Abstract

A liquid-based organic solvent-assisted grinding and sonication method was adopted for the formation of two dimensional (2D) moderately hydrated α-MoO nanoflake suspensions, with a flake thickness in the order of ∼1.4 nm. This thickness is equal to the largest unit cell parameter of α-MoO . The implemented method had the advantage of simplicity and resulted in a high yield of nanoflakes that were highly crystalline across the planes. This method can be incorporated into 2D semiconducting material-enabled devices. Conductometric transduction templates based on drop-casted thin films of these 2D α-MoO flakes were developed for H gas sensing. The sensors showed large responses to H gas with..
