采用简单的一锅溶剂热法制备了mnfe2o4空心纳米球。采用XRD、SEM、TEM、FTIR和紫外-可见吸收光谱对产物进行了表征。在可见光照射下，苯可以在mnfe2o4纳米球上有效降解。利用原位FTIR技术，可以将乙酸乙酯、羧酸、醛和乙炔作为中间产物，在反应过程中产生co2作为最终矿化产物。通过光致发光技术证实了羟基自由基是光催化反应中的活性物质。
MnFe2O4hollow nanospheres were successfully fabricated via a facile one-pot solvothermal method. The prepared products were characterized by XRD, SEM, TEM, FTIR and UV–Vis absorption spectroscopy analyses. Benzene can be effectively degradated on the MnFe2O4nanospheres when irradiated with visible light. By using the in situ FTIR technique, ethyl acetate, carboxylic acid, aldehyde and acetylene could be regarded as the intermediate products, and CO2was produced as the final mineralization product during the reaction process. Hydroxyl radicals were confirmed as active species in the photocatalytic reaction by the photoluminescence technique.
