Vanadia nanoparticles encapsulated in mesoporous silica as a rattle-like structure for oxidation of dibenzothiophene: A kinetic study

A rattle-like structure of V2O5 encapsulated in mesoporous silica was successfully prepared through a surfactant-supported selective etching strategy. The structural analysis showed that V2O5 nanoparticles in the core of mesoporous hollow silica spheres with void diameter ∼290 nm, V2O5 core diameter...
