Preparation and Characterization of F Free-standing Hierarchical Porous TiO2 Monolith Modified with Graphene Oxide

 

Lei et al has develop a hierarchical porous TiO2 monolith with well-defined macroporous and homogeneous mesoporous structure in a sol-gel phase separation method. Graphene oxide (GO) is added to the monolithic TiO2and P123 has been used to obtain an ordered porous structure.

 

They found that the TiO2 monolith is mainly composed of 10 nm anatase crystallines, and has a hierarchical porous structure with 3.6 nm mesopores and 2-8µm macropores. P123 and GO play an important role in structural integrity and stability of the monolith, and the pore size can be tailored by adjusting the starting compositions. The BET specific surface area can reach 163 m2/g. The porous TiO2 monolith remains intact after being applied for the discolorization of MO solution.
