6. Future prospects

A great deal of research has been devoted to improving the performance of titanium dioxide, either by enhancing its porosity and adsorption properties, or by increasing its efficiency in visible light.

6.1 Structural or morphological changes

Several types of micron or submicron environments for confining photocatalytic reactions have been described: massive micromesoporous materials based on inorganic porous structures (zeolites, mesoporous silicas), mesoporous films, structured membranes, inorganic foams, monoliths, hierarchical macromesoporous structures, porous hollow spheres and beads...
