摘要In this work, PbS quantum dots were for the first time directly deposited on graphene nanowalls substrate by electrochemical atomic layer epitaxy (ECALE) deposition method. The morphology, composition and 3D structure of PbS/graphene were characterized by field emission scanning electron microscope (FE-SEM), X-ray diffraction (XRD) and Raman spectrum, respectively. The sensitized three-dimensional graphene electrode with PbS quantum dots had great improvement in the performance of photo-electrochemical (PEC), with photocurrent almost four times that of pure graphene film, which presents its great application potential in the fields of photodetector or solar cell.
