Enhanced Photodecomposition of Methylene Blue in Water with Sr_1−xK_xTiO_3−δ@PC-polyHIPEs under UV and Visible Light

Figure 2

SEM micrographs of (a) PC-polyHIPEs; (b) enlarged PC-polyHIPEs; (c) Sr_0.7K_0.3TiO_3−δ@PC-polyHIPEs; (d) Sr_0.7K_0.3TiO_3−δ. The long red arrow in Figure 2(b) shows that the PC-polyHIPEs own ca. 100 μm pores and the short red arrow shows that the PC-polyHIPEs own ca. 30 μm windows.
