Contrasting carbon dioxide removal potential and nutrient feedbacks of simulated ocean alkalinity enhancement and macroalgae afforestation

Environmental Research Letters, 2023
Alongside cuts to emissions, hundreds of gigatons of carbon dioxide removal (CDR) are likely to be required to limit global warming to below 1.5 °C or 2 °C this century.

Fe Atoms Accelerator Coupled With Oxygen Vacancies Channel Synergistically Boost OER Performance of Fe‐CoMoO4‐Ov Nanosheets

Carbon Energy, EarlyView.
Fe‐CoMoO4‐Ov/NF demonstrates significantly improved OER catalytic performance compared to CoMoO4. Specifically, the introduced Fe atoms act as a promoter for surface reconstruction, significantly reducing the energy required for surface reconstruction to generate FeCoOOH. The oxygen vacancies serve as electron channels between the core Fe‐CoMoO4‐Ov and

Assessing the technical aspects of ocean-alkalinity-enhancement approaches

State of the Planet, 2023
Abstract. Ocean alkalinity enhancement (OAE) is an emerging strategy that aims to mitigate climate change by increasing the alkalinity of seawater. This approach involves increasing the alkalinity of the ocean to enhance its capacity to absorb and store carbon dioxide (CO2) from the atmosphere. This chapter presents an overview of the technical aspects

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 ...

B, N‐Co Doped Porous Carbon Nanotubes Supported Cu Single Atoms and B‐Doped Cu Nanoparticles for High‐Performance Electrocatalytic NO3RR and Zn‐Nitrate Batteries

Carbon Energy, EarlyView.
The ToC image shows a porous B, N‐doped carbon nanotube decorated with B‐doped Cu nanoparticles for nitrate‐to‐ammonia conversion. The unique structure enhances charge transport, promotes the adsorption and activation of key intermediates, alters the rate‐determining step, suppresses hydrogen evolution, and improves NH3 yield and Faradaic efficiency ...

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.

The Critical Role of Economies of Scale: A Techno‐Economic Assessment of Small‐ Versus Large‐Scale Biogas Upgrading in Rural Tanzania

Energy Science &Engineering, EarlyView.
Small‐scale biogas upgrading can improve methane quality but remains financially unattractive to individual rural households. Community‐scale implementation substantially lowers energy costs, demonstrating that economies of scale are critical to making purified biogas a viable clean‐cooking option in Tanzania.
