摘要

Graphical abstract

Reaction mechanism for the synthesis of PODEnon Br?nsted and Lewis acid sites.

Display Omitted

Highlights

?SO42?/TiO2catalysts highly active for PODEnsynthesis were prepared.

?Activity showed a volcano relationship with precursor solution concentration.

?Spatial distribution of S strongly affected acid properties and catalyst activity.

?Synergetic effect existed between Br?nsted and Lewis sites for PODEnsynthesis.

?New catalytic mechanism was proposed based on Br?nsted and Lewis acid sites.
