Correction to: Nanoscale Res Lett

In the article [1], the use of the formula (NH4)6W7O24·6H2O to represent the starting material ammonium paratungstate (APT) is outdated and incorrect.

The correct version of the formula for APT is (NH4)10[H2W12O42nH2O (n = 4, 10, 6).

The authors thank the reader who brought this to their attention after their article was published.
