Abstract
Development and application of multilayer semiconductor catalytic nanostructures based on transition metal chalcogenides with a given energy band structure is a promising direction in the hydrogen industry. Electric fields in the contact region of heterojunctions promote separation and accelerated transfer of nonequilibrium light-induced carriers in the volume of photoactive material of nanocatalysts. The paper studies the nanostructure and photocatalytic properties of two-stage MoS2/WS2/WSe2 heterostructures obtained by pulsed laser deposition. A significant increase in the photocurrent in the heterostructure was achieved compared to photocathodes based on individual films included in the heterostructure. The use of highly informative analysis methods (high-resolution transmission electron microscopy, Raman spectroscopy), as well as quantum-chemical calculations using the density functional theory method, allowed us to identify factors that can have an important effect on the functional characteristics of the created heterostructure.
