Nanocomposite AgBr@HPU-4 was synthesized based on a 3D Cu-MOF, {[Cu(L) 0.5 (H 2 O) 2 ]·4H 2 O} n (HPU-4) through a facile reaction route and confirmed by XRD, TEM, SEM. UV–Vis absorption spectrum indicates that AgBr@HPU-4 nanocomposite has strong optical capability nearly in the whole range of visible light spectrum. The as-prepared AgBr@HPU-4 photocatalyst, as compared to AgBr or HPU-4 , exhibits enhanced photocatalytic activity towards the degradation of Methylene Blue and Methyl Orange dyes.

A Cu(I)/Cu(II) 3D framework, {[(CuII) 3 (CuI) 3 (pbt) 3 Cl 2 ]·ClO 4 ·H 2 O} n ( HPU-3 ) (H 2 pbt = 5′-(pyridin-2-yl)–2H,4′H-3,3′-bi(1,2,4-triazole)), has been synthesized by using solvothermal method. UV–Vis absorption spectrum indicates that HPU-3 has strong optical capability nearly in the whole range of visible light spectrum. HPU-3 photocatalyst exhibits good photocatalytic activity toward the degradation of Methylene Blue and Methyl Orange dyes. [ABSTRACT FROM AUTHOR]

This paper reports a metal ion-exchange material which can significantly enhance the degradation of acetamiprid and methylene blue. [Display omitted] A Metal-Organic Framework (MOF) by the formula of {[Cd 4 (L) 2 (H 2 O) 3 ]·4·.5H 2 O} n (HPU-15-Cd) (H 4 L = 5, 5′-oxydiisophthalic acid) has been synthesized via solvothermal method. The central ions of HPU-15-Cd can occur ion-exchange with Co2+/Cu2+ ions to form the isostructural HPU-15-Co, HPU-15-Cu in a single-crystal-to-single-crystal fashion. Photocatalytic experiments showed that HPU-15-Co, HPU-15-Cu had better photocatalytic activity for the degradation of acetamiprid (ACT) and methylene blue (MB) than HPU-15-Cd. The reason is that the band gap width of HPU-15-Co and HPU-15-Cu is narrow, which makes it have higher absorption and utilization of UV–visible light. Besides, HPU-15-Cd, HPU-15-Co, HPU-15-Cu have excellent stability, and the catalytic effect of HPU-15-Cu are basically unchanged after three cycles of catalytic degradation of ACT and MB.
