Treatment of industrial wastewater, including textile wastewater, using UV irradiation in combination with oxidants or catalysts (TiO₂). In this study, TiO₂-SnO₂ nanocomposites of different ratios will be prepared and characterized, and their use in the photocatalytic degradation of Acid Red 37 dye in aqueous solution under UV irradiation as a model pollutant will be examined. TiO₂-SnO₂ nanocomposites were characterized using XRD, TEM, EDAX, FTIR, Eg, and XPS using a batch photoreactor. The photocatalytic degradation was investigated utilizing several advanced oxidation processes with SnO₂ contents (0–15 wt %). Adding inorganic antioxidants (H₂O₂, Na₂S₂O₈, and NaIO₄) with a UV/TiO₂-SnO₂ ratio (90:10) for high efficiency. Then the effect of pH, dye concentrations, and different loadings (g/L) of nanocomposite on the photocatalytic activity of the SnO₂-TiO₂ (90:10) nanocomposite was studied.

Treatment of industrial wastewater, including textile wastewater, using UV irradiation in combination with oxidants or catalysts (TiO₂). In this study, TiO₂-SnO₂ nanocomposites of different ratios will be prepared and characterized, and their use in the photocatalytic degradation of Acid Red 37 dye in aqueous solution under UV irradiation as a model pollutant will be examined. TiO₂-SnO₂ nanocomposites were characterized using XRD, TEM, EDAX, FTIR, Eg, and XPS using a batch photoreactor. The photocatalytic degradation was investigated utilizing several advanced oxidation processes with SnO₂ contents (0\u0026ndash;15 wt %). Adding inorganic antioxidants (H₂O₂, Na₂S₂O₈, and NaIO₄) with a UV/TiO₂-SnO₂ ratio (90:10) for high efficiency. Then the effect of pH, dye concentrations, and different loadings (g/L) of nanocomposite on the photocatalytic activity of the SnO₂-TiO₂ (90:10) nanocomposite was studied.\u003c/p\u003e","manuscriptTitle":"A comprehensive study of the heterojunction effect of Sn on TiO₂ for UV irradiation via organic compounds and the effect of optical properties, pH, and catalyst loading on photodegradation efficiency.","msid":"","msnumber":"","nonDraftVersions":[{"code":2,"date":"2025-11-05 08:03:39","doi":"10.21203/rs.3.rs-6088607/v2","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}},{"code":1,"date":"2025-04-09 19:01:54","doi":"10.21203/rs.3.rs-6088607/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"1c774358-3751-446a-91d5-c29fbf44d811","owner":[],"postedDate":"November 5th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[{"id":57351126,"name":"Physical sciences/Chemistry"},{"id":57351127,"name":"Earth and environmental sciences/Environmental sciences"},{"id":57351128,"name":"Physical sciences/Materials science"},{"id":57351129,"name":"Physical sciences/Nanoscience and technology"}],"tags":[],"updatedAt":"2025-12-31T08:24:08+00:00","versionOfRecord":[],"versionCreatedAt":"2025-11-05 08:03:39","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v2","identity":"rs-6088607","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-6088607","identity":"rs-6088607","version":["v2"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
