Abstract
The invention discloses a preparation method of cobalt-loaded mesoporous graphite-phase carbon nitride (Co/mpg-C3N4) and an application of cobalt-loaded mesoporous graphite-phase carbon nitride (Co/mpg-C3N4) in visible-light-induced catalytic degradation of methylene blue. The catalyst is prepared by steeping a cobalt precursor and roasting at high temperature. The preparation method comprises the following steps of: (1) roasting at high temperature by using silica solution (Ludox, HS-40, 12nm, 40wt%SiO2) as a template and cyanamide as a carbon source and a nitrogen source, and removing the template to prepare mesoporous graphite-phase carbon nitride (mpg-C3N4); and (2) steeping the precursor solution of cobalt into mpg-C3N4, carrying out secondary high-temperature roasting in a muffle furnace to prepare the load-type catalyst Co/mpg-C3N4. By using the cobalt-carried mesoporous graphite-phase carbon nitride as the visible-light-induced catalyst, the result shows that the effect of the cobalt-carried mesoporous graphite-phase carbon nitride used for the visible-light-induced catalytic degradation of methylene blue is good, and the visible-light-induced catalytic degradation rate is obviously improved in comparison with the mesoporous graphite-phase carbon nitride (mpg-C3N4) without cobalt.
