Ion Beam Sputtering Deposition to Prepare Pt/ZrO2 Active Layer for Hydrogen Evolution and Oxidation Reaction

ChemElectroChem, Volume 13, Issue 9, 5 May 2026.
Pt@ZrO2 thin films are fabricated by ion beam sputtering as compact, binder‐free electrodes with low Pt loading (0.0475 mg·cm−2). The intimate mixing between the noble metal and the ceramic support enhances intrinsic catalytic activity toward alkaline hydrogen evolution, allowing a significant reduction in precious metal loading while maintaining ...

Synthesis and Properties of Novel Calcia-Stabilized Zirconia (Ca-SZ) with Nano Calcium Oxide Derived from Cockle Shells and Commercial Source for Dental Application

Applied Sciences, 2020
Various oxides are used to stabilize zirconium oxide (ZrO2), but their superior hardness causes wear of the machining tool. Calcia-doped zirconia has been studied but reports on properties suitable for dental application are lacking.
