Abstract

To develop high-performance metal-organic frameworks (MOFs) for catalysis is of great importance. Here, we synthesized the mesoporous Cu3−xZnx(BTC)2 (BTC = benzene-1,3,5-tricarboxylate) nanocubes in a deep eutectic solvent of ZnCl2/ethylene glycol solution. The route can proceed at room temperature and the reaction time needed is shortened to be 30 min, which is superior to the conventional solvothermal route that usually needs high temperature and long reaction time. The formation mechanism of the mesoporous Cu3−xZnx(BTC)2 nanocubes in deep eutectic solvent (DES) was investigated by in situ synchrotron X-ray diffraction/small angle X-ray scattering/X-ray absorption fine structure conjunction technique. The mesoporous Cu3−xZnx(BTC)2 nanocubes exhibit high catalytic activity and reusability for cyanosilylation reaction of benzaldehyde and aerobic oxidation reaction of benzylic alcohol.

Abstract

To produce metal-organic framework (MOF) catalysts with both high activity and durability is interesting but challenging. We report an amorphous MOF (NH2-MIL-68), which combines the advantages of (1) a large number of open metal sites, (2) the basic building blocks and connectivity of crystalline NH2-MIL-68, and (3) hierarchically meso- and microporous structure. It exhibits high performances in electrocatalytic reduction of CO2 and photochemical cycloaddition of CO2 under mild conditions. For the former reaction, the maximum Faradaic efficiency for product formic acid (FEHCOOH) reaches 93.3% with a current density of 34.2 mA·cm−2 at −2.05 V vs. Ag/Ag+ catalyzed by amorphous NH2-MIL-68, while the crystalline NH2-MIL-68 shows FEHCOOH of 67.7% with considerable productions of CO and H2 at the same experimental conditions. For the photochemical cycloaddition of CO2 with styrene oxide, the yield by amorphous NH2-MIL-68 can reach 94.1% at 12 h, which is higher than the reported value under similar conditions. The structure—efficiency relationship of the catalyst for the two reactions was investigated. This work opens up new possibility for designing high-performance MOF and MOF-based catalysts.

Abstract

Coordination polymers (CPs) display great potential for the development of highly active photocatalysts. Herein, we report the fabrication of a highly crystalline CP, [Ag2BTT]n (BTT=benzene‐1,2,4,5‐tetrathiol). The crystal structure of [Ag2BTT]n was resolved and its performance for photocatalytic oxidation of thioanisole was explored. [Ag2BTT]n is highly active and selective for the photo‐oxidation of sulfides to sulfoxides under mild conditions, that is, in air, at room temperature and in the absence of a sacrificial reagent, co‐catalyst or redox mediator.

37. Anchoring Ionic Liquid in Copper Electrocatalyst for Improving CO2 Conversion to Ethylene.

Abstract

Electrochemical conversion of CO2 to valuable fuels is appealing for CO2 fixation and energy storage. The Cu‐based catalysts feature unique superiorities, but achieving high ethylene selectivity is still restricted. In this study, we propose the anchoring of an ionic liquid (IL) on a Cu electrocatalyst for improving the electrochemical CO2 reduction to ethylene. In a water‐based electrolyte and a commonly used H‐type cell, a high ethylene Faradaic efficiency of 77.3 % was achieved at −1.49 V (vs. RHE). Experimental and theoretical studies reveal that an IL can modify the electronic structure of a Cu catalyst through its interaction with Cu, making it more conducive to *CO dimerization for ethylene formation.
