Mechanochemical Pretreatment for Efficient Solvent‐Free Synthesis of SSZ‐13 Zeolite

Abstract The economical and environmentally benign synthesis of SSZ‐13 zeolite was possible due to the mechanochemical activation of dry reagents by planetary mill. Contrary to manual grinding in a mortar, the proposed automatized approach is scalable and reproducible. This solvent‐free process provided a huge gain in product/gel ratios, significantly minimized reaction space and organic structure‐directing agent use, and allowed for the elimination of agitation. Obtained materials were comparable to the product of “classical” syntheses. The use of different silica sources resulted in SSZ‐13 zeolites with various characteristics: different Si/Al ratio and crystal size.
