1) 北京大学：齐利民课题组2023.06.02在 Advanced Functional Materials 发表的Electronic and Vacancy Engineering of Mo-RuCoOx Nanoarrays for High-Efficiency Water Splitting，并在支持文献中提到”The water used throughout all experiments was deionized and purified through a Millipore system.”

2) 兰州大学：席聘贤课题组2023.04.07在Nature Communications 发表的Understanding the sulphur-oxygen exchange process of metal sulphides prior to oxygen evolution reaction 中也提到”The deionized(DI) water for solution preparation was from a Millipore system”

3) 厦门大学与电子科技大学：梁汉锋团队联合江秋团队2023.08.07在Journal of the American Chemical Society 发表的Direct Dioxygen Radical Coupling Driven by Octahedral Ruthenium-Oxygen-Cobalt Collaborative Coordination for Acidic Oxygen Evolution Reaction的支持信息中提到“the distilled water(10-15 MΩ.cm)used throughout all experiments was purified through a Millipore system.”

4) 复旦大学：吴仁兵团队2023.05.24在ACS Catalysis发表的Inert Mg incorporation to Break the Activity/Stability relationship in High-Entropy layered hydroxides for the Electrocatalytic Oxygen Evolution Reaction中提到“The deionized water(18 MΩ.cm) used in all experiments was purified through a Millipore system.”

为什么水质对于制氢的很重要呢？

“电解”是生产纯氢的主要过程。这种“电转气”方法需要纯化水才能使电解槽本身达到最佳性能，并最终获得高品质产品。尤其是水中常见的污染物可能会对电解造成不同程度的影响：

低电导率对于电解槽的良好运行至关重要，因为离子杂质可能会降低膜的性能，甚至缩短其寿命

低TOC含量可以防止在电极表面形成有机沉积物，这对于局部电流可能造成潜在影响

稳定的水质支持持续供应大量容的高纯度氢气
