Abstract

We have successfully obtained highly isolated Co2+ active sites on the surface of titanate nanotubes (TNTs) by a simple ion-exchange process. The as-prepared Co-TNTs were applied in heterogeneous catalysis to generate powerful radicals from peroxymonosulfate (PMS) for the removal of recalcitrant pollutant. Under the same conditions, Co-TNTs exhibited better degradation efficiency of Rhodamine B (RhB) than conventional CoFe2O4 and Co3O4. Some potential influential factors and recycling application were systematically investigated. We believe Co-TNTs may be an efficient and green heterogeneous catalyst for the degradation of organic pollutants, and this study provides insights into the rational design and development of alternative catalysts for wastewater treatment.
