The exsolution of metallic nanoparticles (NPs) from perovskite oxides is a promising strategy for synthesizing supported catalysts. associated segregation A-site cations on the surface challenging to investigate experimentally and often detrimental catalytic performance. In this work, we found that during in situ Ni-Co bimetallic Pr0.45Ba0.45Mn1–x(Co1/3 Ni2/3)xO3±δ, cation enrichment occurred w...

Praseodymium aluminum oxide (PAO) thin films were grown by atomic layer deposition (ALD) from a new precursor, tris(N,N′-diisopropylacetamidinato) praseodymium, (Pr(amd)3), trimethylaluminum (TMA), and water. Smooth, amorphous films having varying compositions of the general formula PrxAl2–xO3 were deposited on HF-last silicon and analyzed for physical and electrical characteristics. The films ...

Given the narrow band gap enabling excellent optical absorption, increased charge carrier density and accelerated surface oxidation reaction kinetics become the key points for improved photoelectrochemical performances for water splitting over hematite (α-Fe2O3) photoanodes. In this study, a facile and inexpensive method was demonstrated to develop core/shell structured α-Fe2O3 nanorod arrays. ...

We investigate theoretically ferroelastic domain fractions in a heteroepitaxial bilayer consisting of 001 tetragonal PbZrxTi1−xO3 and 001 rhombohedral PbZr1−xTixO3 on a thick 001 passive substrate as a function of the lattice misfit strain between layers and the substrate. By considering the self-strain in each layer and the indirect elastic interaction between the layers, we provide a numerica...

A series of copper doping LaFeO3 perovskite (LaCuxFe1−xO3, LCFO, x = 0.1, 0.4, 0.5, 0.6, 0.9) are successfully synthesized by the sol-gel method under mild conditions. In this study, it is applied for activation peroxymonosulfate (PMS) bisphenol (BPA) removal. More than 92.6% BPA was degraded within 30 min at 0.7 g/L LCFO and 10.0 mM PMS over a wide pH range with limited leaching iron ions. The...

Bismuth ferrite, BiFeO3, is a multiferroic solid that attracting increasing attention as potential photocatalytic material, because the ferroelectric polarization enhances separation of photogenerated carriers. With motivation finding routes to engineer band gap and alignment, while conserving or enhancing properties, thermodynamic, electronic, properties BiCoxFe1?xO3 solutions (x = 0, 0.0625, ...
