摘要: Abstract Two new 2D metal–organic frameworks (MOFs), [Cd(bpy)(H2O)L]n (BUC-66) and {Co(bpy)(H2O)L]·H2O}2n (BUC-67), (H2L = cis-1,3-dibenzyl-2-imidazolidone-4,5-dicarboxylic acid, bpy = 4,4′-bipyridine), have been synthesized under hydrothermal conditions. These two MOFs were used to carry out photocatalytic Cr(VI) reduction organic pollutants degradation. The results revealed that both BUC-66 BUC-67 displayed outstanding performances with efficiency more than 98% within 30 min UV light irradiation, much better of commercial P25 (24%). Also, could photocatalytically decompose dyes. exhibited considerable activities in the Cr(VI)/organic dyes matrix. Upon illumination for 30 min, reached 100%, along dye (methyl orange) degradation being 85% 100% (BUC-67). Finally, a possible photocatalytical reaction mechanism proposed verified detail.
