英文摘要	Strong metal-support interaction (smsi) has been regarded as one of the most important concepts in heterogeneous catalysis, which has been almost exclusively discussed in metal/oxide catalysts. here, we show that gold/molybdenum carbide (au/mocx) catalysts feature highly dispersed au overlayers, strong interfacial charge transfer between metal and support, and excellent activity in the low-temperature water-gas shift reaction (lt-wgsr), demonstrating the active smsi state. subsequent oxidation treatment results in strong aggregation of au nanoparticles, weak interfacial electronic interaction, and poor lt-wgsr activity. the two interface states can be transformed into each other by alternative carbonization and oxidation treatments. this work reveals the active smsi effect in metal/carbide catalysts induced by carbonization, which opens a new territory for this important concept.
