It is well known that catalysts of metal ions in solution or powder metal oxides create an unstable state because the surface tension favours a smaller interfacial area for a given mass. Catalysts also cause a secondary pollutant problem that requires further treatment to remove the metal ion from water.1 Therefore, attempts have been made to improve the catalysis process by replacing the homogeneous catalysts with a heterogeneous catalyst. For this purpose, supported metal catalysts can be prepared.2 Activated carbon (AC) is one of the most widely used catalyst supports in recent years3–12 because of its high surface area, well-defined porous structure, the presence of various surface functional groups and its inertness in many catalytic processes.8
