“…The spectrum of the composite HKUST-1@BPS sample 2 (red) contains absorption bands at 1673, 1587, 1450, 1420, 1394, 1359, 1332, 1251, 1106, 1022, 939, and 885 cm −1 . The spectrum of the composite HKUST-1@BPS sample 3 (blue) contains absorption bands at 1691, 1654 (sh), 1587, 1499, 1450, 1420, 1390, 1251, and 1177 cm −1 , which refer to the vibrations of the framework in these HKUST-1@BPS composite materials [ 69 , 70 , 72 , 76 , 77 , 78 , 79 , 80 ]. The same area includes absorption bands from bending vibrations of CH 3 , i.e., 1454 (antisym.)…”
