The acid sites in dealuminated HZSM-5 zeolite with crystal sizes down to the nanoscale were firstly characterized by the probe molecule trimethylphosphine (TMP). As evidenced by the combination of 31 P CP/MAS NMR, 27 Al MAS and 1 H β†’ 27 Al CP/MAS NMR measurements, the BrΓΆnsted acid sites of both mic
