Published: Aug. 5, 2024

Abstract The utilization of hydrazine in aiding water electrolysis presents a promising avenue for achieving highly efficient hydrogen production through energy conversion. Herein, bifunctional electrocatalyst urchin‐like iron, nickle‐codoped cobalt phosphide supported on Ni foam (FeNi‐CoP/NF) is reported. Benefitting from the combined electronic structure and lattice strain engineering by Fe Ni‐ codoping, hydrazine‐assisted seawater assembled with FeNi‐CoP/NF as both electrodes can achieve an industrial‐level current density 1.5 A cm −2 at record‐setting voltage 163 mV 70 °C sustain stable operation hundreds hours environment. existence potential coincidence region lends credibility to feasibility implementing self‐activated electrolysis. Based theoretical calculations, separate synergistic effects are investigated integrated illustration these two strategies enhancing evolution oxidation activity provided. Moreover, innovative multi‐powered generation system featuring direct fuel cell, rechargeable Zn‐hydrazine battery, proposed, underscoring unique advantages reaction its prospective contribution electrochemical conversion technologies powered sustainable sources.

Support Regulation Strategy Synergistic with Ru Single-Atom Catalyst for Energy-Saving Hydrogen Production Assisted by Green Electrosynthesis of Azotetrazolate

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 25, 2025

The slow kinetics of the oxygen evolution reaction limits electrochemical overall water splitting (OWS). To address this, integrating thermodynamically favorable organic electro-oxidation with hydrogen (HER) can enhance production performance. Notably, 5-amino-1H-tetrazole oxidation-assisted OWS not only achieves energy-saving but also produces energetic compound 5,5'-azotetrazolate salts in a mild manner. This necessitates in-depth research into catalysts straightforward synthesis methods and excellent performance for production. Supported single-atom (SACs) have high dispersibility reduce use precious metals. Here, we report highly efficient HER catalyst consisting Ru single atom anchored on low-crystallinity Zn-doped Ni2P nanosheets (Ru-LC-ZNP). low overpotential 28.9 mV at -10 mA cm-2, demonstrating stability least 100 h no noticeable activity loss. experimental results indicate that outstanding alkaline be attributed to synergistic optimization between support. By coupling 5-AT electro-oxidation, cell voltage electrolysis enormously reduced 1.26 V 10 cm-2. work provides insights mechanism supported SACs as active catalysts.
