Incompatibility between organic electrodes and inorganic solid electrolytes limits the performance of solid-state organic batteries. Here, the authors introduce indigo natural dye as a redox-active material and molecular catalyst, enabling high capacity and long cycle life via synergistic redox reactions with sulfide electrolytes.

Ethanol electrosynthesis from CO reduction is achieved using an oxygen-affinity-engineered copper alloy catalyst. Unlike conventional CO dimerization pathways, which yield diverse products, this catalyst selectively promotes the CO–CH_x coupling route, enabling selective ethanol production.

Organic electrode materials offer a versatile and sustainable route for lithium-ion batteries, but their application is hindered by low working voltages and poor cycling stability. Now, it has been shown that dissolving halide electrolytes into organic electrodes effectively tunes the working voltage and enhances the electrochemical performance of all-solid-state batteries.

Integrating electrochemical CO electrolysers with a bioreactor can yield high-value long-chain carbon products, but the electrolytes for the two systems are mismatched. Now, a porous solid electrolyte reactor, which can produce acetate directly in bioelectrolyte, is demonstrated. Direct integration with a bioreactor produces bioplastic from CO via the acetate intermediate.

While the high concentration of CO₂ in flue gas makes it an attractive feedstock for electrocatalytic production of useful molecules, SO₂ contaminants can poison catalysts. Here the authors report a polymer/catalyst/ionomer heterojunction design with hydrophobic and hydrophilic domains that improves the SO₂ tolerance of a Cu catalyst.

A study using a copper-in-silver dilute alloy catalyst in a high-pressure gas flow reactor reports highly selective electrosynthesis of acetate from carbon monoxide.

By combining O₂/H₂O redox electrolysis with a modular solid-electrolyte reactor, a design for continuous electrochemical carbon capture showing high capture rates, high Faradaic efficiencies and low energy consumption is demonstrated.

Despite the natural abundance and promising properties of Si, there are few examples of crystalline Si-based catalysts. Here, the authors report an epitaxial growth method to construct Co single atoms on Si for light driven CO2 reduction to syngas.

Developing amorphous solid electrolytes for solid state lithium batteries is challenging due to limited understanding of disordered structures. Here, the authors report a family of oxychloride amorphous solid electrolytes with high ionic conductivities and promising electrochemical characteristics.

The performance of single atom catalysts (SACs) is controlled by the metal single atom sites, but the role of the matrix material is less understood. Now, a hard-template synthesis is reported, enabling control of the atomic and mesoporous structures of SACs and the probing of matrix materials with either 2D or 3D diffusion channels.

Transition-metal single-atom catalysts display excellent activity per metal atom site, but suffer from low metal atom densities (typically less than 5 wt% or 1 at.%), which limits their overall catalytic performance. Now, the use of a graphene-quantum-dot primary support, later interweaved into a carbon matrix, has enabled the synthesis of single-atom catalysts with high transition-metal atom loadings of up to 40 wt% or 3.84 at.%.

Developing green and delocalized routes for ammonia synthesis is highly important but still very challenging. Here the authors report an efficient ammonia synthesis process via nitrate reduction to ammonia on Fe single atom catalyst.

While acidic water splitting offers a renewable means to obtain renewable hydrogen fuel, the catalysts needed to oxidize water often require expensive noble metals. Here, authors show manganese oxyhalides as acidic oxygen evolution electrocatalysts.
