(A,B,D) TEM micrographs and (C,E) XRD diffractograms of (A–C) hexagonal CMK-3 and (D,E) cubic CMK-1 materials. TEM views of CMK-3 show both the hexagonal packing (A) and the long mesopores (B), while XRD data include also the diffractograms corresponding to the mother SBA-15 (C) and MCM-48 (E) mesoporous silica templates. (F) Pore size distributions for CMK-3 and CMK-1. Data have been reproduced/adapted from [38] (A,B), [40] (C), [39] (D), [16] (E), and [33,41] (F).
