Abstract The commercialization of the photocatalysis technology requires that synthesis photocatalytic material is easy to scale up. Thus, from earth‐abundant minerals represents one plausible solution obtain materials by a scalable process with lower environmental impact. So far, most promising photocatalyst for this application titanium dioxide (TiO 2 ), which can be obtained ilmenite ore; however, its usually implies toxic solvents and complicated reaction conditions. here proposed an optimized method extract higher amounts TiO multivariable Plackett‐Burman design experiments considering mass ore precursor, addition phosphoric acid (H 3 PO 4 digestion temperature, amount base adjust pH, final thermal treatment. From design, it was possible minimize heat treatment used favor (rutile) content presence additional phases iron oxides (Fe O ) act as co‐catalyst enhance activity. activity /Fe composites investigated in four model reactions solar fuels evolution CO reduction) remove endocrine water pollutants (bisphenol A dyeing water), using visible natural irradiation, respectively.
