Amine-Functionalized Bimetallic Ce/Zr-based MOF as an Effective Adsorptive Photocatalyst for the Removal of Persistent Organic Dye
A Ce/Zr-based bimetallic metal-organic framework functionalized with an amine group (Ce-UiO-66-NH 2 ) has been prepared via a solvothermal method to effectively remove dye contaminants from wastewater. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), and the Brunner-Emmet-...

| description | A Ce/Zr-based bimetallic metal-organic framework functionalized with an amine group (Ce-UiO-66-NH
2
) has been prepared via a solvothermal method to effectively remove dye contaminants from wastewater. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), and the Brunner-Emmet-Teller (BET) analysis all demonstrate that Ce-UiO-66-NH
2
has a significantly higher surface area and porous structure. Ce-UiO-66-NH
2
exhibited considerably superior adsorption and photocatalytic efficiency in the removal of the persistent Rhodamine B (RhB) dye in water compared to unfunctionalized UiO-66 and functionalized UiO-66-NH
2
. The enhanced adsorptive photocatalytic performance of Ce-UiO-66-NH
2
may be attributed primarily to its porosity and larger surface area (321.902 m
2
/g). Moreover, the redox system facilitated the process of adsorption by serving as an adsorption site via electrostatic interaction and the complex interaction between Ce
3+
and RhB. The Freundlich adsorption and pseudo-second-order kinetic models accurately described the adsorption of RhB on Ce-UiO66-NH
2
, indicating that the adsorption process was primarily dominated by multilayer cooperative adsorption. The present research contributes to the comprehension of the effects of amine functionalization and mixed valences of metals on the adsorption properties of MOFs.
