Room temperature fabrication of highly proton conductive amorphous zirconia-based thin films achieved through precise nanostructure control

Abstract

YSZ thin films with controlled microstructure were fabricated without annealing process. The microstructure strongly depended on the oxygen partial pressure during the deposition, and the proton conductivity also varied significantly.

Symmetry-induced modulation of proton conductivity in Y-doped Ba(Zr,Ce)O3: insights from Raman spectroscopy

“…3,4 Proton-conducting thin lms exhibit higher proton conductivity than bulk materials at high temperatures and thus receive considerable attention. [5][6][7] In particular, epitaxial thin lms with strong preferred orientation exhibit a single crystalline structure and thus can effectively mitigate the grain boundary density and promote long-range proton transport. 8,9 Therefore, epitaxial lms are ideal systems for the investigation of proton transport in the crystal lattice.…”

Selective Detection of CO Using Proton-Conducting Graphene Oxide Membranes with Pt-Doped SnO2 Electrocatalysts: Mechanistic Study by Operando DRIFTS

“…Several chemical sensing techniques based on electrochemical, – chemiresistive, – and catalytic combustion – mechanisms have been employed to detect CO at ppm concentrations in air. Among these, solid-state electrochemical gas sensors using ion conductors are promising in terms of their high sensitivity to combustible gases, simple structure, and lower temperature operation. , Potentiometric detection of gaseous species has been extensively studied using proton-, – oxide-, – and sodium-ion – conducting solids.…”
