Structure and optical properties of Fe2TiO5/Ag/C nanocomposites as photocatalyst materials

Abstract

Photocatalysis has attracted attention, utilizing solar energy directly to catalyze chemical reactions. This research synthesized Fe2TiO5/Ag/C nanocomposites as photocatalyst material using a wet milling process and confirmed with comprehensive characterizations. Impregnation Ag/C produced crystal defects Fe2TiO5, resulting smoother amorphous surface with increased surface area and higher volume and size of pores. The optical properties of Fe2TiO5/Ag/C absorb light at 600 nm with a band gap of 2.04 eV and thus can be classified as semiconductor materials sensitivity in visible light. Finally, the Schottky barrier and surface plasmon resonance effect of Ag/C was proposed to describe the mechanism of the photocatalytic process on the Fe2TiO5/Ag/C.
