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
Listed in ZivaHub
Hollow microspherical bimetallic metal-organic frameworks (MOFs) were formed in situ in the presence of bismuth (Bi<sup>3+</sup>) and indium (In<sup>3+</sup>) cations, which serve as the primary components of the MOF secondary building units.
Description
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 InCl<sub>3</sub> precursor supplying chloride ions necessary for BiOCl formation.
Three-dimensional Bi/In-MOF was hybridized with two-dimensional Ti<sub>3</sub>C<sub>2</sub> MXene in various proportions via a solvothermal process to produce Bi/In-MOF/Ti<sub>3</sub>C<sub>2</sub> composites, which demonstrated high performance in the photodegradation of rhodamine B (RhB). Incorporation of 10 wt % Ti<sub>3</sub>C<sub>2</sub> 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)/Ti<sub>3</sub>C<sub>2</sub>(10 wt %) composite achieved a 95% RhB degradation efficiency under visible-light irradiation (100 W LED) within 80 min. Scavenger experiments identified superoxide radicals (O<sub>2</sub><sup>•–</sup>) and holes (h<sup>+</sup>) as the dominant reactive species responsible for RhB degradation. The photocatalyst also demonstrated excellent structural stability, retaining 87% degradation efficiency after four reuse cycles.
