Present photocatalysts for the synchronous cleanup of pharmaceuticals and heavy metals have several drawbacks, including inadequate reactive sites, inefficient electron–hole disassociation, insufficient oxidation reduction power. In this research, we sought to address these issues by using a facile solvothermal-photoreduction route develop an innovative plasmonic S-scheme heterojunction, Au/MIL-101(Fe)/BiOBr. The screened-out Au/MIL-101(Fe)/BiOBr (AMB-2) works in durable high-performance manner both Cr(VI) norfloxacin (NOR) eradication under visible light, manifesting up 53.3 2 times greater NOR abatement rates, respectively, than BiOBr. Remarkably, AMB-2's ability remove Cr(VI)-NOR co-existence system is appreciably better sole-Cr(VI) environment; synergy among Cr(VI), NOR, AMB-2 results utilization photo-induced carriers, yielding desirable capacity decontaminating synchronously. integration MOF-based heterojunctions effect contributes markedly reinforced photocatalytic increasing number active augmenting visible-light absorbance, boosting efficient disassociation redistribution powerful photo-carriers, elevating generation substances. We provide details mechanism, decomposition process, bio-toxicity intermediates. This synergistic strategy modifying with noble metal opens new horizons devising excellent photosystems environment purification.

Abstract Constructing S-scheme heterojunctions proves proficient in achieving the spatial separation of potent photogenerated charge carriers for their participation photoreactions. Nonetheless, restricted contact areas between two phases within heterostructures lead to inefficient interfacial transport, resulting low photocatalytic efficiency from a kinetic perspective. Here, In 2 O 3 /Nb 5 are fabricated through straightforward one-step electrospinning technique, enabling intimate and thereby fostering ultrafast electron transfer (<10 ps), as analyzed via femtosecond transient absorption spectroscopy. As result, powerful photo-electrons holes accumulate Nb conduction band valence band, respectively, exhibiting extended long lifetimes facilitating involvement subsequent Combined with efficient chemisorption activation stable CO on , hybrid nanofibers demonstrate improved performance conversion.
