A new post-synthetic polymerization strategy makes metal-organic frameworks more stable

Safak Bulut, Emad Oveisi, Mehrdad Asgari, Daniel Teav Sun, Wendy Lee Queen, Li Peng, Olga Trukhina, Shuliang Yang, Abbas Jamali

Metal-organic frameworks are of interest in a number of host-guest applications. However, their weak coordination bonding often leads to instability in aqueous environments, particularly at extreme pH, and hence, is a challenging topic in the field. In thi ...

An In-Situ Neutron Diffraction and DFT Study of Hydrogen Adsorption in a Sodalite-Type Metal-Organic Framework, Cu-BTTri

Safak Bulut, Michele Ceriotti, Mehrdad Asgari, Wendy Lee Queen, Olga Trukhina, Pascal Alexander Schouwink, Ilia Kochetygov, Shuliang Yang, Rocio Semino Barbaresi

Herein we present a detailed study of the hydrogen adsorption properties of Cu‐BTTri, a robust crystalline metal–organic framework containing open metal‐coordination sites. Diffraction techniques, carried out on the activated framework, reveal a structure ...

Efficient cleavage of aryl ether C–O linkages by Rh–Ni and Ru–Ni nanoscale catalysts operating in water

Paul Joseph Dyson, Vassily Hatzimanikatis, Duncan Thomas Lindsay Alexander, Ning Yan, Antoine Philippe Van Muyden, Safak Bulut, Georgios Savoglidis, Sviatlana Siankevich

Bimetallic Ru–Ni and Rh–Ni nanocatalysts coated with a phase transfer agent efficiently cleave aryl ether C–O linkages in water in the presence of hydrogen. For dimeric substrates with weaker C–O linkages, i.e. α-O-4 and β-O-4 bonds, low loadings of the pr ...

Metal-Organic-Framework-Derived Co3S4 Hollow Nanoboxes for the Selective Reduction of Nitroarenes

Safak Bulut, Emad Oveisi, Daniel Teav Sun, Wendy Lee Queen, Li Peng, Shuliang Yang

MOF-derived Co3S4/CN hollow nanoboxes (CN=nitrogen-doped carbon) was used to catalyze the chemoselective reduction of nitroarenes to anilines under mild reaction conditions with H-2 as the reducing agent. The catalyst provides high conversion efficiencies ...

MOF-Derived Cobalt Phosphide/Carbon Nanocubes for Selective Hydrogenation of Nitroarenes to Anilines

Safak Bulut, Emad Oveisi, Mehrdad Asgari, Daniel Teav Sun, Wendy Lee Queen, Li Peng, Olga Trukhina, Shuliang Yang

Transition-metal phosphides have received tremendous attention during the past few years because they are earth-abundant, cost-effective, and show outstanding catalytic performance in several electrochemically driven conversions including hydrogen evolutio ...

Recent Advances of MOFs and MOF‐Derived Materials in Thermally Driven Organic Transformations

Safak Bulut, Wendy Lee Queen, Li Peng, Shuliang Yang

Owing to the almost boundless structural tunability, MOF and MOF‐derived catalysts have recently exhibited structures of higher complexity, and hence, have demonstrated activity in a wide array of organic transformations. These reactions have a broad range ...

Thiazolium carbene catalysts for the fixation of CO2 onto amines

Paul Joseph Dyson, Safak Bulut, Felix Daniel Bobbink, Mylène Soudani, Shoubhik Das

The catalytic N-formylation and N-methylation of amines using CO2 as the carbon source represents a facile and sustainable approach for the synthesis of pharmaceuticals and natural products. Herein, we describe highly effective and inexpensive thiazolium c ...

Aqueous-phase hydrogenation of alkenes and arenes: The growing role of nano scale catalysts

Paul Joseph Dyson, Zhaofu Fei, Ning Yan, Safak Bulut, Sviatlana Siankevich

In this article we highlight some of the recent developments in the aqueous-phase hydrogenation of alkenes and arenes. The traditional types of water-soluble catalysts applied in aqueous media are outlined together with recent trends towards the developmen ...

Free volume in ionic liquids: a connection of experimentally accessible observables from PALS and PVT experiments with the molecular structure from XRD data

Safak Bulut

In the current work, free volume concepts, primarily applied to glass formers in the literature, were transferred to ionic liquids (ILs). A series of 1-butyl-3-methylimidazolium (C4MIM) based ILs was investigated by Positron Annihilation Lifetime Spec ...
