CO2 captured by silicoaluminophosphate (SAPO) zeotypes

Abstract

Excess carbon dioxide (CO2) in the atmosphere is causing great harm to the environment. Silicoaluminophosphate (SAPO) zeotypes have attracted great attention in CO2 capture. In this review, we comprehensively summarized and discussed the advances in the CO2 adsorption by SAPO zeotypes, the factors affecting the CO2 capture such as topologies, cation types, and amine modifications, and the interaction between the H2O, SOx, and NOx and the framework of SAPOs as well as their influence on the CO2 adsorption performance. At the end of the review, we raised the key challenges, current trends in the development of SAPO zeotypes, future research directions, and possible solutions to achieve the deployment of effective SAPO materials in CO2 capture.
