Advanced Science, EarlyView.Crystalline@amorphous core–shell PdCN‐P nanocubes exhibit outstanding catalytic performance for formic acid oxidation, with mass activity and specific activity reaching 2.503 A mg−1Pd and 6.497 mA cm−2, respectively. Detailed theoretical and experimental analyses indicate that the unique core‐shell architecture can increase surface active sites, lower ...

Advanced Science, EarlyView.At alkaline conditions (pH = 13), for FePPc and Pz‐FeTPr at low potential (less than 0.5 V), the ORR mechanism is the *O2 mechanism (O2→∗O2→∗OOH→∗O→∗OH→H2O${{\rm{O}}_2} \to ^*{O_2} \to ^*OOH \to ^*O \to ^*OH \to {H_2}O$), Fe is the active site; for Pz‐FeTPr at high potential (larger than 0.5 V), the Fe site is covered by O2−$O_2^ - $, the nearby C site

Advanced Science, EarlyView.In this work, a series of porous carbon spheres with tunable pore size, particle size, and shell thickness are designed as nanoreactors for the S‐ZnS redox reactions in Zn‐S batteries. The presence of abundant defects and oxygen‐containing functional groups facilitates efficient ion/electron transport throughout the reaction process, significantly ...

Advanced Science, EarlyView.A ligand regulation strategy by modifying functional motifs (X = −NH2, −OH, and −SH) in triphenylene is pioneered and developed to afford Cu─X bonds, achieving a synergistic conduction and polarisation loss mechanism under an electromagnetic field for enhanced electromagnetic wave absorption. Abstract Conduction and polarization are known to profoundly

Advanced Energy Materials, EarlyView.FeMn(NbTa)2O6‐columbite is a sustainable and high‐performance bifunctional electrocatalyst for anion exchange membrane water electrolyzers, comparable to benchmark catalysts. In situ XAS and DFT analysis show Fe/Mn sites exhibit higher OER activity due to reduced overpotentials and favorable O→OOH energetics. The Nb/Ta sites facilitate charge transfer,
