Novel porous SiO2@SiC core-shell nanospheres functionalized with an amino hybrid of WO3 as an oxidative desulfurization catalyst
E-mail:
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).
