Representative metal oxide and non-metal element modified SBA-15: synthesis methods and performance.
| Metal Oxide/ Non-Metal Element |
Synthesis Methods | Reaction/Application | Performance | Ref. |
|---|---|---|---|---|
| Al2O3 | One-step wet impregnation | 1-butene metathesis to propene | Enhanced conversion and selectivity; stable catalytic activity | [60] |
| ZnO | Ultrasonic impregnation | Photocatalytic degradation of methylene blue dye | High catalytic activity and stability | [61] |
| Fe3O4 | Carrier-based synthesis | Activation of persulfate for pollutant removal | Efficient activation; high removal rate of pollutants | [62] |
| Co3O4 | Not specified | Fischer–Tropsch synthesis | Decreased specific surface area of SBA-15; co-present as Co3O4 | [63] |
| CeO2 | Doping | Biodiesel production from Podocarpus falcatus oil | High biodiesel yield under optimized conditions | [64] |
| Fe2O3 | Wet impregnation | Degradation of methylene blue | 70.2% efficiency under visible light irradiation | [65] |
| Phosphorous acid | Post-grafting | Adsorption of Gd(III) | Excellent adsorption capacity and kinetics; good reusability | [66] |
