Precise manipulation of gas adsorption and desorption in the BeS monolayer can be carried out by means of an electric field, such as a gate voltage in a 2D material transistor.

We proposed a novel scheme for achieving enhanced photocatalytic activity in two-dimensional nanomaterials. Traditionally, substitution functionalization and Van der Waals heterostructures have been popular methods for enhancing photocatalytic activity. We...
