The catalytic dehydration of glycerol into acrolein is a rapidly growing area of both scientific interest and technological importance. The main problem faced by researchers is enhancement of selectivity while maintaining the stability and activity of a catalyst. This minireview is centered on key approaches for tuning of selectivity: changing of physicochemical properties (type of acid sites, its amount, pore and channel size, and doping with noble metals) and selection of optimal reaction conditions (temperature, contact time, feedstock composition, co-feeding O₂ or air). This overview also proposes and discusses the use of metal-organic frameworks as novel catalysts to overcome the main challenges in the dehydration of glycerol.

甘油可持续生产丙烯醛的选择性调节

甘油催化脱水成丙烯醛是一个迅速发展的具有科学兴趣和技术重要性的领域。研究人员面临的主要问题是在保持催化剂稳定性和活性的同时提高选择性。这篇小综述集中在调节选择性的关键方法上：改变物理化学性质（酸位点的类型、数量、孔和通道尺寸以及贵金属掺杂）和最佳反应条件的选择（温度、接触时间、原料组成），共同喂食O ₂或空气）。该概述还提出并讨论了使用金属-有机骨架作为新型催化剂来克服甘油脱水的主要挑战。
