In the original publication of the article, in the Appendix section, under the heading “Calculations by density functional theory-based methods” the ionization potential (IP) equation incorrectly appears as ${\text{IP}} = {\text{IP}} = E_{{M^{ + } }} - E_{M}$.

The correct equation is as below:

$$ {\text{IP}} = E_{{M^{ + } }} - E_{M} $$
