By templating Ag + ‐induced supramolecular assembly at different temperatures, porous TiO 2 –Ag nanotubes and nanospheres are fabricated in a controlled manner due to the effect of Rayleigh instability. Compared with traditional TiO 2 nanoparticles, TiO 2 –Ag nanostructures above show much more extensive visible light absorption and exhibit the noticeably plasmon‐enhanced photocatalysis because of the existence of Ag nanoparticles.
