Abstract

In this paper

g-C

was prepared by calcining melamine at high temperature

and g-C

/AOCF monolithic composite catalytic material was prepared with amidoxime fiber as carrier and water bath method

which is cheap

easy to get

high catalytic activity

non-toxic

harmless and easy to recover. The samples were characterized by XRD

SEM

FT-IR

XPS

UV-Vis DRS

etc. the SEM results showed that g-C

was uniformly distributed on the surface of the fiber

showing an amorphous morphology. The XPS and FT-IR results confirmed that there was a certain chemical bond between g-C

and aocf. Under UV irradiation

the catalytic activity of the catalytic material was investigated by degradation of Rhodamine B dye. The results showed that when the addition of g-C

was 3 g/L

the reaction was carried out at 30℃ in water bath The g-C

/AOCF composite catalyst prepared by H has the best photocatalytic activity. The repeatability experiment shows that the catalyst has good stability and the photocatalytic reaction process conforms to the first-order reaction kinetics.
