Abstract

Platinum has been utilized as an excellent electrocatalyst with low overpotential for the hydrogen evolution reaction (HER) in water splitting, despite of its high cost. In this study, platinum particles were produced using pulsed laser technology as a HER catalyst for water splitting. The colloidal platinum particles were synthesized by nanosecond pulsed laser irradiation (PLI) without reducing agents, not traditional polyol processes including reducing agents. The crystal structure, shape and size of the synthesized platinum particles as a function of pulsed laser irradiation time were investigated by XRD and SEM analysis. Additionally, the electrochemical properties for the HER in water splitting of the irradiation time-dependent platinum electrocatalysts were studied with the analysis of overpotentials in linear sweep voltammetry and Tafel slope.
