Silicoaluminophosphate zeolite (SAPO‐34) has been attracting increasing attention due to its excellent form selection and controllability in the chemical industry, as well as being one of the best industrial catalysts for methanol‐to‐olefin (MTO) reaction conversion. However, as a microporous molecular sieve, SAPO‐34 easily generates carbon deposition and rapidly becomes inactivated. Therefore, it is necessary to reduce the crystal size of the zeolite or to introduce secondary macropores into the zeolite crystal to form a hierarchical structure in order to improve the catalytic effect. In this review, the synthesis methods of conventional SAPO‐34 molecular sieves, hierarchical SAPO‐34 molecular sieves and nanosized SAPO‐34 molecular sieves are introduced, and the properties of the synthesized SAPO‐34 molecular sieves are described, including the phase, morphology, pore structure, acid source, and catalytic performance, in particular with respect to the synthesis of hierarchical SAPO‐34 molecular sieves. We hope that the review can provide guidance to the preparation of the SAPO‐34 catalysts, and stimulate the future development of high‐performance hierarchical SAPO‐34 catalysts to meet the growing demands of the material and chemical industries.

“…As the third most abundant element in the Earth’s crust, aluminum (Al) has been widely applied in the building, automotive, electrical distribution industries, etc. and especially commonly used in the metallic items [1] , [2] . Correspondingly, its oxides alumina (Al 2 O 3 ) possess wide industrial applications, and the most massive-scale use for alumina production [3] , [4] .…”

“…Hence, the use of ultrasound along with high temperature hydrothermal synthesis as alternative routes is proposed for preparation of MFI aluminosilicate framework. Sonochemistry involves high energies and pressure on a short time scale [34] . This can be due to acoustic cavitation which created small bubbles by ultrasonic waves and collapse of micro-bubbles that produced tremendous heat and pressure [27] , [31] , [35] .…”
