11.Catalysts And Catalyst Carriers
With its high specific surface area, adjustable pore structure and surface chemistry, activated carbon plays multiple roles in the field of catalysts and catalyst carriers. From chemical synthesis to nuclear pollution prevention and control, activated carbon has been promoting catalytic science towards high efficiency and greening by using the pores as the reactor and the surface as the active stage.
