Enriched Catalytic Activity of TiO<sub>2</sub> Nanoparticles Supported by Activated Carbon for Noxious Pollutant Elimination

Cleaning wastewater has become one of the most serious issues for a number of scientists and researchers in recent years, as water is the most basic need for the daily life of humans. There has been a focus on the removal of noxious pollutants from wastewater effluents by using nanocatalysts owing t...

There has been a focus on the removal of noxious pollutants from wastewater effluents by using nanocatalysts owing to their unique physicochemical actions and stability.

The degradation efficiency of the as-prepared nanocatalysts against the very toxic but rarely studied organic textile dye pollutant RO 84 was investigated and 97% efficiency were found for the AC-TiO<sub>2</sub> as compared to pure TiO<sub>2</sub>, which is a highly appreciated finding in the catalytic dye degradation application domain.
