In this research, sba-16 nanoprocesses were first synthesized and then the surface of this nanostructure was modified usingaminopropyltrimethoxysilane and melamine (me-asba-16). thesynthesis of sba-16 has been carried out by two surfactants f127 and p123. in addition, amino-asba-16 was used to remove 2,4-dichlorophenol from polluted water, and the effect of the initialconcentration of the pollutant and contact time on the amount of pollutantabsorption was investigated. furthermore, au-doped mesoporous carbon,au-ocmk-3, was prepared for desulfurization and denitrogenation ofrefinery fuels. the synthesis of ordered mesoporous carbon, omc, wasperformed using sba-15 silica as the hard template and sucrose as thecarbon source. the structural order and textural properties of the preparedmaterials were studied by x-ray fiffraction (xrd), scanning electronmicroscopy (sem), and n2 adsorption-desorption. au-doped oxidizedmesoporous carbon has been studied as a nanoabsorbent for removal ofdibenzothiphene from n-heptane solutions as fuel model at roomtemperature. batch adsorption studies were carried out to study the effectof contact time and initial concentration. the uptake capacity ofdibenzothiphene and carbazole followed the order: au- ocmk-3>cmk-3. the results showed that the synthesized compounds are suitablefor removing phenolic and sulfur compounds
