Abstract

[3-Piperazinepropylmethyldimethoxysilane (PZPMS)] as a low-cost co-template, a crystal growth inhibitor, and a part of the silica source was used together with triethylamine to synthesize SAPO-34 nanoaggregates with tunable compositions. Note that the piperazinyl group of PZPMS prompts the formation of a perfect CHA structure by eliminating the CHA/AEI intergrowth, which ensures the excellent MTO catalytic performance of SAPO-34 nanoaggregates.
