要点2.MFM-300(Cr)的禁带宽度为1.75 eV,在室温下,在H2O/CH3CN中,使用无机盐亚硫酸钠(Na2SO3)作为还原剂,在羟基修饰的MOF,MFM-300(Cr)上实现了多种醛和酮(30种底物)的有效光反应偶联,具有良好的催化活性和稳定性。 要点3....
MFM-300(Cr)-SO4(H3O)2的质子传导率呈现湿度依赖性,但它随温度的变化不大,这对于一些需要在很大温度范围内保持性能稳定的应用很有意义,比如质子交换膜燃料电池在电动车领域的应用。MFM-300(Cr)-SO4(H3O)2的质子传导性能在多次升降温、甚至保存两年后都基本保持不变,表现出了优异的稳定性,这种稳定性对实际应用极...
Synchrotron X-ray diffraction and electron paramagnetic resonance spectroscopy confirm the generation of ketyl radicals via confinement within MFM-300(Cr). This protocol removes simultaneously the need for a precious metal-based photocatalyst or for amine-based sacrificial agents for the photochemical ...
近日,英国曼彻斯特大学的杨四海/Martin Schrӧder团队报道了一系列高氨吸附量、高稳定性的MOF材料,MFM-300(VIV, Fe,VIII, Cr)。其吸附量在273 K 1 bar条件下分别可达到 17.3、16.1、15.6、14.0 mmol/g,在多轮吸附-脱附实验后,材料依旧保持了良好的结晶度,氨气吸附量也未见明显下降。文章对吸附后氨气分子与...
This work reports the thermal and electron beam stabilities of a series of isostructural metal–organic frameworks (MOFs) of type MFM-300(M) (M = Al, Ga, In, Cr). MFM-300(Cr) was most stable under the electron beam, having an unusually high critical electron fluence of 1111 e 2 ...
