7844 622 TiO2/Bi2WO6/Ag heterojunction 200 nm TEM After coating the TiO2 hollow nanostructures on the surfaces of SiO2 microspheres with the sol–gel reaction of TBOT and selective etching processes of NaOH, the average sizes were increased to 370 nm (Fig. 1D, E). Fig. S3 showed a typical TEM image of Ag nanocubes with an average size of about 76.2 nm.
