Correction to: Scientific Reports https://doi.org/10.1038/s41598-024-72414-y, published online 12 September 2024

The original version of this Article contained an error in the graph and its associated numerical values,

As the result of this error, in the Discussions section, under the subheading ‘Porosity percentage’,

“Considering Fig. 3, BET curve displays that the surface area of the sample covered with NB4-2 Nanoclay (double spray of 4% Nano-Bentonite solution) is equal to 18.57 square meters per gram, the volume of the holes is 0.062 cubic centimeters per gram, and the average size of the holes is equal to 13.37 nm. BJH curve also shows that most of the holes are less than 1.1 nm.”

now reads:

“Considering Fig. 3, BET curve displays that the surface area of the sample covered with NB4-2 Nanoclay (double spray of 4% Nano-Bentonite solution) is equal to 18.67 square meters per gram, the volume of the holes is 0.064 cubic centimeters per gram, and the average size of the holes is equal to 13.91 nm. BJH curve also shows that most of the holes are less than 1.85 nm.”

Consequently, Figure 3 has been corrected. The original Figure 3 and its accompanying legend appear below.
