过氧化尿素(CO(NH2)2•H2O2)作为尿素的衍生物,已广泛应用于制药、农业、纺纱、日常化工等。CO(NH2)2•H2O2的工业生产主要依赖于尿素和H2O2这两种反应物。其中,通过碳源(CO2)和氮源(N2、NO、NO2−、NO3−)耦合高效电催化剂,可以在电化学条件下通过电催化C-N偶联反应有效地生成尿素。同时,利用高效电催化剂和活性OOH中间体的适当 ...
在质子交换膜燃料电池(PEMFC)中,Pt是氧还原反应(ORR)活性最高的材料。然而,贵金属Pt储量稀少和价格昂贵,减少材料中Pt含量是减少其使用的最直接的策略,但这通常伴随着活性位点数量的减少或发生团聚。Pt与其他后过渡金属合金化提高了Pt的活性, ...

当人类还在为碳捕集的能耗难题焦头烂额时,中国科学家已经跳过了“先捕集再转化”的传统流程——直接从空气中“抓”出二氧化碳,让它在阳光下变成能溶于水的尿素。这不是实验室里的偶然数据,而是能在开放空气里稳定运行的“碳转化生产线”:利用卟啉铟金属-有机框架(In-MOF)的“空间分区”智慧,让氧气从抑制剂变成助推器;通过异质结的“双重富集”效应,让浓度仅420ppm的大气CO2主动“聚集”到催化位点;最终 ...
