Abstract
"Fabrication of cost-effective and an efficient catalyst is a greatly crucial to satisfy the requirements of removal of
organic pollutants from the wastewater to ensure the green healthy environment yet remains vast challenge. In
this regard, simple strategy has been adopted to develop the hybrid structure by employing the ruthenium (Ru)
nanoparticles anchored on the metal-organic-framework (Ru@ZIF-8 and Ru@ZIF-67) interface and its overall
photocatalytic performance was explored. Experimental results demonstrate that Ru@ZIF-8 hybrid exhibited a
higher photocatalytic activity than that of the Ru@ZIF-67, ZIF-8 and ZIF-67 and the degradation efficiency of the
crystal violet (CV; 96 %) and rhodamine B (RhB; 97.9) could attain under visible irradiations for about 80 min. In
particular, the effects of CV dosage concentrations and various pH effects with the Ru@ZIF-8 hybrid were
explored in detail. Moreover, the optimized Ru@ZIF-8 hybrid did not reveal the considerable loss of the photocatalytic
activity after six cycles, revealing its long-term reusability and stability. The photocatalytic mechanism
was conducted through trapping-species-experiment, confirming that superoxide (•O-2) and electron (e-)
contributed significant role in the degradation of the CV with Ru@ZIF-8 hybrid. Thus, the current study offers a
new-strategy to design Ru@ZIF-8 as photocatalyst with higher photocatalytic performance for wastewater
treatment."
