Influence of synthesis methods on physical and photocatalytic properties of Bi2WO6 for decomposition of organic dyes and Cr(VI) reduction

A Post‐Spinel NaFeSnO4 as Novel Narrow Band Gap Photocatalyst for Visible Light Assisted Decomposition of Crystal Violet Dye

“…The terminologies used in equation such as α, h, ν and n are similar as those explained in our earlier work. [14] N 2 absorption study…”

“…The lower emission intensity observed in PL spectrum of NaFeSnO 4 confirms the enhanced charge separation efficiency than Fe 2 O 3 and SnO 2 . [14,34] NaFeSnO 4 like materials are more conductive due to alkali cations than SnO 2 and Fe 2 O 3 that could mobilize the electrons and holes and thereby inhibiting their recombination. [35]…”

“…[12,13] After the discovery of TiO 2 as photocatalyst several perovskite based and other catalysts such as Bi 2 WO 6 , CuWO 4 , SrTiO 3 , CaTiO 3 , NaTaO 3 , PbTiO 3 , ZnSnO 3 , SrSnO 3 , CaSnO 3 , BaSnO 3 , were introduced and demonstrated to be efficient photocatalysts under UV/visible region. [14][15][16][17][18][19][20][21][22][23][24] Recent reports emphasized the use of NaFeTiO 4 as a novel photocatalyst which utilizes the 1D channels present in the structure as active center and has improved activity than the single component oxides (Fe 2 O 3 and TiO 2 ). [25] It was observed that the tertiary or ternary mixed metal oxide photocatalysts were more active than binary metal oxide photocatalysts.…”
