Oxygen has many uses because of its ability to accept electrons from other elements to formionic bonds or to share electrons with other elements to form covalent bonds. View all Uses The most obvious use of oxygen is to support life. The process of aerobic respiration uses O2 in an ...
In this process electrons trapped by oxygen ions are released to the semiconductor, thereby increasing the electron concentrations in n-type semiconductors (Eq. (2)) [76,87]. Since the concentration of CO2 reacting with oxygen ions on the surface has a proportionable effect on the conductivity ...
Thed-band model has been widely adopted to understand bond formation and trends in reactivity among the TMs and their alloys. The facet, alloying, defects, strain and so forth greatly impact thedstates and thus alter the reactivity [44,45]. In context of the OER, the free-energy descriptor...
However, greater the concentration of PTFE in electrode substrate (e.g. carbon paper/cloth), lower will be its electrical conductivity as PTFE will hinder the flow of electrons from catalyst layer to the diffusion layer. Therefore, 15 wt% of PTFE has been chosen to be optimized value for ...
The structural, electronic, and optical properties of β-Ga2O3 with oxygen vacancies are studied by employing first-principles calculations based on density function theory. Based on the defects formation energies, we conclude the oxygen vacancies are mo
