Oxidative Desulfurization Catalyzed by Phosphotungstic Acid Supported on Hierarchical Porous Carbons

Abstract

A hierarchical porous carbon material (HPC) with an ultra-high specific surface area was synthesized with sisal fiber (SF) as a precursor, and then H3PW12O40•24H2O (HPW) was immobilized on the support of SF−HPC by a simple impregnation method. A series characterization technology approved that the obtained SF−HPC had a high surface area of 3152.46 m2g−1 with micropores and macropores. HPW was well-dispersed on the surface of the SF−HPC support, which reduced the loading of HPW to as low as 5%. HPW/SF-HPW showed excellent catalytic performance for oxidative desulfurization, and the desulfurization rate reached almost 100% under the optimal reaction conditions. The desulfurization rate of HPW/SF-HPW could be maintained at above 94% after four recycles.

“…Biomass carbon is a renewable resource. Porous carbon materials possess a high specific surface area, controllable aperture, good thermal conductivity, good adsorption performance and stable chemical properties, 22 and porous carbon materials have great potential in catalysis, 23 adsorption and electrochemical sensor. 24 Zhang et al 25 found a nano-ZnS decorated hierarchically porous carbon (ZSHPC) that was prepared using waste biomass as a carbon source, ZnCl 2 as a zinc source and activator, sulfuric acid as a sulfur source, and silica gel as a hard template.…”
