Sustainable Chemistry

The presidents of the chemical societies of France (SFC), Germany (GDCh), Japan (CSJ), the Netherlands (KNCV), the UK (RSC), and the USA (ACS) recently pledged on behalf of about 300,000 members to "work together to promote global sustainable development, demand responsible use of resources, and ensure that the next generation of scientists protects and maintains the well-being of Earth and its inhabitants." They deem this issue an urgent one, and that chemistry is absolutely essential to the development of solutions.

Concerning the Role of Supercritical Carbon Dioxide in SN1 Reactions

Not super here: Supercritical CO2 as a solvent does not activate alkyl halides by SN1-type ionization for alkylation reactions as recently claimed.

Strategies for Enhancing the Catalytic Performance of Metal–Organic Frameworks in the Fixation of CO2 into Cyclic Carbonates

Strategies for Enhancing the Catalytic Performance of Metal–Organic Frameworks in the Fixation of CO2 into Cyclic Carbonates

A stable MOF: The metal–organic framework MIL-100(Cr) is presented as a promising new heterogeneous catalyst with high activity, selectivity and reusability in the solvent-free synthesis of styrene carbonate from CO2 at mild conditions. Two strategies to increase the reusability of the MOF catalysts are proposed.

Decarboxylative Giese-Type Reaction of Carboxylic Acids Promoted by Visible Light: A Sustainable and Photoredox-Neutral Protocol

Decarboxylative Giese‐Type Reaction of Carboxylic Acids Promoted by Visible Light: A Sustainable and Photoredox‐Neutral Protocol

The decarboxylative alkylation of carboxylic acids can be efficiently promoted by visible light under air at room temperature by using 9-mesitylene-10-methylacridinium perchlorate ([Acr-Mes]ClO4) as photocatalyst. A range of readily available starting materials are well tolerated in this transition-metal-free protocol.

Integrating Reverse-Electrodialysis Stacks with Flow Batteries for Improved Energy Recovery from Salinity Gradients and Energy Storage

Integrating Reverse‐Electrodialysis Stacks with Flow Batteries for Improved Energy Recovery from Salinity Gradients and Energy Storage

Salinity gradient energy recovery: The environmentally friendly 2,6-dihydroxyanthraquinone (2,6-DHAQ) and ferrocyanide redox couples are used to integrate reverse electrodialysis stacks and flow batteries, called RED-FB systems, for the efficient capture, storage, and discharge of salinity gradient energy. The maximum power density reaches 3.0 kW m−2-anode and the energy density is 2.4 kWh m−3-anolyte, with an energy efficiency of 30 %.
