The MCM-22 zeolite was produced using diatom as the green silica source through the vapor phase transport assisted-synthesis. This study shows that this process is essential as, in classical rotation conditions, only an amorphous material is produced. The diatomite-MCM-22 zeolite catalytic activity was tested in the degradation of low and high-density polyethylene as a probe reaction. The results obtained were similar to those obtained with an MCM-22 synthesized with commercial fumed silica.

气相传输合成法将硅藻分解为MCM-22沸石

使用硅藻作为绿色二氧化硅源通过气相传输辅助合成法生产MCM-22沸石。这项研究表明，此过程至关重要，因为在经典旋转条件下，只会产生一种非晶态材料。测试了硅藻土-MCM-22沸石在低密度和高密度聚乙烯降解中的催化活性，作为探针反应。获得的结果类似于使用由商业气相二氧化硅合成的MCM-22获得的结果。
