A facile spray pyrolysis method is introduced to construct the hollow CeO-AlO spheres with atomically dispersed Fe. Only nitrates and ethanol were involved during the one-step preparation process using the ultrasound spray pyrolysis approach. Detailed explorations demonstrated that differences in the pyrolysis temperature of the precursors and heat transfer are crucial to the formation of the hollow nanostructure. In addition, iron species were in situ atomically dispersed on the as-formed CeO-AlO hollow spheres via this strategy, which demonstrated promising potential in transferring syn-gas to valuable gasoline products.
引入一种简便的喷雾热解法来构建具有原子分散铁的空心CeO-AlO球。在使用超声喷雾热解方法的一步制备过程中，仅涉及硝酸盐和乙醇。详细研究表明，前驱体热解温度和热传递的差异对空心纳米结构的形成至关重要。此外，通过该策略，铁物种原位原子分散在形成的CeO-AlO空心球上，这在将合成气转化为有价值的汽油产品方面显示出有前景的潜力。
