• TiO2 nanohoneycomb was fabricated by solution-based nanosphere lithography. TiCl4 solution was used as a precursor to fill in the interspace of the self-assembled polystyrene nanosphere mask. After removing the polystyrene (PS) nanosphere monolayer by heating, an anatase nanohoneycomb was formed. A more uniform nanohoneycomb was obtained by using $t$-butanol as the solvent for TiCl4 because of its better wetting with the nanospheres. UV–visible spectra of the nanohoneycombs showed that there were two absorption edges at 320 and 470 nm. The photocatalytic activity measurement showed that the nanohoneycomb had a better photodecomposition efficiency than the film.
