“…Between 108 8C and 270 8C, there were no significant weight losses on heating, indicating that the dehydrated material is thermally stable up to this temperature. [45] Above 270 8C, further weight losses are observed that are thought to be due to structural collapse.…”

A continuous flow reactor was developed for the synthesis of porous metal-organic frameworks (MOFs) under mild reaction conditions. Commodity hardware was used to assemble the device, giving it a great degree of flexibility in its configuration. The use of paraffin to encapsulate reactions and also ultrasonic treatment were employed to prevent clogging of the reactor. Reactor design was optimised through studies of the synthesis of zirconium carboxylate framework UiO-66. Synthesis of the aluminium carboxylate CAU-13 was also performed, to demonstrate the versatility of the device. Finally the reactor was used to synthesise a new cadmium phosphonate framework, bearing the STA-12 network.

“…Bending vibration of water molecules appear at 1631 cm −1 . [31] The adsorptive properties of as-prepared MOFs have been studied with N 2 at 77 K. The samples in Figure S7 exhibited type IV isotherms, with H3 typical hysteresis loop. These samples also exhibit C-H stretching vibrations and bending vibrations of CH 2 attached to nitrogen atoms, near 2960 and 1457 cm −1 , respectively.…”

phosphonate-based bimetallic metal-organic frameworks, namely STA-12(M 1 , M 2 ) (M 1 , M 2 = Mn, Fe, Co), show photocatalytic activity for the degradation of Rhodamine B (RhB) and Methylene blue (MB) from aqueous solution under natural sunlight irradiation. The degradation of the dyes, appears to be faster with STA-12(Fe, Mn) than other synthesized MOFs. Thus, photo-Fenton oxidative discoloration of dyes has been studied by H 2 O 2 catalyzed with the STA-12(Fe, Mn). The process is first order with respect to dyes and the synergistic index in the STA-12(Fe, Mn)/sunlight/H 2 O 2 system reached as high as 472%.Mineralization of dyes was discussed by spectroscopic and TOC measurement. Besides, the efficiency of STA-12(Fe, Mn) used in photocatalytic process was attentively investigated through the characterization of reactive radicals, the stability and reusability of the photocatalyst, also the effect of operational parameters such as H 2 O 2 dosage, solution pH and initial dye concentration.This work demonstrates the first example of facilitating photo-Fenton-like excitation of H 2 O 2 via phosphonate based mixed metal organic frameworks as photocatalysts and explained a new opportunity for solar-induced AOP environmental remediation and protection.
