A hierarchical porous carbon material (HPC) with an ultra-high specific surface area was synthesized with sisal fiber (SF) as a precursor, and then HPWO·24HO (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 mg 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.
以剑麻纤维（SF）为前驱体合成了具有超高比表面积的分级多孔碳材料（HPC），然后通过简单的浸渍法将HPWO·24H₂O（HPW）负载在SF-HPC载体上。一系列表征技术证实，所制备的SF-HPC具有3152.46 mg的高比表面积，且同时含有微孔和大孔。HPW很好地分散在SF-HPC载体表面，使得HPW的负载量降低至5%。HPW/SF-HPW在氧化脱硫反应中表现出优异的催化性能，在最佳反应条件下脱硫率几乎达到100%。经过四次循环后，HPW/SF-HPW的脱硫率仍可保持在94%以上。
