Abstract
Metal oxide integrated metal organic framework (MOF) composites enhance the synergistic properties of pristine organic framework materials. A series of Bi2O3 modified iron succinic acid organic frameworks (Bi2O3@Fe-SA) was synthesized with various Fe: Bi molar ratios by hydrothermal approach. The synthesized materials were primarily characterized for crystal structures, morphology and chemical constitution, functional groups, band energies, surface charge, surface area, and charge carriers’ recombination with the different instrumental techniques like XRD, FESEM and EDX, FTIR, UVDRS, Zeta potential, BET, and PL analysis. Synthesized materials were examined for the photocatalytic degradation of an organic pollutant namely Rhodamine B (RhB) dye. Among all the synthesized materials, Bi2O3@Fe-SA (1) exhibited highest degradation efficiency of 80.00 % in 120 min under visible irradiation. The photodegradation kinetics and reactive species participating in the degradation reaction were also inspected. The degradation mechanism was proposed that expressed the efficient charge injection on the connected interfaces and which are responsible for the enhanced photodegradation efficiency of the nanocomposite photocatalysts.
