Evidence by ac-conductivity for the higher mobility of boron (over aluminium)-associated Brønsted sites in boron-modified HZSM-5
منشور في 1996"…Therefore, for this particular sample the electric data have been discussed in greater detail. Ruling out the perturbing role of dc-conduction, by analysis at both high frequencies and low temperatures where the dc-conduction is minimum, reveals conductivity increasing in the order: B1ZSM-5<B2ZSM-5<B3ZSM-5<B4ZSM-5 and activation energy decreasing in the order: B1ZSM-5>B2ZSM-5>B3ZSM-5>B4ZSM-5. …"
