The photoluminescence and anti-thermal degradation properties of coated BAM were investigated under 254 and 147nm excitations. The optimum anti-thermal degradation properties are obtained......
), scanning electron microscopy (SEM), Fourier transformed infrared spectroscopy (FT-IR) and thermal gravimetric analysis and differential thermal analysis (DTA-TG). Subsequently, the photocatalytic performances of Bi2S3 microsphere were evaluated by photocatalytic degradation of methyl orange (MO) simulation solution under visible-light irradiation. The results show that, Bi2S3 microsphere could be used......
