“…Both the catalytic and stability properties of the active copper phase can be greatly influenced by their chemical environment and/or the nature of the support [1][2][3][4][5]. We previously reported the preparation and properties of Ti-supported copper-doped cobalt oxide (Cu x Co 3-x O 4 ) electrodes [40,41].…”

Copper and copper oxides are well-known excellent catalysts in several chemical processes, but their low mechanical and electrochemical stability restrict their direct utilization as electrodes in electrolytic processes. In this work, the incorporation of copper into cobalt oxide (Cu x Co 3-x O 4 ) is presented as an excellent approach to obtain highly active and robust copper-based electrocatalysts. Particularly, the electrocatalytic performance of Ti-supported Cu x Co 3-x O 4 electrodes (with 0 ≤ x ≤ 1.5) has been studied for the oxidation of cyanide in alkaline media.Cyclic voltammetry and electrolysis runs show an outstanding effect of Cu on the activity, efficiency and kinetics of spinel Cu x Co 3-x O 4 electrodes for CN − electro-oxidation. Despite being active oxides with high activity towards water oxidation, copper saturated (x = 1.0) and oversaturated (x = 1.5) spinels exhibit unprecedented 100 % current efficiencies for the electrooxidation of CN − in aqueous electrolyte. In-situ surface enhanced Raman spectroscopy (SERS) reveals the specific adsorption of CN − ions on surface Cu species to be involved in the electrocatalytic oxidation mechanism. This electrocatalytic activity has been attributed to surface Cu(II) in the spinel lattice. Furthermore, the Cu x Co 3-x O 4 electrodes also display high

“…A special focus is given on the reaction modes for the CO 2 activation and its application as C1 building block in organic synthesis. While classical methods for CO 2 hydrogenation have been reviewed elsewhere and will not be included here [5][6][7] , the following subjects will be addressed: (1) novel transformations using carbon dioxide (briefly summarized in Fig. 1); (2) different reaction modes for CO 2 activation (main focus of this review); and (3) potential new applications of CO 2 valorization.…”

Using carbon dioxide as a building block in organic synthesis

et al. 2015

Carbon dioxide exits in the atmosphere and is produced by the combustion of fossil fuels, the fermentation of sugars and the respiration of all living organisms. An active goal in organic synthesis is to take this carbon-trapped in a waste product-and re-use it to build useful chemicals. Recent advances in organometallic chemistry and catalysis provide effective means for the chemical transformation of CO 2 and its incorporation into synthetic organic molecules under mild conditions. Such a use of carbon dioxide as a renewable one-carbon (C1) building block in organic synthesis could contribute to a more sustainable use of resources.A more sensible resource management is the prerequisite for the sustainable development of future generations. However, when dealing with the feedstock of the chemical industry, the level of sustainability is still far from satisfactory. Until now, the vast majority of carbon resources are based on crude oil, natural gas and coal. In addition to biomass, CO 2 offers the possibility to create a renewable carbon economy. Since pre-industrial times, the amount of CO 2 has steadily increased and nowadays CO 2 is a component of greenhouse gases, which are primarily responsible for the rise in atmospheric temperature and probably abnormal changes in the global climate. This increase in CO 2 concentration is largely due to the combustion of fossil fuels, which are required to meet the world's energy demand 1 . Obviously, there is an urgent need to control CO 2 emissions and develop efficient carbon capture systems. Although the extensive use of carbon dioxide for chemical production cannot solve this problem alone, CO 2 is a useful one-carbon (C1) building block in organic synthesis due to its abundance, availability, nontoxicity and recyclability. As a result, valorization of CO 2 is currently receiving considerable and ever increasing attention by the scientific community 2-4 . However, activation and utilization of CO 2 is still problematic due to the fact that it is the most oxidized form of carbon, which is also thermodynamically stable and/or kinetically inert in certain desired transformations. Consequently, most of the known studies used highly reactive substrates and/or severe reaction conditions to activate CO 2 , limiting the application of such methods. In particular, the catalytic coupling of CO 2 with energy-rich substrates, such as epoxides and aziridines, to generate polycarbonates/polycarbamates and/or cyclic carbonates/carbamates has drawn significant attention over the past decades. To create C-C bonds with CO 2 , the use of carbon nucleophiles is specifically limited to strong nucleophilic organolithiums and Grignard reagents, as well as phenolates.

Visible and Near‐Infrared Photothermal Catalyzed Hydrogenation of Gaseous CO₂ over Nanostructured Pd@Nb₂O₅

et al. 2016

The reverse water gas shift (RWGS) reaction driven by Nb2O5 nanorod‐supported Pd nanocrystals without external heating using visible and near infrared (NIR) light is demonstrated. By measuring the dependence of the RWGS reaction rates on the intensity and spectral power distribution of filtered light incident onto the nanostructured Pd@Nb2O5 catalyst, it is determined that the RWGS reaction is activated photothermally. That is the RWGS reaction is initiated by heat generated from thermalization of charge carriers in the Pd nanocrystals that are excited by interband and intraband absorption of visible and NIR light. Taking advantage of this photothermal effect, a visible and NIR responsive Pd@Nb2O5 hybrid catalyst that efficiently hydrogenates CO2 to CO at an impressive rate as high as 1.8 mmol gcat−1 h−1 is developed. The mechanism of this photothermal reaction involves H2 dissociation on Pd nanocrystals and subsequent spillover of H to the Nb2O5 nanorods whereupon adsorbed CO2 is hydrogenated to CO. This work represents a significant enhancement in our understanding of the underlying mechanism of photothermally driven CO2 reduction and will help guide the way toward the development of highly efficient catalysts that exploit the full solar spectrum to convert gas‐phase CO2 to valuable chemicals and fuels.
