“…4a, the NMFA composites contained both the characteristics of AgSCN and NH 2 -MIL-53(Fe). Specifically, the vibrational bands located at 505, 707, 1069, and 2089 cm −1 represented the bending, symmetric stretching, bending overtones and asymmetric stretching vibrations of the SCN −1 group, 29 respectively. More precisely, the characteristic vibrational bands of 707 and 2089 cm −1 could be attributed to the S-C and C-N groups.…”
