外文摘要：Effective removal of organic pollutions and efficient conversion of carbon dioxide (CO2) under illumination still pose challenges at present. Herein, carbon nitride (g-C3N4) nanosheets were successfully fabricated via high temperature calcination with melamine as raw material. As a typical p-type semiconductor, cobalt oxide (CoO) particles with the sphere-like morphology were embedded in g-C3N4 nanosheets to construct the g-C3N4/CoO composites via impregnation and thermal polymerization. High dispersion of CoO particles into g-C3N4 matrix effectively prohibits their agglomeration, which can gain larger specific surface area, greatly surpassing that of their components. Furthermore, the well coupled interface between components was successfully constructed to improve charge separation and transfer via p-n junction. The above benefits endow g-C3N4/CoO composites with the excellent photocatalytic activity of methyl orange (MO) degradation and CO2 reduction, remarkably superior to g-C3N4 and CoO. The successful preparation of g-C3N4/CoO p-n heterojunctions may be a general and beneficial approach to constructing the visible-light-responsive photocatalytic materials.
