Abstract
Mesoporous reduced graphene oxide nanoparticles (RGO NPs) have been synthesized by using different templates. Three types of RGO NPs, namely mesoporous RGO1 NPs, RGO2 NPs and RGO3 NPs, have been synthesized by using cetyltrimethylammonium bromide (CTAB), polyethylene glycol (PEG) and polyethylene glycol–polypropylene glycol–polyethylene glycol (Pluronic P123), respectively. In the present study, CTAB, PEG and P123 are used as both template and capping agent for the formation of mesoporous RGO NPs. N2 sorption, XRD, XPS and Raman spectra have proved the mesoporous and NPs nature of the RGO samples. It has been observed that mesoporous RGO NPs samples have high adsorption of dyes molecules like as methylene blue, malachite green and rhodamine 6G. Among them, mesoporous RGO1 NPs exhibited the highest dye adsorption capacity.
