摘要
Let's facet it: TiO 2 mesocrystals (MCs; see figure) enclosed by (101) and (001) facets can be synthesized by a facile green approach and the ratio of (101)/(001) can be tuned simply by adjusting the solvothermal periods. The photocatalytic activity of TiO 2 MCs exposing high proportions of (101) facets possess higher photocatalytic activity than those with lower facets; this can be attributed to the synergistic effect of Ti 3+ and the (101)/(001) facet ratio.
