Abstract

Metal tellurides are highly sought after for energy and spintronic applications much of which is owed to its catalytic and magnetic properties. Confining it into two-dimensions and improving the surface area enriches its catalytic activity and magnetic properties. Herein, we demonstrate the isolation of ultrathin two-dimensional sheets of manganese(II)telluride having an average thickness of ∼2 nm and flake size of ∼100 nm by means of liquid phase exfoliation presumably for the first time. Vanishing of exchange interactions in two-dimensions results in paramagnetic ordering in manganese(II)telluride sheets while its pristine form prefers antiferromagnetic order. The exfoliated two-dimensional sheets were used to sensitize titania nanotubes to broaden the absorption spectrum and utilize visible light for photoelectrochemical water splitting.
