Sol-gel technology was used to fabricate heterogeneous Fe2O3-In2O3 nanocomposite consisting of a-Fe2-xInxO3 solid solution and two modifications of y-Fe2O3–cubic (Cy-Fe2O3) and tetragonal (Qy-Fe2O3). The material is shown to be active in adsorption and catalytic processes and promising for sensorics.
