Composite supercapacitor electrodes based on carbon nanotubes, carbon black, and a metal–organic framework with iron(III) coordination centers [MIL‐100(Fe), MIL‐88B(Fe), or MIL‐53(Fe)] were prepared and tested with several aqueous electrolytes. A correlation between hydrated ion size and the electric response of the electrodes was found, which sheds light on how these materials work as energy‐storage devices. MIL‐100(Fe) shows the most promising results, and the capacitance obtained with the samples in the solutions used is higher than that of a mixture of carbon and nanotubes in the same solution. Unfortunately, shortcomings due to reductive dissolution still hamper the long‐term cyclability of the electrodes.

Chemically pure terephthalic acid can be substituted with waste PET as the linker source for MOF synthesis. PET depolymerisation and MOF formation can occur simultaneously in water at high temperatures.

A smart catalyst that can be activated by UV-light was prepared by encapsulating Metal-Organic-Framework (MOF) particles in microcapsules with a photocleavable polyurea shell. Addition of palmitic acid as a modulator during the synthesis of the Fe-terephthalate MOF MIL-88B(Fe) yields MOF particles with a hydrophobic surface. These particles can be successfully encapsulated via interfacial polymerization, as proven by a combination of PXRD, SEM and EDX techniques. By the incorporation of photolabile groups in the polymer shell, UV light can be employed to trigger degradation of the capsules, releasing the catalytic load. Catalyst activation triggered by UV light was monitored by recording the rates for catalytic tetramethylbenzidine (TMB) oxidation with H 2 O 2 . The reactivity could be controlled by tuning irradiation time, UV intensity or MOF loading. The activity of the capsules was up to 90 times higher after irradiation.

We report the production of biobased plasticizers starting from citric acid (CA) by a two step process comprising dehydration hydrogenation of CA followed by a Fischer esterification. The use of...
