Zeolites are microporous silicates with a large variety of applications as catalysts, adsorbents, and cation exchangers. Stable silica-based zeolites increased porosity in demand to allow adsorption processing molecules but challenge our synthetic ability. We report new, highly stable pure silica zeolite called ZEO-3, which has multidimensional, interconnected system extra-large pores open through windows made by 16 14 silicate tetrahedra, the least dense polymorph known so far. This was formed an unprecedented one-dimensional three-dimensional (1D-to-3D) topotactic condensation chain silicate. With specific surface area more than 1000 square meters per gram, ZEO-3 showed high performance for volatile organic compound abatement recovery compared other metal-organic frameworks.
