“…The first synthesis of formates by hydrogenation reaction dates back to 1914 by Bredig and Carter using a Pd black catalyst under relatively mild conditions (70–95 °C, 30–60 bar of H 2 , 0–30 bar of CO 2 ). 46 The synthesis employed alkali/alkaline earth (bi)carbonates as the CO 2 source in the presence of H 2 (in some cases gaseous CO 2 was also added). In 1935 Farlow and Adkins reported the synthesis of formamides over Raney Ni through CO 2 hydrogenation at high pressure (400 bar) in the presence of primary and secondary amines in alcohol as solvent.…”

The recent advances in the development of heterogeneous catalysts and processes for the direct hydrogenation of CO2 to formate/formic acid, methanol, and dimethyl ether are thoroughly reviewed, with special emphasis on thermodynamics and catalyst design considerations. After introducing the main motivation for the development of such processes, we first summarize the most important aspects of CO2 capture and green routes to produce H2. Once the scene in terms of feedstocks is introduced, we carefully summarize the state of the art in the development of heterogeneous catalysts for these important hydrogenation reactions. Finally, in an attempt to give an order of magnitude regarding CO2 valorization, we critically assess economical aspects of the production of methanol and DME and outline future research and development directions.

“…Among these, FA is an attractive product that can be easily generated via CO 2 hydrogenation reaction, which exhibits wide applications in leather tanning, silage preservation and hydrogen storage [21–23] . Many efforts have been devoted to produce FA with heterogeneous catalysts and Pd‐based catalysts are found to be the most promising [24–47] . The first reported Pd‐based heterogeneous catalyst was Pd black, found by Bredig and Carter in 1914 [35] .…”

Zinc Oxide Morphology‐Dependent Pd/ZnO Catalysis in Base‐Free CO₂ Hydrogenation into Formic Acid

Pd/ZnO catalysts with ca. 2 wt.% Pd loading employing ZnO nanocrystals with various morphologies as supports, including ZnO nanoplates (p−ZnO) predominantly exposing polar {002} facets, ZnO nanorods (r−ZnO) predominantly exposing nonpolar {100} and {101} facets, and commercial ZnO (c−ZnO) exposing random facets, have been prepared as catalysts for the catalytic reaction of CO2 hydrogenation into formic acid (FA) without the addition of base under mild conditions. A remarkable morphology‐dependence of zinc oxide in the Pd/ZnO catalysts was observed. Catalytic activities of various Pd/ZnO catalysts in CO2 hydrogenation into FA follow an order of Pd/r−ZnO>Pd/p−ZnO>Pd/c−ZnO, and all the catalysts are stable. Kinetic study, CO2‐TPD analysis, and in situ DRIFTS spectra provide evidence that all the Pd/ZnO catalysts follow a similar catalytic mechanism that CO2 activation is the rate‐determining step. Consequently, r−ZnO, possessing a higher density of weak basic sites than p−ZnO and c−ZnO, can act as a superb support to prepare Pd/r−ZnO catalyst, which is more active than Pd/p−ZnO and Pd/c−ZnO catalysts for the production of FA. These findings nicely demonstrate the crystal‐plane engineering of the metal oxide support in tuning the catalytic performance of Pd‐based catalysts for CO2 hydrogenation into FA.

“…The first example of FA synthesis from CO 2 and H 2 was reported in 1914 by Brediga nd Carter, who demonstrated the possibility of catalytic hydrogenation of CO 2 and aqueous alkali carbonates to FA under mild conditions in the presenceo f bulk Pd. [16] After approximately 100 years from these initial observations, ac atalystf ormulation of the 21st centuryt hat also utilised Pd as the key component has been reported. Bi et al have recently described ah ighly active system for reversible CO 2 hydrogenation based on ar educed graphene oxide supported Pd catalyst.…”

A DFT Study of CO₂ Hydrogenation on Faujasite‐Supported Ir₄ Clusters: on the Role of Water for Selectivity Control

et al. 2016

Reaction mechanisms for the catalytic hydrogenation of CO2 by faujasite‐supported Ir4 clusters were studied by periodic DFT calculations. The reaction can proceed through two alternative paths. The thermodynamically favoured path results in the reduction of CO2 to CO, whereas the other, kinetically preferred channel involves CO2 hydrogenation to formic acid under water‐free conditions. Both paths are promoted by catalytic amounts of water confined inside the zeolite micropores with a stronger promotion effect for the reduction path. Co‐adsorbed water facilitates the cooperation between the zeolite Brønsted acid sites and Ir4 cluster by opening low‐energy reaction channels for CO2 conversion.
