摘要: Abstract Hydrothermal synthesis of chabazite-like AlPO 4 in a fluoride medium, using piperidine as the structure directing agent, is also successful preparation transition-metal-modified products. The transition metal (Co, Mn, and Ni) has no influence on triclinic deformation chabazite framework, formed by an interaction ions with framework. Upon calcination, successive destruction bridges occurs. calcined products exhibit particular sensitivity for humidity resulting new framework completely reversible can be removed dehydration. transition-metal incorporation exerts dehydration process.
