A Novel Green Approach for Fabrication of Ag2CrO4/TiO2/Au/r-GO Hybrid Biofilm for Visible Light-Driven Photocatalytic Performance

Development of cutting edge materials using a benevolent ecologically cordial methodology is an ideal approach for heterogeneous visible light photocatalysis. A new biogenic photocatalyst was developed by coupling titanium dioxide (TiO2) decorated elongated rhombic shape silver chromate (Ag2CrO4) with gold (Au) and reduced graphene oxide (r-GO) for dye degradation applications under visible light. An ecologically positive methodology was utilized to develop the quaternary Ag2CrO4/TiO2/Au/r-GO nanostructures biofilm with gold and reduced graphene oxide (r-GO) via impregnation and in situ reduction technique in presence of Acacia gum. The structural properties and morphology of the Ag2CrO4/TiO2/Au/r-GO nanostructures were described by several spectroscopic and microscopic methods such as XRD, XPS, ATR-FTIR, Raman spectroscopy and FE-SEM etc. Alteration with Au and r-GO decreased the band vitality and essentially improved the visible light ingestion of the quaternary Ag2CrO4/TiO2/Au/r-GO composite biofilm ph...
