TL;DR: An easy method is reported to prepare isolated gold atoms supported on functionalized carbon nanotubes and their performance in the oxidation of thiophenol with O2, showing that single gold atoms are not active, but they aggregate under reaction conditions into gold clusters of low atomicity that exhibit a catalytic activity comparable to that of sulfhydryl oxidase enzymes.

TL;DR: In this paper, two types of Lewis acid sites are shown to exist in Sn-beta zeolite: partially hydrolysed framework tin centers (Si O ) 3 Sn OH (sites A) and fully framework coordinated tin atoms Sn( Si O ) 4 (sites B).

TL;DR: The formation of hydroxyl radicals, either by irradiation with ultraviolet light or with the Fenton reagent, can speed up the formation of the crystallized zeolite by about a factor of 2.Radically faster synthesis Zeolite synthesis normally proceeds under basic conditions that allow the oxide bridges between aluminum and silicon atoms to break and reform.

TL;DR: It is shown that when methanol carbonylation competes with hydrocarbon formation, the first reaction occurs preferentially within 8MR channels, and that only the T3-O33 positions are selective and that this selectivity is due to the unusual orientation of the methoxy group in relation to the 8MR channel.

TL;DR: A heterogeneous catalyst consisting of Pd4 clusters with mixed-valence 0/+1 oxidation states, stabilized and homogeneously organized within the walls of a metal-organic framework (MOF) outperforms state-of-the-art metal catalysts in carbene-mediated reactions of diazoacetates, with high yields and turnover numbers.
