A macroscopic 3D porous graphitic carbon nitride (g-CN) monolith is prepared by the one-step thermal polymerization of urea inside framework a commercial melamine sponge and exhibits improved photocatalytic water-splitting performance for hydrogen evolution compared to g-CN powder due interconnected network, larger specific surface area, better visible light capture, superior charge-separation efficiency.
Abstract Rechargeable sodium metal batteries (SMBs) have emerged as promising alternatives to commercial Li‐ion because of the natural abundance and low cost resources. However, overuse metallic in conventional SMBs limits their energy densities leads severe safety concerns. Herein, we propose a sodium‐free‐anode SMB (SFA‐SMB) configuration consisting sodium‐rich Na superionic conductor‐structured cathode bare Al/C current collector address above challenges. Sodiated 3 V 2 (PO 4 ) form 5 was...
The reversible and durable operation of sodium metal batteries at low temperatures (LT) is essential for cold-climate applications but plagued by dendritic Na plating unstable solid-electrolyte interphase (SEI). Current Coulombic efficiencies plating/stripping LT fall far below 99.9%, representing a significant performance gap yet to be filled. Here, the solvation structure conventional 1 m NaPF

Green energy storage devices play vital roles in reducing fossil fuel emissions and achieving carbon neutrality by 2050. Growing markets for portable electronics electric vehicles create tremendous demand advanced lithium-ion batteries (LIBs) with high power density, novel electrode material capacity density is one of the keys to next-generation LIBs. Silicon-based materials, specific capacity, abundant natural resources, high-level safety environmental friendliness, are quite promising...
Abstract Small molecule quinone compounds are attractive cathode materials for rechargeable aqueous zinc‐organic batteries (AZOBs) because of their structural diversity and low‐cost merits. Among them, nonpolar quinones dominant given the relatively low solubilities in electrolytes. However, poor electronic conductivity accumulated Coulombic repulsion lead to underutilized active sites sluggish redox kinetics. Here, polar 2,6‐dimethoxy‐1,4‐benzoquinone ( m ‐DMBQ) works as an advanced AZOB...
Alkali metal-air batteries (AMABs) promise ultrahigh gravimetric energy densities, while the inherent poor cycle stability hinders their practical application. To address this challenge, most previous efforts are devoted to advancing air cathodes with high electrocatalytic activity. Recent studies have underlined solid-liquid-gas triple-phase interface around anode can play far more significant roles than previously acknowledged by scientific community. Besides bottlenecks of uncontrollable...
The multielectron conversion electrochemistry of I–/I0/I+ enables high specific capacity and voltage in zinc–iodine batteries. Unfortunately, the I+ ions are thermodynamically unstable highly susceptible to hydrolysis. Current endeavors primarily focus on exploring interhalogen chemistry activate I0/I+ couple. However, practical working is below theoretical level. In this study, redox couple fully activated, efficiently stabilized by a chelation agent cost-effective urea conventional aqueous...
