Synthesis of Expanded Graphite : Effect of the graphite flake size on adsorption capacities to Methylene Blue

Abstract

For the first time, the expansion grade of graphite was studied through the effect of the flake size. The result shown the larger flake size exhibits a higher expansion grade. In addition, the more expanded material, the higher specific surface area can be obtained. The synthesized expanded graphites were used for the adsorption of methylene blue. The expanded graphite with the highest expansion grade displayed the highest adsorption capacity due to its specific surface area.

Highly active hydrogenation of 4-methoxyacetophenone by the novel carbon-supported ternary nanocatalyst palladium-vanadium-cobalt

“…Thus, there have been many reports on hydrogenation reactions using metallic catalysts gaining high activity, good selectivity, long-term stability, and facile recovery. Among them, nickel [9][10][11] and palladium [5][6][7][8] are two bright catalysts for hydrogenation. In recent years, the multimetallic catalysts [12] have been interested in various application such as hydrogen evolution [13,14], oxygen reduction [15,16], alcohol oxidation [12,17] and hydrogenation [18][19][20][21] as well.…”
