

Size‐dependent lattice expansion of nanoparticles is observed for many ionic compounds,
including metal oxides, while lattice contraction prevails for pure metals. However, the …

The concept of high entropy ceramics opens up the possibility to optimise the properties of
relaxor ferroelectrics with Aurivilius phase structures. In this paper, two new multi-element …

People are looking for alternative and clean energy sources to replace the fossil energy. H
2, as a green fuel with high combustion value, has been produced via photocatalytic by …

Searching for a new approach in environmental remediation in terms of dye degradation is
important in industrialized society. In this work, ferroelectric Ba2. 5Sr2. 5Nb8Ta2O30 (BSNT) …

Heterostructured powders composed of microcrystalline PbTiO3 cores coated with
nanostructured TiO2 shells were prepared by a sol–gel method. When exposed to visible …

The ferroelectric and magnetic behaviour of multiferroic BiFeO 3 nanoparticles has been
studied using piezoresponse force microscopy (PFM), Mössbauer spectroscopy and SQUID …
