摘要

我们报告了一个意想不到的催化性能乙醇脱水脱铝β沸石与框架铝物种的水平低至120 ppm。通过IPA-TPD反应、正丁醇探针反应和DFT计算证实，残铝组分起主导作用。

Is trace-level aluminum in zeolite matrix catalytically inert? A case study of alcohol dehydration in dealuminated beta zeolite†

We report an unanticipated catalytic performance for ethanol dehydration in dealuminated Beta zeolite with framework aluminum species at levels as low as 120 ppm. The residual aluminum species playeda dominant role, as proved by IPA-TPD, an n-butanol probe reaction, and DFT calculations.
