Fabrication and photocatalytic property of MoOx nano-particle films from Mo target by laser ablation at ambient conditions
Source abstract
Abstract
Abstract MoOx nanoparticle (NP) films were fabricated through laser ablation from molybdenum target at ambient conditions. The structure, optical properties and photocatalytic performance of the MoOx NP films were characterized under different laser irradiation times. XRD patterns indicate that laser irradiation can accelerate the oxidation and improve the orientation of MoOx NP films. The samples after irradiation show broad absorption peaks from the visible to infrared regions with significant improvement photocatalytic performance in hydrogen generation compared with that of the as-ablated sample with 1.33 times. The oxygen vacancies generated in the case of laser irradiation was demonstrated to dominate the localized surface plasmon resonance (LSPR) and photocatalytic performance by varying the laser irradiation times.
