TiO 2 /nanoclinoptilolite (TiO 2 /NCP) was prepared by the mediation of hexadecyltrimethylammonium (HDTMA) as surfactant and used as an effective heterogeneous nanocatalyst for the preparation of substituted 2‐aminotiophenes. The modified HDTMA/NCP was impregnated with titanium(IV) chloride solution followed by calcination at 500 °C for 20 h. The obtained nanocomposite was characterized using Fourier transform infrared spectroscopy, field emission scanning electron microscopy, inductively coupled plasma optical emission spectroscopy and X‐ray diffraction. Moreover, the prepared nanocomposite had high stability and recoverability under mild and solvent‐free conditions.
