The challenge of fine compositional tuning and microstructure control in complex oxides is overcome by developing a general two‐step synthetic approach. Antimony‐alloyed bismuth vanadate, which is identified as a novel light absorber for solar fuel applications, is prepared in a wide compositional range. The bandgap of this quaternary oxide linearly decreases with the Sb content, in agreement with first‐principles calculations.
