| Abstract: | The 3D mesoporous TiO2 microspheres were fabricated in a one-step hydrothermal process without templates,and the microspheres were subsequently characterized by XRD,TEM,HRTEM and BET techniques.The photocatalytic degradation activity of the 3D mesoporous TiO2 microspheres was evaluated by comparison to the commercial P25 on the degradation of bisphenol A(2,2-bis(4-hydroxyphenyl) propane,BPA),and the phase transformation of TiO2 at different temperatures and thermal gravimetric analysis(TGA) were also studie... |
| Keywords: | mesoporous TiO2 microspheres hydrothermal method photocatalysis bisphenol A |
