Enhanced photocatalytic degradation of methylene blue and adsorption of arsenic(<scp>iii</scp>) by reduced graphene oxide (rGO)–metal oxide (TiO₂/Fe₃O₄) based nanocomposites

Abstract

Hazardous methylene blue dye and As(<sc>iii</sc>) ions from wastewater are removed by the rGO and TiO₂/Fe₃O₄based binary and ternary nanocomposites, where ternary rGO–Fe₃O₄–TiO₂nanocomposite provides maximum degradation and adsorption of the pollutants.
