Synthesis of Hollow BiOCl-Decorated Bimetallic MOF(Bi/In)/Ti₃C₂T_x MXene for the Photodegradation of Rhodamine B Leila Ghaedrahmati (21532014) Mohammad Jafarzadeh (18414265) Biochemistry Space Science Physiology Pharmacology Biotechnology Evolutionary Biology Chemical Sciences not elsewhere classified Ecology within 80 min various proportions via structural analyses revealed four reuse cycles exhibited distinct morphologies demonstrated high performance carrier recombination compared 100 w led light photocatalytic efficiency sub >< italic 3 </ sub 2 </ sub decorated bimetallic mof rhb degradation efficiency degradation efficiency rhb degradation light irradiation rhb ). varying amounts suppressed charge solvothermal process rhodamine b retaining 87 primary components polyhedral particles organic frameworks monometallic counterparts hollow microspheres hollow biocl biocl formation 6 ev 10 wt Hollow microspherical bimetallic metal-organic frameworks (MOFs) were formed in situ in the presence of bismuth (Bi³⁺) and indium (In³⁺) cations, which serve as the primary components of the MOF secondary building units. In contrast, the monometallic counterparts, Bi-MOF and In-MOF, exhibited distinct morphologies: polyhedral particles and microrods, respectively. Morphological and structural analyses revealed that the hollow microspheres are composed of bismuth oxychloride (BiOCl)-like nanosheets, with the InCl₃ precursor supplying chloride ions necessary for BiOCl formation. Three-dimensional Bi/In-MOF was hybridized with two-dimensional Ti₃C₂ MXene in various proportions via a solvothermal process to produce Bi/In-MOF/Ti₃C₂ composites, which demonstrated high performance in the photodegradation of rhodamine B (RhB). Incorporation of 10 wt % Ti₃C₂ and varying amounts of Bi/In-MOFs resulted in a narrowed band gap (∼2.6 eV) and suppressed charge-carrier recombination compared to the bimetallic MOF alone (∼3.18 eV), thereby enhancing visible-light photocatalytic efficiency. The Bi/In-MOF­(20 wt % In)/Ti₃C₂(10 wt %) composite achieved a 95% RhB degradation efficiency under visible-light irradiation (100 W LED) within 80 min. Scavenger experiments identified superoxide radicals (O₂^•–) and holes (h⁺) as the dominant reactive species responsible for RhB degradation. The photocatalyst also demonstrated excellent structural stability, retaining 87% degradation efficiency after four reuse cycles. 2026-09-29T00:00:00Z Text Journal contribution 10.1021/acs.langmuir.6c04022.s001 https://figshare.com/articles/journal_contribution/Synthesis_of_Hollow_BiOCl-Decorated_Bimetallic_MOF_Bi_In_Ti_sub_3_sub_C_sub_2_sub_T_sub_x_sub_MXene_for_the_Photodegradation_of_Rhodamine_B/34024571 CC BY-NC 4.0
