摘要

直接海水电解是利用地球上最丰富的水资源生产绿色氢的一种有希望的方法，但其阳极容易受到氯化物引起的腐蚀。本研究证明，在Ni泡沫上负载ba掺杂NiFe层状双氢氧化物（Ba-NiFe LDH/NF）是一种高性能的碱性海水氧化阳极。这种Ba-NiFe LDH/NF只需要342 mV的过电位就可以达到1000 mA cm-2，并且稳定运行1500 h，降解可以忽略，活性氯的产生最少。Ba的掺杂不仅加速了催化剂的表面重构，而且有利于OH-和Cl-在阳极上的选择性吸附。由Ba-NiFe LDH/NF和Pt/C/NF组成的膜电极组合电解槽在1000 mA cm-2下稳定运行500 h。

Durable Ampere-Scale Seawater Electrolysis Driven by Ba-Doped NiFe Layered Double Hydroxide.

Direct seawater electrolysis is promising for green hydrogen production from earth's most abundant water resource, but its anode suffers from chloride-induced corrosion. Herein, Ba-doped NiFe layered double hydroxide supported on Ni foam (Ba-NiFe LDH/NF) is demonstrated as a high-performance anode for durable alkaline seawater oxidation. Such Ba-NiFe LDH/NF needs only an overpotential of 342 mV to achieve 1000 mA cm-2 and operates stably for 1500 h with negligible degradation and minimal active chlorine generation. Ba doping not only accelerates catalyst surface reconstruction but also favors the selective adsorption of OH- vs Cl- over the anode. The membrane electrode assembly electrolyzer composed of Ba-NiFe LDH/NF and Pt/C/NF demonstrates stable operation at 1000 mA cm-2 for 500 h.
