Ionic transport dynamics underpins the functionality of most energy storage and conversion technologies. Yttrium-doped barium zirconate (Y-BZO) has attracted attention as a promising electrolyte for proton-conducting solid oxide fuel cells (PC-SOFCs), which stems from its high proton conductivity and excellent chemical stability at intermediate temperatures (400-700°C) [1]. The Grotthuss mechan...

Yttrium-doped barium zirconate is one of the fastest solid-state proton conductors. While previous studies suggest that proton–tuples move as pairs in yttrium-doped zirconate, a systematic catalog possible close proton–tuple moves missing. Such essential to simulating dual conduction effects. Density functional theory with Perdew–Burke–Ernzerhof utilized obtain total electronic energy for each ...

The emission of wide band photoluminescence showed a synergic effect on barium zirconate and barium titanate thin films in alternate multilayer system at room temperature by 488 nm exiting wavelength. The thin films obtained by spin-coating were annealed at 350, 450, and 550 degrees C for 2 h. The X-ray patterns revealed the complete separation among the BaTiO3 and BaZrO3 phases in the adjacent...

We developed an Fe2O3/BZY (yttrium-doped barium zirconate)–RuO2 (Fe/BZY–RuO2) cathode catalyst, which was applied to the electrochemical synthesis of NH3 using a proton-conducting electrolyte, CsH2PO4/SiP2O7, at 220 °C and ambient pressure.

So far, the antibacterial activity of some organic and inorganic compounds has been studied. Barium zirconate titanate [Ba(ZrxTi₁-x)O₃] (x = 0.05) nanoparticle is an example of inorganic materials. In vitro studies have provided evidence for the antibacterial activity of this nanoparticle. In the current study, the nano-powder was synthesized by sol-gel method. X-ray diffraction showed that the...

Wetting of the pore walls of porous templates is a simple and convenient method to prepare nanotubes. Ferroelectric lead zirconate titanate and barium titanate nanotubes were fabricated by wetting of porous silicon templates of polymeric precursors. The ferroand piezoelectric properties of an individual ferroelectric either of a PZT or a BaTiO3 nanotube were electrically characterized by measur...

As a low-cost alternative to noble metals, Cu plays an important role in industrial catalysis, such as water-gas shift reaction, methanol or ethanol oxidation, hydrogenation of oils, CO among many others. An step optimizing catalyst performance is control nanoparticles size, distribution, and the interface with support. While proton conducting perovskites can enhance metal catalytic activity wh...
