Highly ordered macroporous titania films (see Figure) can be prepared over large areas using colloidal silica spheres as a template. This template material has a number of advantages over the more commonly used polystyrene spheres, such as easy removal of the template by immersion in a warm NaOH solution and shrinkage of the macroporous framework by less than 3 %.
