Several SrCoOx-based electrochemical devices have been proposed, but solid-state protonation from SrCoO2.5 to HxSrCoO2.5 (x = 1, 1.5, and 2) at room temperature has not been demonstrated thus far due to the absence of an appropriate solid electrolyte. I demonstrated a solid-state electrochemical protonation of SrCoO2.5 using mesoporous amorphous 12CaO・7Al2O3 (CAN) film as the solid electrolyte. The crystalline phase discretely changed from SrCoO2.5 to HSrCoO2.5, H1.5SrCoO2.5, and H2SrCoO2.5 through formation of an intermediate phase of H1.25SrCoO2.5. H1.5SrCoO2.5 was colorless transparent and showed weak ferromagnetism. The present results indicate that the CAN film can be used as the solid electrolyte for the protonation treatment of TMOs. This work has been published in ACS Appl. Electron. Mater. 3, 3296-3300 (2021). Further, I created a solid-state thermal transistor using SrCoOx and YSZ and submitted a patent.

已经提出了几种基于SRCOOX的电化学设备，但是尚未在室温下从SRCOO2.5到HXSRCOO2.5（X = 1、1.5和2）的固态质子化，迄今尚未证明由于缺乏适当的固体电解质。我证明了使用中孔无形的12CAO ・7Al2O3（CAN）膜作为固体电解质，证明了SRCOO2.5的固态电化学质子化。结晶相通过形成H1.25SRCOO2.5的中间相，从SRCOO2.5转变为HSRCOO2.5，H1.5SRCOO2.5和H2SRCOO2.5。 H1.5SrCOO2.5是无色透明的，表现出弱的铁磁作用。目前的结果表明，可以将CAN膜用作TMO质子化处理的固体电解质。这项工作已发表在ACS Appl中。电子。母校。 3，3296-3300（2021）。此外，我使用SRCOOX和YSZ创建了一个固态热晶体管，并提交了一项专利。
