In the present study, we report about results of obtaining nanocomposite materials based on various types of nanoporous alumina membranes (NAM). The NAM were fabricated by two ways: (I) — using the technique of thinning the barrier layer of porous anodic alumina; (2) — by two-layer galvanostatic electrochemical anodization of aluminium samples. Using atomic force microscopy, it was found that a method of thermal decomposition of K2MnO4 leads to the formation of nanoparticles γ-MnO2 with size ~ 20 nm on the surface and in the pores of NAM, and the use of the method of photochemical synthesis of Ag nanoparticles with a size of ~ 30 nm.
