Can nanosheets reduce the interfacial surface area of gas-liquid mass transfer at relatively high concentrations?? and what about nanospheres?

The lifetime of water mist droplets, depending on external conditions, can increase by several hundred times if 0.04-0.15% of high molecular weight alcohol is added to the water. As the droplets evaporate, the concentration of alcohol on their surfaces increases very strongly due to the large difference between the rate of diffusion of water molecules from the surface of the drop into the external environment and the rate of diffusion of alcohol from the surface into the drop, resulting in the formation of a monolayer of alcohol. Projects have been proposed to reduce the evaporation of water from Lake Sevan by using monolayers of poorly soluble amphiphilic molecules.
The convex surface of the droplets is distinguished by the fact that the saturated pressure above it will be greater than above a flat surface, which facilitates evaporation from a convex surface compared to evaporation from a flat liquid surface. Other properties of colloidal systems can be viewed in

I think it completely depends on porosity of the nanomaterial and gas and surface interactions. So if you use porous nanosheet with modified surface it may works for your purpose.
