Moreover, the unsaturated In atom acting as Lewis acid can also provide an active site to activate and bond with CO2 molecules. This synergetic Lewis acid–base enhancement in the activation ability towards CO2 molecules effectively promotes a continuous multi-electron hydrogenation and reduction ...
The reduced intermolecular distance causes a variation in the molecular structure, due to the intensification of mutual interactions. Some published spot data reveal the departure from the planarity of the bond angle while others provide few values of the CO2 dipole moment. Based on a small amount...

In general, the CO2reduction reaction (CO2RR) is a complex chemical process that consists of a series of electron transfer steps, hydrogenation, C–C bond coupling, and intermediate compounds. At present, products obtained from CO2RR are often classified into C1and multi-carbon C2+compounds. The...
Also, the wide-angle X-ray diffraction study confirms its semicrystalline structure. Several diffraction peaks appearing at 2y equal to 6.4°, 13.3°, 16.0°, 17.9°, 20.5° and 23.0° (d ¼ 13.80, 6.65, 5.53, 4.95, 4.33 and 3.86, respectively) are consistent with the stereocomplexed PCX...
Many parameters have been studied for SCPPs: ambient conditions [89], collector inlet opening and height, outlet diameter, chimney throat diameter, chimney divergence angle [90]. The power output of a SCPP greatly depends on chimney height and collector diameter allowing scale economies: multiplying...
Amine-functionalized adsorbents offer substantial potential for CO2 capture owing to their selectivity and diverse application scenarios. However, their effectiveness is hindered by low efficiency and unstable cyclic performance. Here we introduce an ami
As for Reaction 1–2, the HCOO intermediate (IM1-2) is generated via the formation of the C − H bond. Although the angle change of O − C − O during the transition state (TS2) is very small, it keeps decreasing during the whole hydrogenation step. As a result...
induces severe axial distortions in [Fe1]2+that are absent in [Fe(PY5Me2)(CH3CN)]2+. This distortion also significantly compresses the axial bond angle in [Fe1]2+(173.64(6)°). By comparison, the corresponding angle in the [Fe(PY5Me2)(CH3CN)]2+material is nearly linear (178.53(7...
由于C02分子中两个氧原子上富集大量电子,使得氧原子具有Lewis碱的 性质,可作为亲核中心。而C原子具有Lewis酸的性质,容易获得电子,可作为亲电子 中心llq o由此可见,C02分子的最低空闲分子轨道在获得电子后可使其产生一定的活化, 产生键长拉伸且构型弯曲的不稳定结构。 从热力学的方面看,C02分子能级较低,电子亲和能...
