An amorphous SiO 2 –ZrO 2 catalyst shows high activity in the esterification of free fatty acids contained in vegetable oils while at the same time promoting the transesterification of triglycerides. The catalyst is hence a good candidate for a low‐waste deacidification pretreatment or for a one‐pot biodiesel production process starting from oils with a high acid content.
