Electrified methanol steam reforming (MSR) assisted by nonthermal plasma (NTP) is a pivotal enabler for clean hydrogen production at ambient conditions with several advantages. This study optimizes the NTP‐assisted MSR by catalyst engineering, as well as membrane technology (via a 2D MXene nanosheet membrane reactor). Our findings reveal that active‐phase engineering in catalyst design is crucial in regulating MSR pathways under NTP conditions with the bimetallic Ni–Cu alloys enhancing the H2 production via surface water–gas shift reaction (WGSR). Additionally, integrating a MXene membrane within a dielectric barrier discharge (DBD) NTP reactor enabled the reactive‐separation process, improving methanol conversion, H2 formation rate with higher purity, as well as showing a good stability.

通过在 MXene 膜反应器中进行催化剂工程,提高等离子体辅助甲醇蒸汽重整的 H2 产量



由非热等离子体 (NTP) 辅助的电气化甲醇蒸汽重整 (MSR) 是在环境条件下实现清洁制氢的关键推动因素,具有多项优势。本研究通过催化剂工程和膜技术(通过 2D MXene 纳米片膜反应器)优化了 NTP 辅助的 MSR。我们的研究结果表明,催化剂设计中的活性相工程对于在 NTP 条件下调节 MSR 途径至关重要,双金属 Ni-Cu 合金通过表面水-气体变换反应 (WGSR) 增强 H2 的产生。此外,在介电势垒放电 (DBD) NTP 反应器中集成 MXene 膜可实现反应分离过程,提高甲醇转化率、H2 生成速率和更高纯度,并显示出良好的稳定性。
