| Abstract: | We have developed nanoparticle‐embedded paper‐spray mass spectrometry for studying three types of heterogeneously catalyzed reactions: 1) Palladium‐nanoparticle‐catalyzed Suzuki cross‐coupling reactions, 2) palladium‐ or silver‐nanoparticle‐catalyzed 4‐nitrophenol reduction, and 3) gold‐nanoparticle‐catalyzed glucose oxidation. These reactions were almost instantaneous on the nanocatalyst‐embedded paper, which subsequently transferred the transient intermediates and products to a mass spectrometer for their detection. This in situ method of capturing transient intermediates and products from heterogeneous catalysis is highly promising for investigating the mechanism of catalysis and rapidly screening catalytic activity under ambient conditions. |
