Unlocking Thermodynamic‐Kinetic Synergy via Rh/Co Dual Sites and Ordered Interfacial Hydrogen‐Bond Network for Efficient Biomass Electrooxidation

Carbon Energy, EarlyView.
An amorphous RhOx‐decorated cobalt‐deficient Co3O4 catalyst is designed for efficient HMF electro‐oxidation to FDCA. This design enables Rh/Co dual sites for enhanced HMF/OH− adsorption thermodynamics while independently ordering interfacial water into a connected hydrogen‐bond network that accelerates proton transfer kinetics, delivering outstanding ...

Prey dynamics as a buffer: enhancing copepod resilience to ocean alkalinity enhancement

Environmental Research Letters
Abstract Ocean alkalinity enhancement (OAE) aims to counteract climate change by increasing the ocean’s carbon storage capacity through the addition of alkaline substances into seawater. However, this process alters seawater chemistry, increasing total alkalinity and pH, which can directly influence marine organisms’ metabolic activities

KOSMOS 2022 Bergen mesocosm study on ocean alkalinity enhancement: phytoplankton metabolic rates [PDF]

Ocean alkalinity enhancement (OAE) is a marine carbon dioxide removal (mCDR) with the potential to remove atmospheric CO2 and increase the ocean's buffering capacity. Thus, it may aid in mitigating global warming and ocean acidification. Depending on the

Novel field trial for ocean alkalinity enhancement using electrochemically derived aqueous alkalinity

Frontiers in Environmental Engineering
Ocean alkalinity enhancement is a proposed method of marine carbon dioxide removal that enhances the ocean’s uptake of atmospheric carbon dioxide (CO2) and converts it to dissolved bicarbonate for long-term ocean storage.

Selective Modification of the Product Profile of Biocatalytic Hydrolyzed PET via Product‐Specific Medium Engineering

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The product profile of enzymatically hydrolyzed PET can be modified by medium engineering and thereby adapted to a desired product. TPA, MHET or BHET can be forced as the predominant product using a basic pH (blue), 25 % ethylene glycol (EG) and IsPETasewt (green) or ≥25 % EG and LCCICCG (pink), respectively.

Achievement of Transition Metal Chalcogenides/Oxides in Hydrogen Production by Seawater Electrolysis

EcoEnergy, EarlyView.
Transition metal chalcogenides (TMCs)/oxides have shown great application potential in seawater splitting for hydrogen generation due to their adjustable electronic properties, abundant active sites, and excellent catalytic performance. ABSTRACT Under the impetus of global “dual carbon” goals, green hydrogen has become a key component of the future ...
