▎ 摘　　要

This work presented non-toxic green synthesis of SrCO3 particles prepared using fruit extracts and graphene oxide (GO) as agents. Strontium nitrate was used as a source of the strontium ions, while carbon sources were derived from sodium bicarbonate and urea, respectively. With the co-precipitation and hydrothermal methods, the mineralization of SrCO3 was induced by above agents. The resultant crystals were characterized by scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, and X-ray powder diffractometry (XRD). The photocatalytical activity of the obtained SrCO3 particles was studied. The surface morphology of the particles showed that, depending on the templates used, the samples vary in size and shape distribution were due to the interaction between mineralization methods and templates. The obtained results also presented that SrCO3/GO hybrids had a higher photocatalytic degradation capacity of methylene blue compared to SrCO3 particles.
