AI Technical Summary
In the existing allyl alcohol isomerization reaction, homogeneous catalysts have the problems of difficult separation and high cost, while the active metals of heterogeneous catalysts are prone to agglomeration and poor stability.
A solid core-shell catalyst with a transition metal as the core and an oxide as the shell is constructed through a preparation method to construct a porous structure and control the shell thickness to improve mass transfer efficiency, reduce the by-product adsorption capacity, and enhance catalyst stability.
High conversion rate and selectivity were achieved, with feedstock conversion rate ≥98.3% and product selectivity ≥88.1%. The activity of the catalyst remained basically unchanged within 100 hours, solving the problems of high catalyst separation cost and poor stability.
