Metal Site and Size-Controlled BTC-Based MOF as Cysteine Oxidase Mimic for Self-Cascade Detection of Cysteine and Hg2+

“…From Figure S3B, the C 1s spectrum was fitted into three peaks at 284.81, 286.21, and 288.75 eV corresponding to the C–C, C–O, and CO, respectively . The O 1s spectrum was fitted into two weak peaks at 532.21 and 533.65 eV in Figure S3C, which were assigned to the O–CO/CO and −OH/C–O, respectively Figure S3D displays the sharp characteristic peaks at 935.70 and 955.60 eV of Cu 2p, which were attributed to Cu 2+ 2p 3/2 and Cu 2+ 2p 1/2 , respectively, suggesting only Cu 2+ sites existed in Cu-BTC. , All of the above results demonstrated the effective bonding of the ligands to the catalytic center.…”
