Figure 3. UV/Vis absorption and photocatalysis characterization of AgnX@Ag.

Figure 3

(a and b) UV/Vis diffuse reflectance spectra of the as-prepared Ag3PO4@Ag, Ag2CrO4@Ag, AgBr@Ag, and a series of AgCl@Ag in the aqueous suspension; insets in b are the partial enlarged details of C-1 and C-3 showing the difference in near ultraviolet region. (c) Photodecomposition of methyl orange (MO) without and with the presence of as-prepared Ag3PO4@Ag, Ag2CrO4@Ag, AgCl@Ag and AgBr@Ag. (d) Photodecomposition of MO over AgCl@Ag samples C-1, C-2, C-3, and C-4. (e) Photodecomposition of MO over AgCl@Ag during the 5th recycling experiment. All photodecomposition experiments were carried out in MO aqueous solution (10 mg·L−1) under visible-light irradiation (λ ≥ 400 nm).
