Figure 4
FT-IR spectra of chlorobenzene and NO2 in NaZSM-5 at 50°C: (a) at time ; (b) difference between zeolite + chlorobenzene (Figure 2) and zeolite + chlorobenzene + NO2 (trace a) highlighting the NO2 bands under the initial reaction conditions; (c) after 240 min of reaction; (d) difference between time (trace a) and min (trace c).
