Abstract

Abstract:

Hybrid hydrogen evolution catalyst of RGO-MoS_x was prepared by an in situ photoreduction method, in which GO (graphene oxide) and (NH₄)₂MoS₄ (ammonium thiomolybdate) was employed as the precursor, Eosin Y (EY) as the photosensitizer, and TEOA (triethanolamine) as the sacrificial electron donor. 2.10 times' enhancement in photocatalytic hydrogen evolution was observed due to the introduction of GO. Raman spectra, FTIR spectra, TEM, SEM, and XPS were used to characterize the composition, structure and morphology of RGO-MoS_x catalyst.

Key words: RGO-MoS_x, in situ photoreduction, photocatalytic hydrogen evolution
