N2 - The limited thermal and water stability of metal–organic frameworks (MOFs) often restricts their applications in conventional catalysis that involve thermal treatment and/or use of water. Non-thermal plasma (NTP) is a promising technique that can overcome barriers in conventional catalysis. Here we report an example of an NTP-activated water–gas shift reaction (WGSR) over a MOF (HKUST-1). Significantly, the exceptional stability of HKUST-1 was sustained under NTP activation and in the presence of water, which led to a high specific rate of 8.8 h −1 . We found that NTP-induced water dissociation has a twofold promotion effect in WGSR, as it facilitates WGSR by supplying OH and sustains the stability and hence activity of HKUST-1. In situ characterization of HKUST-1 revealed the critical role of open Cu sites in the binding of substrate molecules. This study paves the way to utilize MOFs for a wider range of catalysis.
