© 2020, Pleiades Publishing, Ltd.Abstract: MoS2 nanofilms were created by thermochemical processing (sulfurization) of thin-film Мо and МоОу precursors in S vapor. The precursor films were created by pulsed laser deposition. The obtained molybdenum disulfide films consisted of 2H-MoS2 nanocrystals with laminar packing of basal planes oriented perpendicular to the film surface. The increase in the sulfurization temperature from 500°C to 800°C provided better quality of local packing and, as a consequence, reduction of electric resistance, higher concentration of carriers (electrons) and their mobility. The application of metal oxide precursor МоОу resulted in higher efficiency of synthesis of high quality MoS2 nanofilms. The efficiency of activation of the electrochemical processes of hydrogen production in an acidic solution was lower with crystalline MoS2 nanofilms than with amorphous MoSx films. Nanocrystalline MoS2 films, however, manifested improved photo- and electrocatalytic characteristics in activation of reactions of hydrogen and oxygen evolution in an alkaline solution.
