Figure 4. (A) PEC water splitting of GaAs/CNT@MoS2-based photoelectrodes upon illumination; (B) LSV curves of GaAs, GaAs/MoS2 and GaAs/CNT@MoS2 photoelectrodes; (C) LSV curves of GaAs/MoS2 photoelectrodes with different MoS2 thickness. GaAs: Gallium arsenide; CNT: carbon nanotube; PEC: photoelectrochemical; LSV: linear sweep voltammetry; OCP: open-circuit potential; RHE: reversible hydrogen electrode.
