Tuning of Selectivity for Sustainable Production of Acrolein from Glycerol

Abstract 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 O 2 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.
