Carbon Dioxide

CO2 emission causes many environmental problems. To mitigate the concentration of CO2 in the atmosphere, the fixation, activation, and capture of CO2 through chemical reactions is important. Increasingly, CO2 is used as a carbon source in syntheses.

Hydrogenation of Carbon Dioxide over K-Promoted FeCo Bimetallic Catalysts Prepared from Mixed Metal Oxalates

Hydrogenation of Carbon Dioxide over K‐Promoted FeCo Bimetallic Catalysts Prepared from Mixed Metal Oxalates

Promoting effect of potassium: In the hydrogenation of CO2 over K-promoted FeCo bimetallic catalysts, initial CO2 conversion was dependent on K loading, whereas most catalysts exhibited similar conversion levels after a few hours. Decarburization suggests that potassium stabilizes iron carbides and decreases the hydrogenation function of the catalysts; thus, it controls product selectivity. Potassium enhanced acetic acid formation and suppressed ethanol production.

A Sodium-Ion-Conducting Direct Formate Fuel Cell: Generating Electricity and Producing Base

A Sodium‐Ion‐Conducting Direct Formate Fuel Cell: Generating Electricity and Producing Base

Electrochemical energy conversion: A Na+-conducting direct formate fuel cell (Na-DFFC) was successfully developed and operated without adding OH and Na+ ions. Contrary to the conventional chlor-alkali process, the Na-DFFC enables to generate electricity and produce base simultaneously without polluting the environment.

Decisive Intermediates Responsible for the Carbonaceous Products of CO2 Electro-reduction on Nitrogen-Doped sp2 Nanocarbon Catalysts in NaHCO3 Aqueous Electrolyte

Decisive Intermediates Responsible for the Carbonaceous Products of CO2 Electro‐reduction on Nitrogen‐Doped sp2 Nanocarbon Catalysts in NaHCO3 Aqueous Electrolyte

The penny drops: The reaction mechanism on nitrogen-doped sp2 nanocarbon materials is resolved by clarifying the authentic origin of the carbonaceous products: CO and HCO2. Two carbon-reduction pathways are identified: a dominant pathway leading to CO from CO2 and a secondary pathway leading to HCO2 from HCO3. Neither hydrocarbon (CxHy) nor alcohol or aldehyde (CxHyOz) were detected in the reduction of CO2.

Construction of Well-Defined Redox-Responsive CO2-Based Polycarbonates: Combination of Immortal Copolymerization and Prereaction Approach

Construction of Well‐Defined Redox‐Responsive CO2‐Based Polycarbonates: Combination of Immortal Copolymerization and Prereaction Approach

By specific control, starter-based redox-responsive polycarbonates from CO2 and epoxides are reported by combination of immortal polymerization and prereaction approach. Via judicious use of 3,3′-dithiodipropionic acid as starter, the initiating group of traditional binary catalyst system is completely suppressed, resulting in pure starter-initiated polymer. The polymer is liable under reducing conditions and can be further modified by cross metathesis.

Photochemical Carboxylation of Activated C(sp3)−H Bonds with CO2

Photochemical Carboxylation of Activated C(sp3)−H Bonds with CO2

From ugly duckling to beautiful C1: Although CO2 may represent an ideal C1 source, it is challenging to use it as a raw material and direct carboxylation with CO2 has mainly been confined to highly reactive species. However, recent significant breakthroughs have been made in photochemical carboxylation of challenging, un-acidic, C(sp3)−H bonds, including benzylic, allylic and amine C−H bonds.

A Simple Zinc Catalyst for Carbamate Synthesis Directly from CO2

A Simple Zinc Catalyst for Carbamate Synthesis Directly from CO2

Zinc rocks: A new method for synthesizing carbamates directly from amines and CO2 was developed. A commercially available zinc compound was used as the catalyst, and the addition of an N-donor ligand increased the yield to 96 % (isolated product). Both aliphatic and aromatic amines could be activated, and thus the utility of this reaction in organic synthesis and the polyurethane industry is broad.

Screening the Effect of Water Vapour on Gas Adsorption Performance: Application to CO2 Capture from Flue Gas in Metal–Organic Frameworks

Screening the Effect of Water Vapour on Gas Adsorption Performance: Application to CO2 Capture from Flue Gas in Metal–Organic Frameworks

Capturing MOFs: A simple screening strategy is proposed to follow the CO2 adsorption behaviour of 45 metal– organic frameworks (MOFs) that are pre-equilibrated with varying amounts of H2O. Different behaviours are observed and discussed, ranging from large decreases in CO2 uptake with degree of wetting to a negligible influence of water. Materials showing promising CO2 uptake are highlighted as of interest for further studies.

Supercritical CO2-Assisted Reverse-Micelle-Induced Solution-Phase Fabrication of Two-Dimensional Metallic 1T-MoS2 and 1T-WS2

Supercritical CO2‐Assisted Reverse‐Micelle‐Induced Solution‐Phase Fabrication of Two‐Dimensional Metallic 1T‐MoS2 and 1T‐WS2

Supercritical CO2-assisted reverse-micelle-induced phase engineering can form strained 2D single-layers, which directly contributes to the successful transformation of 2H- to 1T-phase MS2. The obtained 1T-MoS2 exhibits good activity for the hydrogen evolution reaction in comparison with 2H-MoS2.

Ion-Conductive Properties of a Polymer Electrolyte Based on Ethylene Carbonate/Ethylene Oxide Random Copolymer

Ion‐Conductive Properties of a Polymer Electrolyte Based on Ethylene Carbonate/Ethylene Oxide Random Copolymer

A random copolymer of ethylene oxide with CO2 , namely, poly(ethylene carbonate/ethylene oxide) (P(EC/EO)), has been synthesized as a novel candidate for polymer electrolytes. Electrolyte composed of P(EC/EO) and lithium bis(fluorosulfonyl)imide is promising material for use in all-solid-state batteries because of its very high Li+ conductivity.
