Enhancing H2 production from plasma‐assisted methanol steam reforming by catalyst engineering in a MXene membrane reactor

Abstract 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 H 2 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, H 2 formation rate with higher purity, as well as showing a good stability.
