ZSM-5 with controllable acidity as an efficient catalyst for a highly adjustable propene/ethene ratio in the 1-butene cracking

A facile strategy was proposed to realize the precise control of zeolitic acidity by selective cracking of a silane with an acid site. Modified ZSM-5 with controllable acidity brought about a highly adjustable propene/ethene (P/E) ratio in the 1-butene cracking.
