This study investigates a novel AOPs system that integrates the metal-organic framework MIL-88B(Fe) with sodium perborate (SPB) under visible light for the degradation of methylene blue (MB). The choice of SPB over traditional oxidants is motivated by its solid stability, ease of transport, and environmental friendliness. The coupling of MIL-88B(Fe) with SPB creates a remarkable synergy: MIL-88B(Fe) acts as an activator for SPB, while the presence of SPB inhibiting the recombination of electrons and holes and facilitates the crucial photo-reduction of Fe(III) to Fe(II) in MIL-88B(Fe), establishing a sustainable catalytic cycle. This synergistic effect resulted in a dramatic enhancement in MB degradation efficiency, achieving 95% within 30 minutes, higher than that of the MIL-88B(Fe)/vis system, exhibited enhancement of degradation efficiency (SI = 6.07). Radical quenching experiments and EPR measurements identified ·OH and ·O 2 − as the primary reactive oxygen species. This MIL-88B(Fe)/SPB/vis system showcases a promising, sustainable strategy for wastewater treatment by effectively combining a stable heterogeneous catalyst with a green oxidant.

oxidation processes (AOPs). This study investigates a novel AOPs system that integrates the metal-organic framework MIL-88B(Fe) with sodium perborate (SPB) under visible light for the degradation of methylene blue (MB). The choice of SPB over traditional oxidants is motivated by its solid stability, ease of transport, and environmental friendliness. The coupling of MIL-88B(Fe) with SPB creates a remarkable synergy: MIL-88B(Fe) acts as an activator for SPB, while the presence of SPB inhibiting the recombination of electrons and holes and facilitates the crucial photo-reduction of Fe(III) to Fe(II) in MIL-88B(Fe), establishing a sustainable catalytic cycle. This synergistic effect resulted in a dramatic enhancement in MB degradation efficiency, achieving 95% within 30 minutes, higher than that of the MIL-88B(Fe)/vis system, exhibited enhancement of degradation efficiency (SI\u0026thinsp;=\u0026thinsp;6.07).

This MIL-88B(Fe)/SPB/vis system showcases a promising, sustainable strategy for wastewater treatment by effectively combining a stable heterogeneous catalyst with a green oxidant.\u003c/p\u003e","manuscriptTitle":"Synergistic Catalysis: Sodium Perborate-Mediated Advanced Oxidation Processes Coupled with MIL-88B(Fe) for Photocatalytic Degradation of Methylene Blue","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-10-29 23:34:07","doi":"10.21203/rs.3.rs-7727918/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2025-11-01T12:20:57+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-10-31T21:51:44+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-10-23T09:04:09+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"62090936058862776059518309204522309816","date":"2025-10-16T08:50:17+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"2993133641419913480056263438570200936","date":"2025-10-16T07:16:58+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-10-16T07:08:59+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-10-04T20:30:33+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2025-10-04T20:29:40+00:00","index":"","fulltext":""},{"type":"submitted","content":"Research on Chemical Intermediates","date":"2025-09-27T10:55:24+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"research-on-chemical-intermediates","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"rint","sideBox":"Learn more about [Research on Chemical Intermediates](http://link.springer.com/journal/11164)","snPcode":"11164","submissionUrl":"https://submission.nature.com/new-submission/11164/3","title":"Research on Chemical Intermediates","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"em","reportingPortfolio":"Springer Hybrid","inReviewEnabled":true,"inReviewRevisionsEnabled":false}}],"origin":"","ownerIdentity":"707416ce-9b21-493e-8e72-dff9e78f54d0","owner":[],"postedDate":"October 29th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"published-in-journal","subjectAreas":[],"tags":[],"updatedAt":"2025-12-15T16:09:37+00:00","versionOfRecord":{"articleIdentity":"rs-7727918","link":"https://doi.org/10.1007/s11164-025-05848-2","journal":{"identity":"research-on-chemical-intermediates","isVorOnly":false,"title":"Research on Chemical Intermediates"},"publishedOn":"2025-12-11 15:59:40","publishedOnDateReadable":"December 11th, 2025"},"versionCreatedAt":"2025-10-29 23:34:07","video":"","vorDoi":"10.1007/s11164-025-05848-2","vorDoiUrl":"https://doi.org/10.1007/s11164-025-05848-2","workflowStages":[]},"version":"v1","identity":"rs-7727918","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7727918","identity":"rs-7727918","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
