Guaiacol, a key product of catalytic fast pyrolysis of lignocellulosic biomass, exhibits complex behaviour in ZSM-5, yet direct experimental evidence of zeolite-guaiacol host-guest interactions has been lacking. Here, we directly identify distinct in-pore and ex-pore guaiacol species in adsorbed ZSM-5 and trapped unreacted species following catalytic upgrading. These species are distinguished using 1H and 13C magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy differentiating through characteristic differences in chemical shifts, linewidths and relaxation data observables, and are complemented by thermogravimetric analysis coupled with mass spectrometry (TGA-MS) to reveal differences in their desorption profiles. Furthermore, 17O isotopic enrichment of the ZSM-5 framework enables two-dimensional 1H-17O dipolar heteronuclear multiple-quantum coherence (D-HMQC) NMR experiments, providing molecular-level insight into the through-space interactions between guaiacol and framework oxygen atoms. Together, these results suggest the location, confinement and reactivity of guaiacol within ZSM-5 pores, offering atomic-scale observations for the rational design of future zeolite catalysts for sustainable fuel production. 2026-05-26 published University of Liverpool 10.17638/datacat.liverpool.ac.uk/3086 Johnson Matthey (United Kingdom) (JM) EP/X524955/1 Engineering and Physical Sciences Research Council (EPSRC) EP/T015063/1 Biotechnology and Biological Sciences Research Council (BBSRC) EP/S013393/1 University of Liverpool R21-2293948533 Royal Society of Chemistry (RSC) English 1042097
