Abstract Urea‐assisted water splitting is a promising energy‐saving hydrogen (H 2 ) production technology. However, its practical application hindered by the lack of high‐performance bifunctional catalysts for urea oxidation reaction (UOR) and evolution (HER). Herein, heterostructured catalyst comprising highly active NiSe Ni 3 Se , along with conductive graphene‐coated nickel foam skeleton (NiSe‐Ni /GNF) reported. The NiSe‐Ni originates from in situ selenization foam, allowing careful regulation to ratio simply adjusting calcination temperature. Theoretical calculations charge transfer between components can optimize pathways reduce corresponding energy barriers. Accordingly, designed exhibits excellent UOR HER activity stability. Furthermore, /GNF‐based UOR‐HER electrolyzer requires only 1.54 V achieve current density 50 mA cm −2 which lower than many recent reports much 1.83 OER‐HER electrolyzers. Moreover, exhibited negligible cell voltage variation during 28‐h stability test, indicating satisfactory stability, provides new viable paradigm H production.

Abstract Metal‐organic frameworks (MOFs) are highly versatile materials with tunable chemical and structural properties, making them promising for triboelectric nanogenerators (TENGs) electrocatalysis. However, achieving precise control over MOF coordination structures to optimize facet‐dependent properties remains challenging. Here, a facile scalable dual‐solvent synthesis strategy is presented fabricate dendrite Co‐2‐methylimidazole (ZIF‐67‐D), enabling tailored preferred facet environments. Using density functional theory (DFT) calculations synchrotron‐based X‐ray absorption spectroscopy, it demonstrated that ZIF‐67‐D, enriched (112) facets, features reduced Co number enhanced electron‐donating ability compared the conventionally (011) facet‐dominated rhombic dodecahedron ZIF‐67 (ZIF‐67‐R). This engineering boosts TENG charge by 2.4‐fold, OER current 9.9‐fold (@1.65 V), HER 1.9‐fold (@‐0.3 V). The (112)/(011) ratio can be also tuned precisely alter output. Moreover, optimized ZIF‐67‐D shows excellent stability, maintaining electrolyzer performance 72 h devices even in high humidity. Consequently, ZIF‐67‐D‐based (D‐TENG) exhibit robust energy generation power ZIF‐67‐D||ZIF‐67‐D electrolyzers continuous hydrogen (H 2 ) production. These findings introduce new paradigm converting mechanical into sustainable energy, offering insights high‐performance harvesting systems.

Abstract Triboelectric nanogenerators (TENGs) represent an effective approach for transforming mechanical energy into electrical power, making them suitable wearable electronic applications. Hydrogels as TENGs electrodes are common, but their use direct triboelectric layers remains insufficiently explored. Here, a novel zwitterionic monomer 3‐{1‐[6‐(hydroxymethyl)‐2‐methyl‐3,8‐dioxo‐9‐aza‐4,7‐dioxadodec‐1‐en‐12‐yl]imidazol‐3‐ium‐3‐yl}propane‐1‐sulfonate (VNIPS) is synthesized in combination with acrylic acid (AA) and sulfobetaine methacrylate (SBMA) to create double‐network hydrogel. The hydrogel developed using solvent‐exchange process that facilitated the creation of microphase‐separated domains, notablely increasing its strength (211.9 kPa, 472.3%), conductivity (0.6 mS cm −1 ), anti‐freezing capability (−18.3 °C). In addition, hydrogel's hydrophilic groups interacted water molecules, reducing charge loss humid conditions. When employed positive layer, hydrogel‐based achieved substantial density 456 µC m − 2 output power 464 mW , while maintaining steady open‐circuit voltage (V oc ) 97 V, 92% retention under 80% relative humidity. Moreover, strong adhesion biocompatibility make it applications, such motion sensing Morse code communication. This work demonstrates feasibility hydrogels materials, providing new strategy creating efficient, humidity‐resistant harvesters.
