• Ag/TiO2 nanocomposites with controlled crystallization and properties were prepared by a simple solvothermal method. By using the same raw materials with different ratio and reaction conditions, the morphologies and crystallization of nanocomposites can be tuned. The components of the products were analyzed by TEM and XRD methods respectively. The as-prepared Ag/TiO2 nanocomposites were used as surface-enhanced Raman spectroscopy (SERS) substrate to be evolved for detection of environmental organic dyes pollutants (CV and RhB) with excellent recyclability. Furthermore, it also showed enhanced catalytic performance of nitrophenol compounds (4-NP). After that, the Ag/TiO2 nanocomposites were also used as an active substrate and a superior catalyst for reduction of 4-NTP monitored by Raman spectroscopy.
