AbstractAg-TiO2 nanocomposite consisting of Ag clusters on the surface of TiO2 nanocrystals has been prepared by an ethylenediamine-complexing silver mirror reaction, which employs ethylenediamine (C2H8N2) rather than ammonia as a complexing agent. In this synthesis, the reduction reaction is finely tuned by varying the C2H8N2/H2O volume ratio. With the C2H8N2/H2O volume ratio at 1:4, the reduction can proceed in a more controllable manner, and the emerging Ag atoms in solution directly deposit on TiO2 nanocrystal surfaces, while self-nucleation and growth of nuclei to large size of free-standing Ag nanoparticles cannot occur. The obtained Ag-TiO2 nanocomposite shows excellent catalytic activity for the reduction of p-nitrophenol (4-NP) into p-aminophenol (4-AP) by NaBH4.
