Metallic Ag nanoparticles (Ag0) were successfully activated using a direct in situ electrochemical method before being supported on TiO2. Catalytic testing showed that 5 wt% Ag–TiO2 gave the highest photodegradation (94%) of 50 mg L-1 2-chlorophenol (2-CP) at pH 5 using 0.375 g L-1 catalyst within 6...
