TBD-functionalized mesoporous silica: Synthesis and catalytic activity in corn oil transesterification

• Synthesis of TBD-functionalized mesoporous silica (MS).
• SBA-16 and KIT-6 provide viable solid supports for guanidine immobilization.
• New heterogeneous catalyst for vegetable oil transesterification.

Mesoporous silica has been functionalized with a strong organic base, 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD). The obtained high loading guanidine functionalized mesoporous SBA-16 and KIT-6 samples showed high activity in the transesterification of vegetable oil.
