Abstract
On metal oxide cluster nodes of metal-organic frameworks (MOFs), sites not bonded to linkers (e.g., defects and structural vacancies) control reactivity and catalysis. Attention has been focused on isolated, individual sites, but pair sites have been largely overlooked. We now show that the MOF hcp UiO-66, which incorporates dimeric Zr6O8 nodes bridged by μ2-OH groups, is an excellent platform for identifying and controlling adjacent sites consisting of OH groups and Zr4+ sites, which catalyze tert-butyl alcohol dehydration much more rapidly than isolated single sites.

Abstract
The role of alumina nanoclusters as a catalyst on the reactivity of alkyl halides has been explored. The thermochemical data obtained from Density Functional Theory (DFT) calculations and the analyses of the transition structures reveal that, between the two competing reactions, elimination (via E2) versus dissociative addition (via SN2), elimination is the kinetically controlled one and thus at room temperature, olefin is the major product. The results are in excellent agreement with the recent experimental observation where more than 97% of ethylene is formed at room temperature with the reaction of ethyl fluoride over an alumina surface, although the dissociative addition product is being thermodynamically more stable. We have tried to rationalize the fact by using alumina clusters of different sizes as well as different alkyl halides having β-H for elimination. It has been shown that, during the elimination (E2) pathway, the transition structure is oriented in such a way that the eliminating halogen and the β-H are in the interacting position with the three-centered Al and two-centered O atoms, respectively, where the Lewis acid/base interaction is the main guiding factor. We have also shown a possible pathway for regenerating the catalyst. Finally, the possibility of the reactions has been tested in the presence of H2O to mimic the same on the hydrated alumina surface.

Abstract
The methanol-to-olefin (MTO) process allows the conversion of methanol/dimethyl ether into olefins on acidic zeolites via the so-called hydrocarbon pool mechanism. However, the site and mechanism of formation of the first carbon-carbon bond are still a matter of debate. Here, we show that the Lewis acidic Al sites on the 110 facet of γ-Al2O3 can readily activate dimethyl ether to yield CH4, alkenes, and surface formate species according to spectroscopic studies combined with a computational approach. The carbon-carbon forming step as well as the formation of methane and surface formate involves a transient oxonium ion intermediate, generated by a hydrogen transfer between surface methoxy species and coordinated methanol on adjacent Al sites. These results indicate that extra framework Al centers in acidic zeolites, which are associated with alumina, can play a key role in the formation of the first carbon-carbon bond, the initiation step of the industrial MTO process.
