Atmospheric-pressure cold plasma for synthesizing Ag modified Degussa P25 with visible light activity using dielectric barrier discharge

- Ag/TiO2 visible light photocatalyst was successfully fabricated using dielectric barrier discharge at atmospheric pressure.
- XPS and XRD spectra proved that Ag ions were completely reduced to metallic Ag nanoparticles.
- The Ag/TiO2 catalyst fabricated by DBD cold plasma exhibited a high activity for MB degradation under visible light (λ > 420 nm).
- Atmospheric-pressure DBD cold plasma was highly efficient for preparation of supported metallic Ag catalyst.
