Abstract: High Resolution Image Download MS PowerPoint Slide A magnetically recoverable catalyst, WO 3 /Fe 3 O 4, was successfully synthesized via a coprecipitation and calcination method and applied for the selective oxidation of styrene to benzaldehyde. Structural and surface characterizations (XRD, XRF, SEM, TEM, BET, VSM, and XPS) confirmed the successful integration of both components, mesoporosity, strong magnetic properties, and the presence of W 6+ and Fe 2+ /Fe 3+ species. Catalytic studies identified optimal conditions: 33 wt % WO 3 loading, 40 mg catalyst, 10 equiv H 2 O 2, 70 °C, and 24 h, resulting in a styrene conversion of 74.21% and a benzaldehyde selectivity of 82.10%. The catalyst exhibited excellent recyclability, maintaining high activity and selectivity across five cycles. These findings highlight WO 3 /Fe 3 O 4 as a promising, cost-effective, and easily recoverable catalyst for sustainable industrial oxidation processes.
