InNbO 4 nanoparticles characterized by high crystallinity and particle sizes in the range of 10–30 nm (see TEM image) are synthesized by a soft‐chemistry route involving the solvothermal reaction of indium acetylacetonate and niobium chloride in benzyl alcohol at 200 °C. The as‐synthesized nanopowders offer a high photocatalytic activity under illumination with visible light.
