Cobalt/graphene carbon beads clear antibiotic pollutant from water without metal leaching
Researchers at Hebei University of Technology, Nankai University, and the Oil & Gas Technology Research Institute of Huabei Oilfield Company have developed a millimeter-scale, magnetically recoverable carbon bead catalyst that achieves complete removal of the antibiotic sulfamethoxazole (SMX) from water within 20 minutes, while largely avoiding the metal leaching that has limited earlier cobalt-based catalysts for this kind of water treatment.
Sulfamethoxazole is a widely used antibiotic that has been accumulating in water systems, and cobalt-based catalysts are among the most effective materials for breaking it down via peroxymonosulfate (PMS) activation, but conventional powdered cobalt catalysts tend to leach metal into the water over time, degrading their performance and creating a secondary pollution problem of their own. To get around this, the team built millimeter-sized beads (named CoNC@cPAN/rGO-800) by combining a cobalt-based metal-organic framework precursor (ZIF-67) with polyacrylonitrile (PAN) and graphene oxide, then calcining the mixture into a porous carbon structure with cobalt species locked inside. The graphene oxide is reduced to rGO during this process and lowers the material’s electronic impedance and helps disperse the cobalt more evenly through the carbon framework. The primary catalytic site is the embedded cobalt nanoparticles and cobalt oxide.
