Gas-Solid Phase Reaction Derived Silver Bismuth Iodide Rudorffite: Structural Insight and Exploring Photocatalytic Potential of CO₂ Reduction.

ABSTRACT: Photocatalytic reduction of CO₂ is a promising strategy to mitigate the effects of global warming by converting CO₂ into valuable energy-dense products. Silver bismuth iodide (SBI) is an attractive material owing to its tunable bandgap and favorable band-edge positions for efficient CO₂ photoreduction. In this study, SBI materials, including AgBi₂I₇, AgBiI₄, Ag₂BiI₅, and Ag₃BiI₆ are first synthesized, through gas-solid reaction by controlling the stoichiometric ratio of reactants. The X-ray absorption near edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) results revealed that the distance between Ag-I is proportional to the degree of Ag ions delocalizatio
