Pulsed Laser Phosphorus Doping and Nanocomposite Catalysts Deposition in Forming a-MoS_x/NP-Mo//n⁺p-Si Photocathodes for Efficient Solar Hydrogen Production.

ABSTRACT: Pulsed laser deposition of nanostructured molybdenum sulfide films creates specific nonequilibrium growth conditions, which improve the electrocatalytic properties of the films in a hydrogen evolution reaction (HER). The enhanced catalytic performance of the amorphous a-MoS_x (2 ≤ x ≤ 3) matrix is due to the synergistic effect of the Mo nanoparticles (Mo-NP) formed during the laser ablation of a MoS₂ target. This work looks at the possibility of employing a-MoS_x/NP-Mo films (4 and 20 nm thickness) to produce hydrogen by photo-stimulated HER using a p-Si cathode. A simple technique of pulsed laser p-Si doping with phosphorus was used to form an n⁺p-junction. Investigations of the energy band arrangement at the interface between
