This study investigates the energy characteristics of the adsorption layer formed on the surface of ZrO₂+3mol% Y₂O₃ nanopowder system under varying humidity conditions by thermogravimetry, electron microscopy, and nuclear magnetic resonance (NMR) spin-echo techniques. The spin–spin and spin–lattice relaxation times were determined at different relative ambient humidity. Our findings indicate slow relaxation of water molecules within the pore spaces of the samples, with a characteristic time parameter of 1.18 × 10^–7 s. Furthermore, a nonlinear relationship between desorption activation energy and humidity content was observed in the system. These results suggest the potential applicability of the investigated nano powder system as an adsorption device for energy storage purposes.
