Abstract

In this paper, we report fabrication and photoelectrochemical properties of nanocomposites MoS₂ -TiO₂ prepared by high energy ball milling. Scanning electron microscope with energy dispersive x-ray spectroscopy (SEM-EDX) has been applied for analyzing morphology and elements distribution of the nanocomposites. The two immiscible solids (1:1 MoS₂/TiO₂) shows uniform dispersion at nano-scale as well as retain a well crystalline state for extending the ball milling time till 32hours. Photoelectrochemical characterization has been performed through a three-electrode electrochemical quartz reactor under simulated solar light and UV light radiation. An obvious photoelectrical effect has been observed in the range of -60mV - 100mV potential. The nanocomposites might be a suitable photoelectrode material for solar energy conversion such as water splitting.
