AI Article Synopsis
- HPM-16 is a specialized zeolite made of germanosilicate, featuring a highly porous structure with both 12-membered and 10-membered ring pores, allowing for a complex three-dimensional connectivity.
- The unique arrangement includes long tubular supercages formed by 10-membered ring pores that merge into fused pores, which are coated with T-OH groups, creating regions that attract water molecules.
- Despite its complex framework, HPM-16 shows great potential for stability and durability after significant processing to remove germanium, making it useful in various applications.
Article Abstract
HPM-16 is a highly porous germanosilicate zeolite with an interrupted framework that contains a three-dimensional system of 12+10×10(12)×12+10-membered ring (MR) pores. The 10(12) MR pore in the b direction is a 10 MR pore with long 12 MR stretches forming 30 Å long tubular supercages. Along one direction the 10 MR pores are fused, meaning that the separation between adjacent pores consists of a single tetrahedron that is, additionally, connected to only three additional tetrahedra (a Q ). These fused pores are thus decorated by T-OH groups along the whole diffusion path, creating a hydrophilic region embedded in an otherwise essentially hydrophobic environment. The structure is built from highly porous 12×12×12 MR uninterrupted layers that are connected to each other through Q producing a second system of 10×10×10 MR pores. This zeolite can be extensively degermanated yielding a material with high thermal stability, despite its interrupted nature.
