The original article requires minor corrections.

In synthesis section (page No. 2888) the calcination temperature has been inadvertently mentioned as “450 °C for 1 h”, but it should be read as “300 °C for 1 h”.

In Table 1 (page No. 2889) the unit for Raman modes not mentioned and the unit is “cm− 1”.

The discussions and conclusion are not altered by this correction.

The authors regret for the oversight.
