Fabrication of mesoporous carbons coated monolith via evaporative induced self-assembly approach: effect of solvent and acid concentration on pore architecture

Carbon coating onto monolith through soft-template approach have been accomplished by means of evaporative induced self-assembly (EISA). Variation in acid and alcohol content on monolith's surface properties was studied, while β-carotene was used as a modelled adsorbate. The pore architecture o...
