Electrocatalytic CN Coupling: Advances in Urea Synthesis and Opportunities for Alternative Products

open access: yesChemSusChem, EarlyView.
This review explores electrocatalytic urea synthesis via carbon–nitrogen (CN) coupling from CO2 and nitrogen species, specifically nitrate, nitrite, nitric oxide, and nitrogen gas. It discusses recent discoveries in catalyst design, reaction pathways, and detection methods. Future outlooks on industrial applications, alternative CN coupling products,

Rethinking Chlorine: Essential Chemical or Replaceable Risk?

open access: yesChemSusChem, EarlyView.
Chlorine is essential for the production of plastics and pharmaceuticals but poses significant safety and environmental risks. Herein, processes are presented that substitute chlorine or reduce its demand. Where indispensable, trichloride‐ and bichloride‐based ionic liquids could enhance safety and streamline the integration of renewable energy ...

Scope and Limitations of the Use of Methanesulfonic Acid (MSA) as a Green Acid for Global Deprotection in Solid‐Phase Peptide Synthesis

open access: yesChemSusChem, EarlyView.
TFA is the only acid used for the cleavage of peptides from the resin. However, this acid belongs to the PFAS family, which is anticipated to face usage restrictions. Herein, the use of MSA, which is a “Natural Green Acid” is proposed to substitute TFA for the global deprotection and cleavage in SPPS.

Recycling of Polyurethane via Mechanocatalytic Methanolysis/Hydrolysis

open access: yesChemSusChem, EarlyView.
In this study, it is shown that up to 86% of soluble polyol can be recovered from the hydrolysis of polyurethane using a ball milling‐assisted process below 100 °C in the presence of NaOH, a small amount of H2O and a Cu/MgAlOx co‐catalyst. Polyurethane (PU) is the 6th most produced plastic on a global basis, and thus one of the most important targets ...

A Roadmap for Biomass‐Driven Development of Sustainable Phase Change Materials

open access: yesChemSusChem, EarlyView.
This comprehensive review advances the scientific understanding of sustainability and circularity in phase change material (PCM) fabrication by providing a strategic framework for developing composites from abundant, renewable resources. By screening biomass‐derived PCMs, carbons, and biopolymers, a roadmap is outlined for the development of ...

Mechanochemical Activation of NaHCO3: a Solid CO2 Surrogate in Carboxylation Reactions

open access: yesChemSusChem, Accepted Article.
Carbon dioxide, a primary driver of global warming, offers a promising feedstock for valuable chemical synthesis. Nonetheless, the reliance on highly pressurized canisters and specialized equipment limits its practical application in fine chemical synthesis.
