Abstract A novel N-doped SiO2@SiC core shell has been synthesized and functionalized with amino groups. Then, amino hybrid of tungsten oxide was supported on the surface of functionalized SiO2@SiC core shell by immobilization of tungsten complex and coordination of ethylenediamine to tungsten centers. Then, the catalytic activities of prepared hybrids were investigated in oxidative desulfurization of model fuels. To evaluate the role of silicon carbide support, silica nanospheres also were functionalized and its catalytic performance was compared. The results indicate that the SiC catalyst shows higher catalytic activity (99.9%, 160 min) compared to the SiO2 analogue (61%, 160 min).

新型多孔 SiO2@SiC 核壳纳米球用 WO3 的氨基杂化物功能化作为氧化脱硫催化剂

摘要 合成了一种新型的 N 掺杂 SiO2@SiC 核壳并用氨基官能化。然后，通过钨配合物的固定和乙二胺与钨中心的配位，将氧化钨的氨基杂化物负载在功能化的 SiO2@SiC 核壳表面。然后，研究了制备的杂化物在模型燃料氧化脱硫中的催化活性。为了评估碳化硅载体的作用，还对二氧化硅纳米球进行了功能化，并比较了其催化性能。结果表明，与 SiO2 类似物（61%，160 分钟）相比，SiC 催化剂显示出更高的催化活性（99.9%，160 分钟）。
