Abstract
The fabrication of polyoxometalates (POMs)-modified TiO2 catalysts with connected pore structure has attracted great interests due to its prominent effect on mass transfer and catalytic oxidation activity. Here, we report a series of hierarchically macro/mesoporous (M/m) phosphotungstic acid (HPW)/TiO2 composites, which are fabricated by colloidal crystal template method and applied as deep desulfurization catalyst in fuel oil. As-synthesized hierarchical HPW/TiO2 composite is interconnected by ordered macroporous channel with disordered mesoporous embedded on pore walls. Moreover, Keggin-type HPW is homogeneously dispersed on the TiO2 matrix. Hierarchical macro/mesoporous HPW/TiO2 shows an excellent catalytic performance, the removal rate for dibenzothiophene in model fuel reaches 99% under the optimum conditions. This high performance of the three-dimensional ordered macropores (3DOM) HPW/TiO2 can be attributed to its hierarchically porous which is highly beneficial for the mass transfer during the catalytic process. Moreover, the used catalyst could be regenerated by centrifugation and only slight decreasing of the catalytic activity after five cycles.
