| description | This study was conducted to evaluate the catalyst efficiency to activate peroxymonosulfate for the
removal of dyes, mainly Methyl Violet, Toluidine Blue O, and Acid Orange 7. Dyes, particularly
those used in the textile industry, are considered organic pollutants. The discharge of wastewater
from the textile industry may cause severe environmental impacts. The subject of catalyst is a topic
of interest, due to its unique morphology that can affect the rate of catalysis. Cobalt oxide catalyst is
a commonly used, low-cost transition metal oxide that was widely used in the air purification field.
Therefore, this research investigates the efficiency of different types of Cobalt Oxide as a catalyst to
activate PMS for the removal of dyes. By employing a comprehensive analytical approach, this
study evaluates cobalt oxide synthesised via hydrothermal and simple chemical precipitation. The
findings revealed that the catalytic activity is greatly influenced by its surface area, morphology,
and elemental composition, with higher surface area and specific morphologies of nanorods and
nanosheets demonstrating better dye degradation performance. |
