Highly efficient heterogeneous catalytic materials derived from metal-organic framework supports/precursors

Publication date: 15 April 2017
Source:Coordination Chemistry Reviews, Volume 337
Author(s): Shu-Na Zhao, Xue-Zhi Song, Shu-Yan Song, Hong-jie Zhang
Metal-organic frameworks (MOFs), as novel developing porous crystalline materials, are promising candidates in the field of heterogeneous catalysis because of their high surface area, diverse structures, low densities, adjusted pore sizes, etc. Recently, increasing attention has focused on developing MOF-supported/derived materials as heterogeneous catalysts. In this review, we present the recent development of MOFs as supports or precursors in the preparation of various functional nanomaterials for heterogeneous catalytic reactions including electrocatalysis, organocatalysis, and photocatalysis. Here, we present a comprehensive discussion on the recent progress and the rational design of MOF-supported or derived heterogeneous catalysts to provide insights into the future development of novel and highly efficient heterogeneous catalysts.

Manganese-Containing Periodic Mesoporous Organosilica with Ionic-Liquid Framework (Mn@PMO-IL): A Powerful, Durable, and Reusable Nanocatalyst for the Biginelli Reaction

by Dawood Elhamifar, Ahmad Shábani

Abstract

The catalytic application of a novel manganese-containing periodic mesoporous organosilica with ionic-liquid framework (Mn@PMO-IL) in the Biginelli reaction was investigated. First, the Mn@PMO-IL nanocatalyst was prepared and characterized by TEM, SEM, X-ray photoelectron spectroscopy, and nitrogen-sorption analysis. The catalyst was then used in the one-pot Biginelli condensation of various aldehydes with urea and alkyl acetoacetates under solvent-free conditions. The corresponding dihydropyrimidone products were obtained in high to excellent yields and selectivities at short reaction times. Moreover, the catalyst was recovered and successfully reused many times with no notable decrease in activity and selectivity.

Heterogeneous Biginelli catalyst: A manganese-containing periodic mesoporous organosilica with ionic-liquid framework (Mn@PMO-IL) was prepared, characterized, and used as a nanocatalyst in the Biginelli reaction. This catalyst showed excellent reactivity and selectivity in the Biginelli condensation of various aldehydes with urea and alkyl acetoacetates. Moreover, the catalyst could be recovered and reused at least 14 times with no decrease in activity and selectivity (see scheme).

Photobiocatalytic chemistry of oxidoreductases using water as the electron donor

by Maria Mifsud

Article

Enzymes have been considered as biocatalysts for organic chemistry, however their broad application has been somewhat hampered by the requirement for reducing cofactors. Here, the authors demonstrate that, in the presence of titania photocatalysts, water can be used as the sacrificial electron donor.

A selective and efficient electrocatalyst for carbon dioxide reduction

by Qi Lu

Article

Electrochemical reduction of carbon dioxide to more useful products is an industrially important process. Here, the authors report a nanoporous silver catalyst that efficiently and selectively reduces carbon dioxide due to its high surface area and intrinsically high activity.

Ruthenium-catalysed alkoxycarbonylation of alkenes with carbon dioxide

by Lipeng Wu

Article

The conversion of alkenes to esters is performed on a large scale worldwide, but relies on the use of toxic and flammable carbon monoxide. Here, the authors show a catalytic system where carbon dioxide—normally unreactive, but cheap and abundant—can be employed instead.

Article

Single-layered materials such as graphene are well known, but metallic elements tend to favour three-dimensional clusters. Here the authors report the synthesis of rhodium nanosheets—a supported, single-layered metallic material with rare δ-bonding.
