文摘
- •
Spherical millimeter-sized mesoporous γ-Al2O3 beads are selected as catalyst carrier.
- •
Surface of the beads is functionalized with amino groups.
- •
Phosphotungstic acid is stably anchored on the beads via electrostatic interaction.
- •
The obtained materials show excellent oxidative desulfurization for DBT.
- •
Remarkable advantages are witnessed for the obtained materials.
