Carbenium ions in zeolites : Two important carbenium ions have been observed for the first time under working conditions of the methanol‐to‐olefins (MTO) reaction over chabazite zeolites using 13 C NMR spectroscopy. Their crucial roles in the MTO reaction cycles have been demonstrated by combining experiments and theoretical calculations.
