Abstract:The limited specific surface area (SSA), long preparation period, and high cost are significant challenges for carbon xerogels (CXs). To overcome these limitations, we propose an approach to prepare tannin-resorcinol-formaldehyde-based CXs through template-catalyzed in situ polymerization. ZnCl 2 acts as a catalyst and significantly accelerates the polymerization reaction through the coordination of Zn 2+ to the carbonyl group in formaldehyde, while atmospheric drying instead of special drying and without solv… Show more
