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