3.6 Conclusion
Herein, to sum up, we have reviewed plenty of representative literatures about recent
advances in photocatalysts over the highly dispersed TiO 2 in mesoporous materials.
Although TiO 2 possesses specific properties, it is limited in photocatalysis because
of its narrow bandgap. Thus, the doping modification on mesoporous TiO 2 materials
proves to be an effective way to enhance its photocatalytic performance. Meanwhile,
synthesizing mesoporous TiO 2 –SiO 2 , Ti–MOFs, and Ti–SiO 2 materials is another
feasible way to achieve this goal. Based on the analysis of mechanism of these
systems, it gives the researchers a promising future. The achieved progress in this
field indicates that researchers can either be able to extend the photoresponse to the
visible region or apply them to practical application, such as water splitting, degradation of pollutants and decomposition of greenhouse gas (CO 2 , NO, NO 2 ).
