Title
Recyclable HPW/PEHA/ZrSBA-15 toward efficient oxidative desulfurization of DBT with hydrogen peroxide
Abstract

•Efficient oxidative desulfurization of DBT over heterogeneous catalyst with H2O2•Factors for the removal rate of DBT were thoroughly investigated.•Excellent catalytic performance and recyclability under solvent-free conditions

A layer-by-layer stabilization strategy was employed to immobilize active tungstophosphoric acid onto pentaethylenehexamine-preloaded acidic ZrSBA-15 with short pore channels. The composites were used as catalysts for the deep desulfurization of dibenzothiophene with hydrogen peroxide as green oxidant. The catalyst exhibited excellent desulfurization activity under optimum testing conditions. Moreover, it could be recovered and reused for six reaction runs without a discernible decrease in its activity.
