总的来说就是通过部分热处理策略制备出核壳Co/MnOx@quasi-MOF-74 催化剂,这种催化剂很大程度上保留了MOF的原有骨架,并原位生成了许多高活性的Co/MnOx 纳米颗粒,提供了HAS过程中的三种协同活性位点(Co0、Co2+ &Co2C),其中Co0负责CO的解离与碳链增长,而Co2+与Co2C则负责CO的非解离吸附和插入。在 200 °C...

双金属NiMn-MOF-74催化剂,Agx-Ni-MOF-74催化剂的低温CO-SCR催化活性进一步 增强,其中Ag1-Ni-MOF-74在80℃时有超过50%的NO转化率,并在200℃达到100% 的NO转化率,引入Ag物种不仅增加了表面吸附氧和氧空位产生,而且也增加了催化 剂的比表面积,提高了对NO和CO的吸附和活化能力,进而增强了催化剂的低温CO- ...
作者以MOF为前驱体合成了Co-Nx–C催化剂,并应用于电催化固氮当中,氨产率可达37.6 μg mg−1h−1,法拉第电流效率可达到17.6%, X射线吸收精细结构光谱结合量化计算最终确定Co-N3为固氮反应最主要的活性位点。Co-N3促进了N2的吸附,降低了控速步骤的自由能,抑制了析氢反应,进而促进了N2还原。 背景介绍 在常温常...

Xu and co-workers applied a vapor phase protocol to introduce furfuryl alcohol (FA) into the nanopores of MOF-5 [74]. Consequent carbonization at 1000 °C enabled the formation of nanoporous carbon with a high specific surface area of 2872 m2 g−1. When decreasing the temperature, ...
