The Effect of Water Management and Cell Compression in Bipolar Membrane CO2 Electrolysis to CO

open access: yesCarbon Energy, EarlyView.
In‐operando neutron imaging uncovers water management challenges in bipolar membrane CO2 electrolysis: Internal water generation floods the cathode, while compression dictates membrane and gas diffusion electrode integrity. Strategic adjustments are applied in this work: dry gas feed and mechanical support of the gas diffusion electrode enable stable ...

Regulating Interfacial Water Structure on CoNi/MoN Heterostructures Boosts Electrocatalytic Nitrate Reduction to Ammonia

open access: yesCarbon Energy, EarlyView.
The CoNi/MoN interface effect induces electron transfer from CoNi species to MoN nanosheets, in which electron‐enriched CoNi/MoN interface captures K+ to form K+‐H2O, facilitating H2O dissociation to provide *H for accelerating hydrogenation steps, while electron‐deficient CoNi nanoparticles enhances the NO3− adsorption and reduces the free energy ...

Dual‐Function Electrocatalysis: Simultaneous Wastewater Remediation and Hydrogen Evolution—A Comprehensive Review

open access: yesCarbon Energy, EarlyView.
Replacing the oxygen evolution reaction with the electro‐oxidation of pollutants and waste streams offers an energy‐efficient route for simultaneous hydrogen production and pollutant remediation. This review summarizes the reaction mechanisms, catalyst design principles, and emerging paired‐electrolysis strategies that govern activity, selectivity ...

Applications of Biomaterials in Separators for Secondary Batteries

open access: yesCarbon Energy, EarlyView.
In this review, biomaterial‐based separators are reviewed as sustainable alternatives to conventional polyolefin‐based separators. For 12 different natural polymers, spanning from Protista, Plantae, and Animalia, viable strategies for synthesizing biomass‐based separators are described.

Regio‐Selective Electrocatalysis in Single‐Wall Carbon Nanotubes: Platinum Inside for Hydrogen Evolution Reaction/Hydrogen Oxidation Reaction and Ruthenium Outside for Oxygen Evolution Reaction

open access: yesCarbon Energy, EarlyView.
A Pt‐in/Ru‐out single‐wall carbon nanotube architecture spatially separates HER/HOR and OER active sites, enabling high HER/HOR currents at low overpotential, durable OER activity, and strong resistance to Fe3+ poisoning, offering a promising bifunctional platform for unitized regenerative fuel cells.
