“…Nowadays, a number of technological approaches, such as electrochemical, photochemical, biochemical, and thermochemical technologies, or a smart combination of them, have been exploited to realize the catalytic conversion of CO 2 . Among them, photochemical transformation of CO 2 requires the use of metal complexes with poor stability as catalysts and sacrificial electron donors to supply electrons for the reduction process, which are both highly challenging.…”

The selective electrochemical CO2 reduction (ECR) to CO in aqueous electrolytes has gained significant interest in recent years due to its capability to mitigate the environmental issues associated with CO2 emission and to convert renewable energy such as wind and solar power into chemical energy as well as its potential to realize the commercial use of CO2. In view of the thermodynamic stability and kinetic inertness of CO2 molecules, the exploitation of active, selective, and stable catalysts for the ECR to CO is crucial to promote the reaction efficiency. Indeed, plenty of electrocatalysts for the selective ECR to CO have been explored, of which Ag is known as the most promising electrocatalyst for large‐scale ECR to CO due to several competitive advantages including high catalytic performance, low price, and rich reserves compared with other metal counterparts. To provide useful guidelines for the further development of efficient catalysts for the ECR to CO, a comprehensive summary of the recent progress of Ag‐based electrocatalysts is presented in this Review. Different modification strategies of Ag‐based electrocatalysts are highlighted, including exposure of crystal facets, tuning of morphology and size, introduction of support materials, alloying with other metals, and surface modification with functional groups. The reaction mechanisms involved in these different modification strategies of Ag‐based electrocatalysts are also discussed. Finally, the prospects for the development of next‐generation Ag‐based electrocatalysts are proposed in an effort to facilitate the industrialization of ECR to CO.

“…The authors suggest a key role could be played at this stage by the oxygen donor atom of Xantphos ligand as its coordination to Co would assist the tautomerization of η 3 -allyl-Co to η 1 -allyl-Co complex (Scheme 13b). Reductive elimination of CH 4 from η 1 -allyl-Co(H)(CH 3 ) intermediate (13) leads to a low valent allyl-Co complex (14) able to undergo electrophilic attack from CO 2 at the γ-position. The last stage involves transmetallation between the carboxylated-Co complex (15) and AlMe 3 regenerating the L n Co(I)Me catalyst and producing R-COOAlMe 2 .…”

“…The high thermal and kinetic stability of the CO 2 molecule require for a suitable catalyst and energy input when employed in E-CO 2 bond formation (E = O, N, C) or reduction reactions. Current synthetic options for CO 2 -fixation into useful chemicals encompasses chemical, electro-chemical, photo-chemical, photo-electrochemical and biological approach that have been overviewed in a number of excellent books and comprehensive reviews [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”

This review focuses on recent advances in the field of direct carboxylation reactions of C(sp 3 )-H and C(sp 2 )-H bonds using CO 2 encompassing both transition-metal-catalysis and base-mediated approach. The review is not intended to be comprehensive, but aims to analyze representative examples from the literature, including transition-metal catalyzed carboxylation of benzylic and allylic C(sp 3 )-H functionalities using CO 2 which is at a "nascent stage". Examples of light-driven carboxylation reactions of unactivated C(sp 3 )-H bonds are also considered. Concerning C(sp 3 )-H and C(sp 2 )-H deprotonation reactions mediated by bases with subsequent carboxylation of the carbon nucleophile, few examples of catalytic processes are reported in the literature. In spite of this, several examples of base-promoted reactions integrating "base recycling" or "base regeneration (through electrosynthesis)" steps have been reported. Representative examples of synthetically efficient, base-promoted processes are included in the review.

Thermo‐Photocatalysis: Environmental and Energy Applications

Catalysis is an integral part of a majority of chemical operations focused on the generation of value‐added chemicals or fuels. Similarly, the extensive use of fossil‐derived fuels and chemicals has led to deterioration of the environment. Catalysis currently plays a key role in mitigating such effects. Thermal catalysis and photocatalysis are two well‐known catalytic approaches that were applied in both energy and environmental fields. Thermo‐photocatalysis can be understood as a synergistic effect of the two catalytic processes with key importance in the use of solar energy as thermal and light source. This Review provides an update on relevant contributions about thermo‐photocatalytic systems for environmental and energy applications. The reported activity data are compared with the conventional photocatalytic approach and the base of the photothermal effect is analyzed. Some of the systems based on the positive aspects of thermo‐ and photocatalysis could be the answer to the energy and environmental crisis when taking into account the outstanding results with regard to chemical efficiency and energy saving.
