ABSTRACT:
V2O5 nanoparticles were supported on mesoporous silica spheres
(V2O5/MSS) by impregnation technique. Where mesoporous silica sphere
(MSS) was synthesized via micelle-template method. The structure and
morphology were tested using XRD, FTIR, BET surface area, TEM, and DLS
techniques. The results demonstrated that the samples were amorphous with a
mesoporous structure, special interior spaces, and high specific surface area.
The prepared sample was tested for duel oxidative/adsorptive performance of
model diesel fuel. The desulfurization process was tested in the presence of
H2O2 as an oxidizing agent at different reaction conditions (temperature, contact
time, and initial concentration) using a batch system by either stirring or
ultrasonic. The data indicate that V2O5/MSS shows good performance toward
duel oxidative/adsorptive desulfurization with 100% removal efficiency under
sonication within 1.5h but in stirring within 2h at 60oC using 600 ppm initialconcentration.
