Abstract

Correction for ‘Mesoporous Ag1(NH4)2PW12O40 heteropolyacids as effective catalysts for the esterification of oleic acid to biodiesel’ by Qiu-yun Zhang et al., RSC Adv., 2017, 7, 51090–51095.


Fig. 4 in the published article was incorrect as the adsorption/desorption isotherms were not shown. A correct version of the figure is shown below:
