The adsorption of CO, H2S and CH4 on the intrinsic SnS2 monolayer and SnS2 monolayer with S-vacancy were studied by the first principle method. The most stable adsorption geometry was determined, and the electronic structure and differential charge were calculated. The results show that the band...
The morphology and thickness of the membranes were investigated using a scanning electron microscope (SEM, FEI Magellan 400 field emission XHR-SEM) operated at an accelerating voltage of 3 kV and a probe current of 6.3 pA. No conductive coating was applied to the samples. The membranes were mo...

To determine whether the statement about the difference in properties of CH₄ (methane) and SiH₄ (silane) being due to the large difference in electronegativity of carbon and silicon is true or false, we can follow these steps:1. I
and productivity is a prerequisite. Copper (Cu) has been extensively noted for their high catalytic activity towards hydrocarbons for CO2RR26,27,28,29. However, selective production of CH4using Cu catalysts can be difficult owing to the sluggish eight electron transfer steps of CO2-to-CH4and ...

be concluded that there is one electron associated with the [F2] unit on the surface; therefore, we label it as an [F2]−unit. The Ni–F distances in the bulk region are 2.014 Å and 2.015 Å, whereas both the surface Ni–F distances are significantly shorter at 1.881 Å. The...
The elemental identification and quantitative compositions of the activated carbon samples were analyzed using a scanning electron microscope with energy dispersive X-ray (SEM-EDX) instrument (JSM-7800F, JEOL). 4. Conclusions In the experimental part, the adsorption capacities of carbon dioxide on ...
What is the molecular geometry of Cl2O using the VSEPR theory? Explain how you use the VSEPR theory to predict polarity. Your answer should include a discussion of the connection between electron geometry, molecular geometry, and symmetry. Walk through the process of using the two geometries an...
