Method for controlling and controlling phase transition of hydrogen-containing transition metal oxide

摘要

The method for controlling and controlling the phase transition of the hydrogen-containing transition metal oxide includes the following steps S100 to S300. In S100, a hydrogen-containing transition metal oxide having the structural formula ABOxHy is provided, wherein the hydrogen-containing transition metal oxide is in a first phase, and A is at least one of an alkaline earth metal element and a rare earth metal element. Yes, B is a transition metal element, the value range of x is 1-3, and the value range of y is 0-2.5. In S200, the hydrogen-containing transition metal oxide is immersed in a first ionic liquid, and the first ionic liquid can provide hydrogen ions and oxygen ions. In S300, the first ionic liquid is used as a gate, and a gate voltage is applied to the hydrogen-containing transition metal oxide to adjust and control the phase transition of the hydrogen-containing transition metal oxide.
