A magnetically recoverable catalyst, WO/FeO, 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 and Fe/Fe species. Catalytic studies identified optimal conditions: 33 wt % WO loading, 40 mg catalyst, 10 equiv HO, 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/FeO as a promising, cost-effective, and easily recoverable catalyst for sustainable industrial oxidation processes.
通过共沉淀和煅烧方法成功合成了一种磁性可回收催化剂WO/FeO，并将其应用于苯乙烯选择性氧化制苯甲醛。结构和表面表征（XRD、XRF、SEM、TEM、BET、VSM和XPS）证实了两种组分的成功整合、介孔结构、强磁性以及W和Fe/Fe物种的存在。催化研究确定了最佳条件：WO负载量为33 wt%、催化剂40 mg、10当量的HO、70°C和24小时，苯乙烯转化率为74.21%，苯甲醛选择性为82.10%。该催化剂表现出优异的可回收性，在五个循环中保持了高活性和选择性。这些发现突出了WO/FeO作为一种有前景、经济高效且易于回收的催化剂，可用于可持续的工业氧化过程。
