Supplementary Figure S1: SEM images of the middle region of the membranes’ cross side synthesized after
different periods. a) 1 h, small crystals grow along the channel wall, b) 3 h, many bigger crystals stuff the channels,
c) 9 h, channel walls have been corroded badly, some even disappeared, and d) 12 h, the whole channels has been
transformed to big crystals.

autoclave (red: unmilled, blue: milled): the crystals show no specials peaks of MIL-53, indicating that there are
no crystals lost in the reaction solution.
