CO2-Assisted Fabrication of Two-dimensional Amorphous Transition Metal Oxides
This Frontier presents the recent developments and applications of two-dimensional (2D) amorphous transition metal oxides (TMOs) obtained by supercritial CO2. CO2 molecules can affect the crystal transformation of the layered materials and allow diffusive atomic disordering during the exfoliation process. Owing to introduction of amorphous structure, the strong localization tail states in gap of transition metal oxides can effectively promote chemical reactions. We also discuss the further challenges to be overcome for this class of supercritical CO2 and 2D amorphous materials in the future.
