EFFECT OF CARBON SURFACE CHEMISTRY ON THE Cu~(3+) + BENZENE-1,3,5-TRICARBOXYLIC ACID REACTION

摘要

Porous carbon materials are often used as catalyst supports. Their high surface area offers the possibility of obtaining finely and uniformly dispersed high performance metal or metal oxide catalysts. The textural and chemical characteristics of carbon aerogels (CAs) that are simultaneously micro-, meso- and macroporous predispose them as thermal and phonic insulators, electric double layer and super capacitors, chromatography packing, adsorbents, catalyst support, etc. For more than two decades sol-gel techniques have been applied to prepare polymer aerogels with tailored structure, which are excellent precursors for porous carbon [1, 2]. Carbon gels can be prepared from resorcinol (R) and formaldehyde (F) under controlled conditions (solvent, concentration, stoichiometry, choice of catalyst in the precursor solution, pH, etc.). Most of these parameters act by influencing the mechanism and kinetics of the polycondensation process. The tailored structure of the resorcinol-formaldehyde (RF) hydrogels can be preserved by careful removal of the solvent [3].
