FIG. 2.

(Color online) Raman spectra of pristine SiC powder (solid line) and GCSP (dotted line). The inset is Raman signal of graphene after subtracting SiC’s signal from GCSP.

FIG. 3.

(Color online) Absorption spectra of Rh B after different photo degradation durations by SiC powder (a) and GCSP (b).

Image of FIG. 4.
FIG. 4.

(Color online) The relative remnant concentration of the partly degradated Rh B versus irradiation duration. The inset is the natural logarithm of the ratio between the remnant concentration and the initial concentration of Rh B versus irradiation time.

Image of FIG. 5.
FIG. 5.

(Color online) Schematic mechanism of photocatalystic process of GCSP for degradation of Rh B.
