Nanosized Co3O4/SiO2 for heterogeneous oxidation of phenolic contaminants in waste water
TL;DR: In this article, the physicochemical properties of three Co/SiO2 catalysts were characterized by several techniques, such as XRD, SEM, TEM, FT-IR and FT-Raman, and the catalytic activity in heterogeneous activation of peroxymonosulphate to produce sulphate radicals for phenol degradation was investigated.

Heterogeneous catalytic wet peroxide oxidation systems for the treatment of an industrial pharmaceutical wastewater.
TL;DR: Assessment of the treatment of wastewater coming from a pharmaceutical plant through a continuous heterogeneous catalytic wet peroxide oxidation (CWPO) process using an Fe(2)O(3)/SBA-15 nanocomposite catalyst indicates that the catalyst shows high activity in terms of TOC mineralization, which enhances its biodegradability, and favours the possibility of a subsequent coupling with a conventional biological treatment.
