After carefully recovering the solid sample from the reactor
vessel and stirring shafts by rinsing with deionized water the collected
solution was centrifuged. The solid material was retained
and placed in an oven at 110 ◦C to dry overnight. The solid was then
stored in a desiccator to cool down to room temperature before
weighing. The mass of the catalyst was subtracted from the solid
mass to obtain CM (f) and the conversion calculated using Eq.
