Novel CoTiO3/Ag3VO4 Composite: Synthesis, Characterization and Visible-light-driven Photocatalytic Activity

Novel CoTiO3/Ag3VO4 Composite: Synthesis, Characterization and Visible-light-driven Photocatalytic Activity

A novel CoTiO3/Ag3VO4composite is successfully synthesized by ethylene glycol-mediated route/hydrothermal method. X-ray diffraction study suggests that the composite is formed with high purity. The presence of Ag3VO4irregular agglomerates and CoTiO3rods in the composite is evidenced by field emissio...
