Preparation of mesoporous carbon from fructose using zinc-based activators
Journal Title: Carbon - Science and Technology - Year 2015, Vol 7, Issue 3
Abstract
Mesoporous carbons were synthesized from fructose using activators of zinc silicate (ZS), zinc borate (ZB), and zinc borosilicate (ZBS). The synthesis involves 3 steps, including caramelization of sugar, carbonization of caramel, and washing of carbon to separate the activator from the carbon. The solid products were characterized by N2 gas adsorption-desorption, X-ray diffraction, FTIR spectrophotometry, and Transmission Electron Microscopy. The pore characterizations of the carbons indicate that in ZBS system, ZB may have the role as mesopore size controller, whereas silica component may improve porosity created by ZB without changing the size. This role of ZB may be connected to it’s performance as catalyst of caramelization and it’s crystalinity, as supported by measurement of caramel intermediete and characterization of the activators with X-ray diffraction. The infrared spectra confirms that the carbons’s surfaces have C=O, C-O, and O-H functional groups. The XRD patterns of the carbons show that all activators create the turbotratic carbons.
