Source abstract
Abstract
In this work, a desired Cu2O catalyst supported on graphitic carbon nitride and reduced graphene oxide hybrid (Cu2O/g-C3N4–rGO) with excellent catalytic performance in the reduction of 4-nitrophenol (4-NP) by NaBH4 has been fabricated. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), electrochemical impedance spectroscopy (EIS), N2 adsorption/desorption and Fourier-transform infrared (FTIR) techniques as well as catalytic test using the reduction of 4-NP by NaBH4 as probe reaction have been used to investigate the structure–properties relationship of the as-prepared Cu2O/g-C3N4–rGO composites. The results demonstrate that ultrafine Cu2O nanoparticles can be stably anchored on g-C3N4–rGO hybrid by tuning the initial ratio of rGO (reduced graphene oxide) to g-C3N4, where homogeneous dispersion of g-C3N4 on sheet-like rGO plays a very important role in confining the ultrafine Cu2O nanoparticles and excellent catalytic performance is noticed on Cu2O/g-C3N4–rGO composite for the reduction of 4-NP by NaBH4 with an activity parameter up to 6330 s-1g-1.
