Abstract
The efficiency of photoactivated hydrogen evolution in an acidic solution on p-Si cathode with thin film of amorphous molybdenum sulfide catalyst was investigated. A significant influence of the method of forming the catalyst film on the photocathode quality was established. The greatest photocurrent value in the case of applying a catalytic film by the traditional method of pulsed laser deposition from MoS2 target was found. Varying the conditions of the reaction pulsed laser deposition from the Mo target in hydrogen sulfide didn’t allow the high hydrogen production to be realized. Possible reasons for the difference in the functional characteristics of the created photocathodes was identified.
