Enhanced visible-light photocatalytic activity and stability over g-C3N4/Ag2CO3 composites
Source abstract
Abstract
A facile direct growth method was developed for the fabrication of Ag2CO3 nanoparticles on the surface of g-C3N4 at room temperature. The as-prepared g-C3N4/Ag2CO3 composites were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, transmission electron microscopy with energy dispersion X-ray spectroscopy, UV–vis diffuse reflectance spectroscopy, and photoluminescence spectroscopy. The photocatalytic activities were evaluated by degrading Rhodamine B dye. The results indicated that Ag2CO3 nanoparticles with the size of 5–10 nm were finely distributed on the surface of g-C3N4 sheet, leading to the enhancement of the photocatalytic activity. And when the mass ratio of g-C3N4 to Ag2CO3 was 1:4, the as-prepared composites exhibited the optimum photocatalytic activity, which was approximately 8 and 3 times higher than pure g-C3N4 and Ag2CO3, respectively. The enhanced photocatalytic performance could be attributed to the synergetic effects between g-C3N4 and Ag2CO3, including the smaller particle size of Ag2CO3 and high charge separation efficiency of the photogenerated electron–hole pair. More attractively, the stability of Ag2CO3 was improved due to its highly dispersion on g-C3N4 sheet. In addition, based on the experimental results, the Z-scheme mechanism for the photodegradation over g-C3N4/Ag2CO3 composites was proposed.
