Synthesis and Characterization of Bi2Ti2O7 with Fe addition: Examining the effects of Fe on photo driven hydrogen Production

摘要

This work presents a study on the visible light-driven photo-assisted hydrogen generation using a pyrochlore-type photocatalyst (A2B2O7). It includes an additional earth abundant element for boosting photoactivity. We have employed a wet chemical approach for the synthesis of the pyrochlore photocatalyst. The characterization of the material using surface and optical techniques indicate that Fe can be successfully incorporated into Bi2Ti2O7 (BTO) with varying concentrations. It will be shown that compared with plain BTO, the hydrogen yield is improved by 175% with 1%Fe.
