Urea used in fertilization and feed supplement, as well as a starting material for the manufacture of plastics and drugs. Urea is most commonly produced by reacting carbon dioxide with ammonia at high temperature. Photocatalysis has gained attention as a sustainable pathway for performing urea. This work focus on designing very active photocatalysts based on cerium organic framework (Ce-BTC) doped with metal oxide nanoparticles (molybdenum permanganate, Mo(MnO)) for production of urea from coupling of ammonia with carbon dioxide. The prepared materials were characterized using different spectral analysis and the morphology was analysed using microscopic data. The effect of catalyst loading on the production rate of urea was investigated and the obtained results showed speed rate of urea production with high production yield at low temperature. The recyclability tests confirmed the sustainability of the prepared photocatlysts (Mo(MnO)@Ce-BTC) which supported the beneficial of the photocatalysis process in urea production.
尿素用于施肥和饲料补充,也是制造塑料和药品的起始原料。尿素最常见的生产方法是在高温下使二氧化碳与氨反应。光催化作为一种可持续的尿素生产途径受到了关注。这项工作的重点是设计基于掺杂金属氧化物纳米颗粒(钼酸锰,Mo(MnO))的铈有机框架(Ce-BTC)的高活性光催化剂,用于由氨和二氧化碳偶联合成尿素。使用不同的光谱分析对制备的材料进行表征,并利用显微镜数据分析其形态。研究了催化剂负载量对尿素产率的影响,所得结果表明在低温下尿素的生成速率快且产率高。可回收性测试证实了所制备的光催化剂(Mo(MnO)@Ce-BTC)的可持续性,这支持了光催化过程在尿素生产中的益处。
