The authors noticed that the E-factor (E) was calculated using a wrong Equation 2 in the original publication:
The correct Equation 2 should be the following:
Accordingly, the Conclusion section should be amended with the following sentence:
A high AE of 74% and a low E-factor of 0.43 highlight the green character of the procedure.
The authors apologize for any inconvenience caused by the originally published wrong Equation 2.
