.4. Catalytic performance of AgN-PW for other
esterications
In order to extend the scope of the mesoporous AgN-PW catalyst
in biodiesel production, further studies of other FFAs with
methanol were investigated (see Table S1†). When lauric acid,
myristic acid, palmitic acid, stearic acid and non-edible oils
were subjected to the esterication reaction with methanol,
high FFA conversions were obtained as well, e.g. 76.0% of
stearic acid and 90.7% of non-edible oils, superior to those of
other reports. These results show that the mesoporous AgN-
PW catalyst has great potential to catalyze many types of ester-
ication reactions to meet the demand of synthetic biodiesel.

Moreover, this catalyst could be reused and was stable for a few 17 T. M. M. Marso, C. S. Kalpage and M. Y. Udugala-
