The dynamics of tetrapropylammonium (TPA) cations occluded during the synthesis of a siliceous MFI zeolite were investigated by several 13C high-resolution NMR methods. This work follows and complements a previous 1H broad-line NMR study of this material. The evolution of the 13C cross polarization

✦ Synopsis
Shaping zeolites into useful forms is very important for technical applications in areas such as catalysis, separation, and sensing. Normally it is difficult to form zeolites into appropriate shapes without mixing them with binders. Here, a method is presented for transforming preformed layered silicates into silicalite zeolites (e.g. see Figure). magnified image
