Three mesoporous silica materials with various channel sizes and structures were employed to prepare immobilized lipase catalysts for the transesterification of unrefined wasted cooking oil (UWCO) to biodiesel at room temperature. The channel size of support material was found to be the key point to obtain high initial specific activity and high sustainability of activity of the immobilized lipase catalysts. A SBA-15 material with appropriate channel size (14.0?nm) demonstrates the best capacity of lipase. The immobilized catalyst with the SBA-15 material shows much higher activity and sustainability of activity than the immobilized catalysts with a MCM-41 material (channel size 1.8?nm) and a mesostructured cellular foam (MCF) material (channel size 28.0?nm) as support materials in the transformation of UWCO to biodiesel. After 60?h of reaction at 28?°C, a fatty acid methyl ester (FAME) yield up to 80.1 and 71.8?% of initial specific activity can be achieved using SBA-15-immobilized lipase.
