Two Oxide Semiconductors, Namely, Bismuth Vanadate (BiVO4) and Silver Bismuth Tungstate (AgBiW2O8) Were Prepared by Solution Combustion Synthesis and their Attributes as Photocatalysts Were Comparatively Evaluated. A Key Conclusion of this Study Is that the Optical Characteristics Alone Provide only a Partial Glimpse into the Applicability of a Given Semiconductor for Solar Energy Conversion and Environmental Remediation. Thus while the Optical Bandgap of Bivo4 Is Lower than Agbiw2o8 (and Thus Is Able to Harness a Greater Portion of the Solar Spectrum), its Photocatalytic Activity for the Degradation of a Dye Is Inferior. this Finding Underlines the Fact that other Characteristics of the Semiconductor (band-Edge Alignment, Surface Quality Etc) Also Play as Critical a Role as the Optical Properties. |
