Palladium nanoparticles deposited on a chromium terephthalate MIL-101 is a highly efficient multifunctional catalyst for the one-step synthesis of methyl isobutyl ketone, with significantly higher activity than palladium on traditional materials, such as metal oxides and zeolites.

A new microporous amino-functionalized metal-organic framework has been synthesized by direct self-assembly, which exhibits high moisture-stability, acceptable capacity, and unprecedented high selectivity for CO(2) over CH(4), suggesting its potential application in gas separation processes like natural gas and biogas upgrading.

Ein Palladium‐Heterogenkatalysator mit dem Metall‐organischen Gerüst MIL‐101 als Träger vermittelt effiziente Kupplungen in Wasser; so lieferten Suzuki‐Miyaura‐Kreuzkupplungen und Ullmann‐Homokupplungen von substituierten Arylchloriden hohe Ausbeuten. Der Katalysator lässt sich darüber hinaus leicht zurückgewinnen und wiederverwenden (siehe Bild; Cr blau, O rot, C weiß).

Using amino acid hydrochloride salt as a catalyst, the coupling reaction of CO 2 with epoxides could proceed smoothly to give cyclic carbonates in very good yields and high selectivity. The reaction conditions such as the pressure of carbon dioxide, reaction temperature, time and catalyst loading were carefully investigated.
