Abstract

In this study, nano Gd(OH)3 was synthesized with the polyol method with gadolinium chloride hydrate (GdCl3·xH2O) and sodium hydroxide as precursors, and triethylene glycol (C6H14O4) as a surfactant. The material was characterized with XRD, SEM, TEM, TG-DTA, EDX techniques. Gd(OH)3 has the form of pure nanorods with a uniform size of 20 × 200 nm. The material was utilized as a catalyst in the advanced photochemical decomposition of red Congo as the UV/Gd(OH)3 and UV/H2O2/Gd(OH)3 system.
