459Ag-MA2.5μmTEMOne can note from Fig. 1A that the original products of Ag-MA nanocomposites could exhibit uniform rod-like profile with the side width of about 2.5 μm, with the mesoporous structure as revealed in the amplified view (insert), which could also be witnessed clearly from the TEM images (Fig. 1C).
