Abstract The development of durable, earth-abundant electrocatalysts for acidic water electrolysis is critical for large-scale green hydrogen production. Herein, we report a simple strategy to fabricate high-performance bifunctional electrodes by directly electrodepositing Ni(OH)2 nanostructures interfaced with P-derived species onto chemically activated, hydrophilic carbon rod substrates. Surface oxidation of the carbon rod effectively removes surface impurities, enhances...

Abstract Developing cost-effective, durable, and efficient bifunctional electrocatalysts is essential for advancing green hydrogen production. Here, we report a rapid, one-step, room-temperature, corrosion-driven strategy for directly constructing nickel-iron layered double hydroxides (NiFe LDH) on nickel foam (NF), where the NF serves as both the conductive substrate and the sole Ni source. In an Fe3 + -ethylene glycol...

Abstract Temporal knowledge graphs (TKGs) represent real-world facts evolving over time by incorporating the multirelational structure of knowledge graphs with temporal dimensions. While extensions of graph convolutional networks, such as relational and composition-based variants, have demonstrated strong capabilities in modeling graph-structured data, effectively capturing both symmetric and asymmetric relational dependencies, their application to TKG reasoning...
