Electrolysis of seawater is currently a promising technology for efficient green hydrogen production and solving the energy crisis. Urea oxidation reaction (UOR) has low thermodynamic onset potential, which an effective to replace oxygen evolution (OER) in overall splitting avoid toxic hypochlorite generation. In this paper, we report sulfur-doped NiFe LDH with ultrathin nanoflower morphology on surface three-dimensional nickel foam (NF) loaded Ti3C2Tx MXene by two-step electrodeposition method (S-NiFe LDH/MXene@NF). The catalytic performance electrolytic boosted synergistic effect abundant interface between LDH, promotes electron transfer. S-NiFe LDH/MXene@NF exhibited electrocatalytic values 1.578 1.437 V (vs RHE) OER UOR at 500 mA cm–2, respectively, overpotential 336 mV (HER) cm–2 alkaline electrolyte. As bifunctional electrode, it can achieve current density 2.027 great stability. situ Raman detection recombination electrode demonstrates that accelerates formation active species NiOOH facilitates lattice disturbance NiOOH. This helps increase activity urea-assisted splitting.

Hydrogen is a prime candidate for replacing fossil fuels. Electrolyzing water to produce hydrogen stands out as particularly clean method, garnering significant attention from researchers in recent years. Among the various techniques electrolyzing hydrogen, alkaline electrolysis holds most promise large-scale industrialization. The key advancing this technology lies development of durable and cost-effective electrocatalysts evolution reaction (HER). Self-supporting electrode an structure which catalyst layer formed directly on substrate (such carbon cloth, nickel foam, stainless steel, etc) without using binder with good structural stability. In contrast traditional nanocatalysts, self-supporting offer advantages, including reduced resistance, enhanced stability, prolonged usability under high currents. This paper reviews advancements HER electrochemical catalysts electrolysis, focusing utilization hydrogen-evolving such metal sulfides, phosphides, selenides, oxides, hydroxides. With self-supported focal point, delves into progress made their preparation techniques, design, understanding mechanisms, strategies performance enhancement. Ultimately, future direction promoting by summarized.
