Abstract:
It has been found that the pulsed laser deposition of a thin tungsten selenide film, followed by thermal treatment at 550$^\circ$C in an Ar + O$_2$ mixture of gases, results in the formation of a hybrid structure that is made up of ultrathin WSe$_2$ and WO$_{3-y}$ platelets. The structural and size characteristics of the nanoplatelets deposited on microcrystalline graphite provide the effective hydrogen evolution reaction in a 0.5 M H2SO4 solution, with the cathode current made about seven times higher at a potential of–100 mV and the slope of the Tafel characteristic reduced from 340 to 90 mV/dec.
