Abstract

In a recent issue of Nature Catalysis, Zhou et al. introduce an innovative cobaltosilicate zeolite with solely tetrahedral cobalt sites (CoS-1) for propane dehydrogenation. By eliminating unstable cobalt species through acid wash, CoS-1 mitigates coke formation and framework degradation. The catalyst outperforms benchmark Pt–Sn catalysts over multiple dehydrogenation-regeneration cycles.

具有分离的四面体钴位的钴硅酸盐沸石用于丙烷的高效脱氢

在最近一期的《自然催化》杂志上，Zhou等人介绍了一种创新的钴硅酸盐沸石，它只有四面体钴位（CoS-1），用于丙烷脱氢。通过酸洗去除不稳定的钴种，CoS-1减轻了焦炭的形成和骨架的降解。该催化剂在多次脱氢再生循环中优于基准Pt-Sn催化剂。
