A fast crystallization of TUN zeolite via interzeolite conversion method

Abstract The TUN-type aluminosilicate zeolite was rapidly synthesized via the interzeolite conversion method (IZC) using 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. Thus-synthesized TUN zeolite via the IZC method exhibited comparable physicochemical properties to those of conventional one crystallized from amorphous silica and alumina materials.
