二维沸石及其在大分子催化转化领域的研究进展

与三维结构沸石不同,二维沸石由于其更开放的孔道结构、更大的比表面积、更易暴露的酸性位点,在大分子和扩散限制催化领域显示了特殊优势。通过各种合成和后处理方法,能够调控二维沸石及其衍生材料的孔道种类、大小与分布,从而适用于不同的催化过程。本文综述了近年来二维沸石的合成与应用进展。

Progress of Two-Dimensional Zeolites and Their Applications in Bulky Molecule Catalytic Conversion

Compared with three-dimensional zeolites, two-dimensional zeolites possess the more open skeleton structure, larger specific surface area and more exposed acid sites, resulting in special advantages in bulky molecule catalysis or diffusion-limited catalysis. Through diverse direct synthesis methods or postprocessing methods, pore species, pore size and pore distribution of two-dimensional zeolites and derived materials can be adjusted to be suited for various catalysis processes. Here, we summarize the recent progress of two-dimensional zeolites including syntheses and applications.
