Highly durable and efficient hydrogen production from alkaline seawater using pulse-deposited NiMoP nanosphere electrocatalysts
使用脈衝電鍍 NiMoP 奈米球觸媒從鹼性海水中高效且耐久產氫
📄 英文摘要
This study describes the synthesis of high-performance cauliflower-like NiMoP nanosphere electrocatalysts on a titanium mesh via a scalable pulse electrodeposition technique. The optimized cauliflower-like NiMoP demonstrates remarkable activity for the hydrogen evolution reaction in alkaline seawater, requiring only 50.3 mV overpotential to drive 10 mA cm⁻² and exhibiting exceptional durability, with only 0.5% current degradation over 24 hours. This superior performance is attributed to a unique combination of an amorphous structure, a high-surface-area morphology, and synergistic electronic effects among the Ni, Mo, and P components.

本研究利用可規模化的脈衝電鍍技術，在鈦網上合成高性能花椰菜狀 NiMoP 奈米球觸媒。最佳化的花椰菜狀 NiMoP 在鹼性海水中展現卓越的氫析出反應（HER）活性，僅需 50.3 mV 的過電位即可達到 10 mA cm⁻²，且具有出色的耐久性——連續運行 24 小時後電流衰減僅 0.5%。此優異性能歸因於其非晶結構、高比表面積形貌，以及 Ni、Mo、P 三元素間的協同電子效應之獨特組合。
