Application of Titanium Dioxide-Graphene Composite Material for Photocatalytic Degradation of Alkylphenols

Figure 8

Extracted chromatograms wastewater (a) after 3 hours exposure of UV radiation without catalyst and (b) after addition of TiO2-graphene composite (1 : 0.1 ratio) with UV exposure for 3 hours. Peak identification: (1) 4-n-heptylphenol, (2) 4-nonylphenol (mixture of isomers), (3) 4-n-octylphenol.
