- Title

- Abstract
The defect pyrochlore KTaWO6 has been used to systematically investigate the effect of SnII incorporation conditions on the band structure and subsequent photocatalytic properties. Different tin precursors show varying influence on the resulting band gap. While the optimum conditions diminish the band gap by up to 1.4 eV, the increase in visible light absorption does not correlate with an increase of photocatalytic activity. KTaWO6 with defect‐pyrochlore structure has been used to investigate the influence of tin exchange conditions on band gap reduction, by up to 1.4 eV, and the effect on photocatalytic hydrogen production.
