Abstract
[Cd3(tp)3(bmi)2] (SUSE-1) showed effective photocatalytic performance for the disintegration of dyes. A plausible mechanism for the degradation toward MB was suggested by the trapping method and LC-MS studies.

•A new 3D typical 8-connected bcu-type network was designed and synthesized.•SUSE-1 showed efficient photocatalytic activity for dyes.•The possible degradation intermediates were identified by LC-MS.
A new metal–organic framework (MOF), namely [Cd3(tp)3(bmi)2] (SUSE-1, SUSE = Sichuan University of Science & Engineering) (H2tp = 1,4-dicarboxybenzene acid and bmi = 1,3-bis(2-methylimidazolyl)pentane), has been synthesized. It exhibits a typical 8-connected bcu-type network with [Cd3(COO)6(bmi)4] nodes. SUSE-1 showed effective photocatalytic performance for the disintegration of the dyes Rhodamine B (Rh B), methyl orange (MO) and methylene blue (MB). In addition, a plausible mechanism for the degradation of MB was suggested from the results of the trapping method and LC-MS studies.
