A molecule is a group of two or more atoms joined by chemical bonds, whereas a compound is a substance formed by the chemical bonding of more than one type of element that exists in a fixed proportion.
The H2-CO2 fuel cell is a promising CCU technology that utilizes CO2 as a resource to generate electricity while producing a valuable compound (CH4). However, the CH4 yield as well as the amount of power generated need to be increased to further develop this technology, and the efficient ...
For the low-spin case, the VBM is composed of Fe 3d orbitals and the CBM is composed of N 2p orbitals. The reduction in band gap from low to high spin state can be rationalized on the basis of crystal field theory. In the high spin state, the Fe(II) centers have a t2g4eg2 ...
