Abstract

The teams of Lu and Tian reported a halide ion modification strategy that endows a Pt cathode with strong anti-scaling capability while sustaining an efficient hydrogen evolution reaction during direct seawater electrolysis. The surface-bound halide ligand optimizes *H adsorption on adjacent Pt sites to boost Heyrovsky step and repels interfacial OH⁻ to shift the local pH maximum into the bulk electrolyte. These combined effects drive continuous hydrogen generation and high-purity Mg(OH)₂ precipitation without observable decay in a long-term stability measurement at 100 mA cm⁻² in direct seawater electrolysis.

在直接海水电解中持续制氢的电荷工程Pt和高纯度Mg(OH)2的联合生产

Lu和Tian的团队报告了一种卤化物离子修饰策略，该策略赋予Pt阴极强大的抗结垢能力，同时在海水直接电解过程中保持有效的析氢反应。表面结合的卤化物配体优化了*H在相邻Pt位点上的吸附，提高了Heyrovsky步进，并排斥界面OH -，将局部pH最大值转移到大块电解质中。这些综合效应驱动连续制氢和高纯度Mg(OH)2沉淀，在100 mA cm−2直接海水电解的长期稳定性测量中没有观察到衰减。

期刊介绍： Frontiers in Energy, an interdisciplinary and peer-reviewed international journal launched in January 2007, seeks to provide a rapid and unique platform for reporting the most advanced research on energy technology and strategic thinking in order to promote timely communication between researchers, scientists, engineers, and policy makers in the field of energy. Frontiers in Energy aims to be a leading peer-reviewed platform and an authoritative source of information for analyses, reviews and evaluations in energy engineering and research, with a strong focus on energy analysis, energy modelling and prediction, integrated energy systems, energy conversion and conservation, energy planning and energy on economic and policy issues. Frontiers in Energy publishes state-of-the-art review articles, original research papers and short communications by individual researchers or research groups. It is strictly peer-reviewed and accepts only original submissions in English. The scope of the journal is broad and covers all latest focus in current energy research. High-quality papers are solicited in, but are not limited to the following areas: -Fundamental energy science -Energy technology, including energy generation, conversion, storage, renewables, transport, urban design and building efficiency -Energy and the environment, including pollution control, energy efficiency and climate change -Energy economics, strategy and policy -Emerging energy issue
