A fast crystallization of TUN zeolite via the interzeolite conversion method

Abstract A TUN-type aluminosilicate zeolite was rapidly synthesized via the interzeolite conversion method (IZC) using a MWW-type one as a starting material. It was found that the co-addition of the organic structure direct agent (OSDA) and the seed played a crucial role in accelerating the crystallization of the TUN phase. The TUN zeolite synthesized via the IZC method exhibited comparable physicochemical properties to those of the conventional one crystallized from amorphous silica and alumina materials.
