The generation of silicon dioxideยฑaluminum oxide compound clusters under 308 nm XeCl excimer laser ablation of ZSM-5 zeolites with dierent SiO 2 /Al 2 O 3 ratios was studied by time-of-ยฏight mass spectrometry. Two Al-containing cluster sequences [(SiO 2 ) nร1 (AlO 2 )] ร and [(SiO 2 ) n OAl] ร are o
