Enhanced photocatalytic activity by synergic action of ZIF-8 and NiFe2O4 under visible light irradiation

ZIF-8 metal organic framework materials as a superb platform for the removal and photocatalytic degradation of organic pollutants: a review

“…Moreover, its magnetic property allowed the composite to be regenerated and reused for 4 cycles without loss of its properties such as degradation efficiency (90%). 124 Chandra and co-authors 125 reported the synthesis of a composite named ZIF-8/AgNPs for the photocatalytic degradation of MB. Due to its large specific surface area (1370.91 m 2 g −1 ) and unique synergistic characteristics, the sample prepared with a 300 μL suspension of AgNPs displayed outstanding photocatalytic efficiency towards methylene blue with a degradation rate of 97% at pH ≥ 7.…”

“…Recently, Faraji et al 124 exploited the magnetic properties of NiFe 2 O 4 to form a ZIF-8/NiFe 2 O 4 -based composite, which could be easily separated from the reaction medium. The prepared photocatalyst was evaluated for the photocatalytic decomposition of methylene blue.…”

Synergistic effect of modified pore and heterojunction of MOF-derived α-Fe2O3/ZnO for superior photocatalytic degradation of methylene blue

“…8 However, there are some drawbacks of ZnO such as fast carrier recombination rate, low quantum yield efficiency, and lower separation charge transfer. 9,10 Moreover, morphology, surface area and pore size distribution are still the main obstacles to ZnO as a photocatalyst. Comparing the performance of semiconductors with bulky and porous structures, it has been reported in previous studies that bulky structures cause volume recombination that will reduce the performance or inactivity of the semiconductor.…”

Application of response surface methodology for methylene blue removal using an innovative ZIF-8/NiFe2O4/ halogen lamp system

“…Thus, this expectation led us to synthesize magnetic ZIF-8/NiFe 2 O 4 nanocomposites by a simple hydrothermal method for the rst time [34]. The synthesized nanocomposite was applied for photocatalytic degradation of methylene blue (MB) dye.…”
