Heterostructured Bi₂S₃@NH₂-MIL-125(Ti) nanocomposite as a bifunctional photocatalyst for Cr(vi) reduction and rhodamine B degradation under visible light.

ABSTRACT: A series of bismuth sulfide (Bi₂S₃) nanorods and amine-functionalized Ti-based metal-organic framework heterojunctions [denoted by Bi₂S₃@NH₂-MIL-125(Ti)] were constructed and explored as bifunctional photocatalysts for Cr(vi) reduction and rhodamine B (RhB) degradation under visible light illumination. Compared with the individual NH₂-MIL-125(Ti) and Bi₂S₃, the as-synthesized Bi₂S₃@NH₂-MIL-125(Ti) photocatalyst exhibited an enhanced photocatalytic activity toward Cr(vi) and RhB owning to the synergetic effect between Bi₂S₃ and NH₂-MIL-125(Ti). Moreover, the Bi₂S₃@NH₂-MIL-125(Ti) heterojunctions showed incr
