Cyclometalation of lanthanum(iii) based MOF for catalytic hydrogenation of carbon dioxide to formate

Abstract

A novel metal–organic framework JMS-1 with rare topology zaz shows catalytic activity towards conversion of carbon dioxide to formate.

A unified topology approach to dot-, rod-, and sheet-MOFs

“…15 However, rod-MOFs, and now sheet-MOFs, pose a particular problem because these are commonly analyzed in a different way from dot-MOFs. 2,16,17 A unified approach would be advantageous both from a synthesis and an understanding perspective. Note, however, we do not in any way seek to supersede or diminish current efforts to generate solid algorithms for the automatic analysis of the large amount of crystallographic data now available 18,19 ; we find these absolutely essential.…”

“…Making connections only through the organic ligand does not consider the rod at all (see standard method, Figure 7, left). Recently, alternative approaches to rod-MOFs have been discussed, 16,17 and we will also compare them with a simplified version of the straight rod representation (STR) (Figure 7 center right). We also note the method recently proposed to use both points of extension and metal centers (PE&M, Figure 7 right).…”

Rare‐Earth‐Based Metal–Organic Frameworks as Multifunctional Platforms for Catalytic Conversion

“…For the reduction of greenhouse gas CO 2 , Mehlana's group prepared a La-based MOF catalyst functionalized by bivalent Ru for CO 2 conversion under optimized conditions (pressure of 50 bar and temperature of 110 °C). [98] The product was high-yield (98%) formate in the presence of hydrogen. In addition, the CO 2 can also be converted to organic products by cycloaddition process detailed in chapter 4.…”

“…hydrogenation of CO 2 to form formate. [98] Moreover, the catalytic activity of La-based MOF was enhanced by adding bivalent Ru sites. In addition, El-Shall and co-workers [121] reported an excellent catalyst support consisting of Ce-based MOF and partially reduced graphene oxide.…”

Recent progress in materials development for CO2conversion: issues and challenges

“…241 Tshuma et al also prepared efficient lanthanum (La)-based MOFs for catalytic hydrogenation of CO 2 to formate under optimized reaction conditions. 242 Several homogeneous catalysts containing porphyrin/salen sites show high activity under harsh reaction conditions, which may be insignificant for an economical process. 243 Nevertheless, MOF-based catalysts hold inherent advantages of having vacant/partially coordinated metal ions that can be readily available as the Lewis acid site for the activation of epoxides.…”
