Sulfosuccinic acid functionalized mesoporous silica (SBA/SSA) was synthesized and characterized for debenzylation of vanillic acid in liquid phase for the first time. The catalytic activity studies showed high activity (82%) and selectivity (96%) for the desired product vanillic acid over SBA/SSA compared to 74% selectivity over silica/SSA. Synergistic effects of acidic/basic groups responsible for higher activity and selectivity were explained with plausible mechanism. (C) 2014 Elsevier B.V. All rights reserved.
