•Novel SVO nanomaterials for photocatalytic degradation BPA under visible light irradiation.•Ag/AgVO3 was visible-light-sensitive photocatalyst.•Ag/AgVO3 was effective and stable after using 8 cycles.•Hydroxyl radicals played a key role in the photocatalytic degradation reaction.
A novel composite nanomaterial of Ag/AgVO3 was prepared and the photocatalytic activity for the degradation of bisphenol A was investigated under visible light irradiation. Experimental results showed that Ag/AgVO3 exhibited higher photocatalytic activity than bare β-AgVO3 under visible light irradiation. The degradation efficiency of BPA by Ag/AgVO3 could reach 100% within 150 min. The obvious enhancement of photocatalytic activity by Ag nanoparticles could be attributed to the synergetic effects between noble metal and semiconductor. Furthermore, hydroxyl radicals (OH) played a key role in the photocatalytic reaction and a possible mechanism of the synergistic system was proposed.
