Microwave-hydrothermal synthesis of Co-doped FeS2 as a visible-light photocatalyst
Source abstract
Abstract
Co-doped FeS2 composites were successfully synthesized through a facile microwave-hydrothermal process. The products were characterized by X-ray diffraction, X-ray Photoelectron Spectroscopy, field emission scanning electron microscope, UV–Vis diffuse reflectance spectra, and Raman spectroscopy. Cobalt doping didn’t change the basic structure of pyrite FeS2. But the spherical FeS2 product changed into some aggregated laminar particles. The Co-doped FeS2 product exhibited higher absorption in visible-light region and the photocatalytic performance was greatly enhanced. The Co0.333Fe0.667S2 product could decompose 48.9 % methylene blue within 210 min, which was 36.5 % higher than that of the pristine FeS2.
