Atomic layer deposition (ALD) and a photochemical method were used to coat polystyrene (PS) 3D‐Direct Opal (3D‐DO) structures on conductive ITO substrates. Firstly, 3D‐DO of PS were crystallized on ITO substrates to form the high surface‐to‐volume ratio template via a self‐assembly method. A low‐temperature ALD TiO<sub>2</sub> film was infiltrated onto the PS opal structure. Then, the PS template was removed by a thermal treatment in air at 450 °C for 5 h. Hollow anatase phase nanospheres were obtained, crystallized in a face centered cubic (FCC) lattice with the (111) plane oriented parallel to the substrate surface.
