Optimizing Electrocatalytic Hydrogen Evolution Stability via Minimal Bubble Adhesion at Electrodeposited Crack-Structured NiPx Catalysts

引用

Energy & Environmental Materials 2024年第5期7卷 248-258页

作者： Qian Sun Xiaoyu Hao Dina Zhang Tianyi Zhang Yuanfang Zhao Xiaolei Huang xuqing liu State Key Laboratory of Solidification Processing Center of Advanced Lubrication and Seal Materials Northwestern Polytechnical University College of Art and Design Shenzhen University Institute of Material and Chemistry Ganjiang Innovation Academy Chinese Academy of Sciences Shandong Laboratory of Yantai Advanced Materials and Green Manufacture

In response to the ongoing energy crisis, advancing the field of electrocatalytic water splitting is of utmost significance, necessitating the urgent development of high-performance, cost-effective, and durable hydrogen evolution reaction catalysts. But the generated gas bubble adherence to the electrode surface and sluggish separation contribute to significant energy loss, primarily due to the insufficient exposure of active sites, thus substantially hindering electrochemical performance. Here, we successfully developed a superaerophobic catalytic electrode by loading phosphorus-doped nickel metal （NiPx） onto various conductive substrates via an electrodeposition method. The electrode exhibits a unique surface structure, characterized by prominent surface fissures, which not only exposes additional active sites but also endows the electrode with superaerophobic properties. The NiPx/Ti electrode demonstrates superior electrocatalytic activity for hydrogen evolution reaction, significantly outperforming a platinum plate, displaying an overpotential of mere 216 mV to achieve a current density of-500 mA cm-2in 1 M KOH. Furthermore,the NiPx/Ti electrode manifests outstanding durability and robustness during continuous electrolysis, maintaining stability at a current density of-10 mA cm-2over a duration of 2000 h. Owing to the straightforward and scalable preparation methods, this highly efficient and stable NiPx/Ti electrocatalyst offers a novel strategy for the development of industrial water electrolysis.

关键词： electrocatalyst gas bubble adhesion hydrogen evolution reaction long-term durability superaerophobic surface

破乳剂自动化投加控制是海上石油自动化生产核心,但是现行方法控制效果较差,在实际应用中不仅超投量比较高,而且石油生产合格率比较低,针对现行方法存在的不足和缺陷,提出海上石油生产过程中破乳剂自动化投加控制方法。结合FPSO现场仪表数据的特征,综合应用中位值滤波算法对石油生产数据滤波处理,利用学习模型估计油处理量及生产水量,利用专家经验模型确定破乳剂投加量,并对破乳剂投加时延控制,实现海上石油生产过程中破乳剂自动化投加控制。经实验证明,设计方法破乳剂超投量不足0.1%,海上石油生产合格率在99%左右,可以实现对破乳剂自动化投加精准控制。
