Figure 6. Formation process of SnO2-rGO monolayer porous film.

Figure 6

(a) The existence modes of GO sheets; (b) SnO2/H2SnO3 particles was forming on the surface of PS microspheres and GO sheets under UV; (c) state of the colloidal monolayer and composite shells on the ceramic tube; (d) condensed composite film on the tube after the second irradiation; (e) SnO2-rGO monolayer porous film after removal of the PS microspheres; (b0) and (b0r) SEM image of the back side and the right side, respectively, of the composite film after irradiated 30 min; (b1) Photochemical behaviours induced by SnO2 under UV.
