Down the Microporous Rabbit Hole of Silicoaluminophosphates: Recent Developments on Synthesis, Characterization, and Catalytic Applications

Since their invention silicoaluminophosphates (SAPOs) have become by far the most researched class of aluminophosphates due to their commercial use as solid acid catalysts. Currently over 25 different SAPO frameworks have been synthesized, providing a diverse range of confined nanoporous topologies, with distinct acid sites. When combined with emerging synthetic techniques to further modulate these species, there are endless possibilities to tailor SAPO materials for specific catalytic applications. Herein, this Review focuses on developments, and possibilities, from the past decade in the field of SAPO research, with particular attention paid to synthesis, characterization, theoretical studies, and case studies of their catalytic applications. I aim to simultaneously educate and inspire readers at all stages of their career and hope that this Review helps further interest and research into the exciting field of SAPOs.
