Abstract:
The development of photoelectrochemical (PEC) water-splitting systems offers a viable technology for sustainable hydrogen production, addressing global energy needs. Herein, a Co-doped MoS2@TiO2 self-supported nanoarray photoelectrode is developed. It exhibits a high photoelectrochemical hydrogen evolution rate of 41.67 µmol h-1 cm-2, which is 7.8 and 1.47 times higher than those of a pristine TiO2 nanoarray and a MoS2@TiO2 nanoarray. The synergistic enhancement in hydrogen evolution is attributed to the extended visible-light absorption, enhanced charge separation, and optimized hydrogen adsorption free energy.
