Effectiveness of metal oxide catalysts for the degradation of 1,4-dioxane.

ABSTRACT: 1,4-dioxane, commonly used as a solvent stabilizer and industrial solvent, is an environmental contaminant and probable carcinogen. In this study, we explored the concept of using metal oxides to activate H₂O₂ catalytically at neutral pH in the dark for 1,4-dioxane degradation. Based on batch kinetics measurements, materials that displayed the most suitable characteristics (high 1,4-dioxane degradation activity and high H₂O₂ consumption efficiency) were ZrO₂, WO _x /ZrO₂, and CuO. In contrast, materials like TiO₂, WO₃, and aluminosilicate zeolite Y exhibited both low 1,4-dioxane degradation and H₂O₂ consumption activities. Other materials (e.g., Fe₂
