Photocatalytic degradation of rhodamine-B by visible light assisted peroxymonosulfate activation using the Z-scheme MIL-100(Fe)/Bi₂S₃ composite: a combined experimental and theoretical approach

Abstract

The photocatalytic efficiency of binary MIL-100(Fe)/Bi2S3 (MIL-BS) composite was utilized towards visible light assisted peroxymonosulfate (PMS) activation and degradation of Rhodamine-B (RhB) dye. The binary catalyst, with 10wt% Bi2S3 (MIL-BS(10)),...

Unveiling the mechanism of visible light-assisted peroxymonosulfate activation and carbamazepine degradation using NH2-MIL-125(Ti)@MIL-53(Fe/Co) heterojunction photocatalyst

“…66,67 The weak ROS scavenging tendency and slight dimerization of SO 4 ˙− radicals may lead to minor inhibition (eqn (S16)-(S22) †). 34,68 Although SO 4 2− ions cannot react with SO 4 ˙− radicals, they can react with ˙OH to generate SO 4 ˙− radicals. Alternatively, the minor inhibition towards CBZ degradation was also due to the decrease in the reduction potential of the SO 4 ˙− radicals in the presence of SO 4 2− ions.…”
