An investigation of silver-nanoparticle-modified TiO2 substrates for photocatalytic oxidation in wastewater treatment

Abstract

ARTICLE HIGHLIGHTS • This study compares the photocatalytic activity of silver-nanoparticle-coated TiO2 substrates under solar irradiation with that of undecorated TiO2. • A brief morphological, optical, and structural analysis confirms that silver nanoparticle decoration enhances catalytic performance. • TiO2 substrates coated with Ag nanoparticles hold potential for environmental applications, particularly in the photocatalytic degradation of methylene blue dye, an organic compound.
