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.

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

Advanced Materials, EarlyView.Heterophase fcc‐hcp‐fcc RuFeMMnMo (M═CoNi, Co, and Ni) high‐entropy alloy nanomaterials have been successfully synthesized using a one‐pot approach. The highly random distribution of multiple metal components and the tunable diversity of metal atomic arrangements can be realized simultaneously. By combining metals with different work functions, fcc‐hcp‐

On‐Surface Synthesis of Bismuth Monolayers through Ice‐Confined Redox Reactions
Advanced Materials, EarlyView.We report an ice‐confined growth strategy for the synthesis of atomically thin 2D bismuth and related 2D metals. This approach involves rapid freezing of a BiCl3 aqueous solution on an aluminum foil using liquid nitrogen, which triggers interfacial redox reactions between the ice and the aluminum surface.

Spin‐Selective Anti‐Perovskite Enables Breakthrough Nitrate‐to‐Ammonia Electrocatalysis
Advanced Materials, EarlyView.CuNCo3 antiperovskite leverages built‐in 3d–3d interactions to stabilize and generate spin‐selective Co sites during nitrate reduction. Multiple operando techniques reveal that Cu acts as a promoter, inducing partial surface Co‐N cleavage and Cu‐Co charge redistribution.
