In this study, multiwalled carbon nanotubes (MWCNTs) were synthesized directly on the surface of a cylindrical stainless steel anode in this type of reactor to improve its decomposition performance. The surface area of the anode including the synthesized MWCNTs became approximately 332 times larger than that of the bare stainless steel anode. This increase in surface area enhanced the rate at which the phenol concentration decreased, although the degradation rate of total organic carbon (TOC) did not increase. When cobalt nanoparticles were loaded onto these MWCNTs, the TOC degradation rate improved significantly. The synthesis of MWCNTs on the anode surface was necessary to realize this enhancement. This study discusses the mechanisms of these enhancement effects.
