Abstract

We have designed a nanocomposite of silver nanoparticle and carbon nanospheres (AgNPs/CNSs) as a catalyst for the rapid degradation of organic pollutants. The photocatalytic performance of the nanocomposite was examined by evaluating the degradation of methylene blue (MB) under UV light irradiation. The degradation percentages of the pollutant dye (MB) are: AgNPs/CNSs (~90.82%), AgNPs (~80.18%) under UV irradiation for 60 min. Furthermore, stability performance is studied by recycling the AgNPs/CNSs composite. It is found that the photocatalytic activity of AgNPs/CNSs composite is slightly decreased even after five cycles. In a nutshell, this novel composite AgNPs/CNSs exhibit time-dependent remarkable catalytic activity under UV light irradiation.
