Abstract The Cu₂O/TiO₂ composites with two different morphologies were synthesized through adjusting the concentration of tetra-n-butyl titanate (TBOT), and were subsequently characterized by means of X-ray diffraction (XRD), fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The resultant composites’ antibacterial properties and ammonia removal performances were also determined by the experiment. It has been observed that the membranous TiO₂ turns to granuliform on the surface of Cu₂O nanoparticles while the TBOT concentration increased from 0.04% to 0.12%. On the other hand, compared with the pure Cu₂O, the Cu₂O/TiO₂ composite with membranous surface exhibited better antibacterial properties, and the antibacterial properties of the sample with granuliform surface slightly reduction. Moreover, compared to pure Cu₂O, the Cu₂O/TiO₂ composites with either membranous or granuliform surface performed more actively in ammonia removal, but the latter had a better removal performance than the former.
