Growth of ZIF-67 on a Nickel Foam As a Three-dimensional Heterogeneous Catalyst for Peroxymonosulfate Activation
Overview
Affiliations
Advanced oxidation processes based on sulfate radicals have been widely used to eliminate contaminants. In this study, an efficient cobalt-based three-dimensional heterogeneous catalyst was fabricated through growth of ZIF-67 on nickel foam (NF/ZIF-67). The factors influencing NF/ZIF-67-activated peroxymonosulfate (PMS) were investigated. Enhanced RhB degradation was observed using NF/ZIF-67-activated PMS under neutral conditions and high temperatures. Sulfate radicals were the dominant active species for the oxidative decolorization of RhB with NF/ZIF-67-activated PMS. NF/ZIF-67 was easily separated from the solution, and it also retained high catalytic stability. This study provides a rapid and mild method for the fabrication of promising three-dimensional heterogeneous catalysts for PMS activation and wastewater treatment.
