Preparation, Characterisation, and Photocatalytic Behaviour of Co-TiO2 with Visible Light Response

Figure 8

Visible light ( 𝜆 > 4 5 0  nm) photodegradation of 0.8 mM 2,2-bis(4-hydroxyphenyl) propane (Bisphenol A), as a function of time in aqueous suspensions of TiO2 and Co(x%)-TiO2, where the degree of doping x% is 0.5. The final calcination temperature was 400°C for 30 minutes.
