Correlated Dual‐Gradient Electrodes Enabling Spatially Synchronized Sulfur Redox in High‐Mass‐Loading Li–S Batteries Under High Current Densities

Advanced Materials, EarlyView.
Coupling a dual‐gradient carbonized framework with Fe2O3/Fe‐N‐C catalytic sites enables spatially synchronized sulfur redox across the entire electrode thickness in high‐mass‐loading Li–S batteries. This synergistic structural–catalytic design effectively mitigates concentration, ohmic, and electrochemical polarization, thereby achieving high‐capacity ...

Maximize the Electrocatalytic Activity of Pt Toward Ethanol Oxidation via Engineering PdPt1 Single‐Atom Alloy Skin

Advanced Materials, EarlyView.
Maximizing atomic utilization of Pt is crucial for efficient electrocatalysis. We constructed a tensile‐strained PdPt1 single‐atom alloy (SAA) skin by implanting atomically dispersed Pt onto the surface of intermetallic Pd5Bi3 core‐ultrathin Pd shell octahedrons, fully exposing active Pt atoms to boost ethanol oxidation electrocatalysis.

Hexanuclear nickel-added silicotungstates as high-efficiency electrocatalysts for nitrate reduction to ammonia

Polyoxometalates
Ammonia (NH3) is widely used in a wide range of fields because of its high energy density, and NH3 is simple to liquefy and transport. Nitrate is also a source of pollution of the environment and drinking water sources.

Energy‐Efficient, Sustainable Cascade Glucose Electrooxidation into Glucaric Acid

Advanced Materials, EarlyView.
This study presents a tandem system that efficiently converts glucose into glucaric acid while generating renewable electricity. By decoupling the oxidation process into two cascaded steps, the system achieves an overall 90% Faradaic efficiency and 80% conversion efficiency at ∼0.6 VRHE, significantly reducing energy consumption compared to traditional
