Abstract
A method for regulating a phase transformation of a hydrogen-containing transition metal oxide comprises steps of: providing a hydrogen-containing transition metal oxide having a structural formula of ABOH, wherein the hydrogen-containing transition metal oxide is in form of a first phase, A is one or more of alkaline earth metal elements and rare-earth metal elements, B is one or more of transition metal elements, x is a numeric value in a range of 1 to 3, and y is a numeric value in a range of 0 to 2.5; soaking the hydrogen-containing transition metal oxide with a first ionic liquid capable of providing hydrogen ions and oxygen ions; and applying a gating voltage to the hydrogen-containing transition metal oxide with the first ionic liquid as a gate to regulate the phase transformation of the hydrogen-containing transition metal oxide.
