Nanocompositemembranes have been actively developed in the last decade. The involvement
of nanostructures can improve the permeability, selectivity, and anti-fouling properties of amembrane for
improved filtration processes. In this work, we propose a novel type of ion-selective Glass/Au composite
membrane based on porous glass (PG), which combines the advantages of porous media and promising
selective properties. The latter are achieved by depositing gold nanoparticles into the membrane pores
by the laser-induced liquid phase chemical deposition technique. Inside the pores, gold nanoparticles
with an average diameter 25 nm were formed, which was confirmed by optical and microscopic studies.
To study the transport and selective properties of the PG/Au composite membrane, the potentiometric
method was applied. The uniform potential model was used to determine the surface charge from the
experimental data. It was found that the formation of gold nanoparticles inside membrane pores leads
to an increase in the surface charge from 2.75 mC/m2 to 5.42 mC/m2. The methods proposed in
this work allow the creation of a whole family of composite materials based on porous glasses. In this
case, conceptually, the synthesis of these materials will di er only in the selection of initial precursors.
