摘要：
The ZIF/AC materials, produced from trace amounts of zeolite imidazole skeleton ZIF-67 loaded onto commercial activated carbon (AC) particles and subsequently calcined for 6 h at a series of temperatures, exhibit highly dispersed Co and N on its surface, especially showing the same specific surface area as the original activated carbon at 800 degrees C (Co/AC-800). The adsorption desulfurization performance of Co/AC-800 for dibenzothiophene (DBT) is better than that of the two matrix materials and still the same after 5 cycles, which is mainly ascribed to the acid-base interaction, n-n interaction and further demonstrated by the quasi-second-order kinetics and Langmuir model.
