This study aims to synthesis nanoporous graphene by chemical vapor deposition method on nanoporous zinc oxide. Synthesis of nanoporous graphene as a nano-adsorbent by the camphor as a carbon precursor and zinc oxide as nanocatalyst was investigated. Hydrogen gas was applied as a carrier gas, and the reaction proceeds in the temperature range from 900-1000 degrees C for 2-50 min. X-ray diffraction analysis (XRD), Fourier transforms infrared spectroscopy (FT-IR), Raman spectroscopy transmission, scanning electron microscope (SEM) and Brunauer-Emmett and Teller (BET) measurements were handled on it. BET results indicated that activated graphene has mesoporous and microporous structures and reveals type-IV isotherms. Gasoline adsorption and desorption were performed at 25 degrees C and 40 degrees C, respectively, and the results indicated that the highest adsorption capacity was 559 mg g(-1) and desorption was 212.98 mg g(-1), a specific surface area of 138.91 m(2) g(-1) and a pore volume of 0.66 cm(3) g(-1). Moreover, oxygen-containing functional groups created by activation are of the factors that contribute to increasing the adsorption capacity. The analysis results showed that the multilayer nanoporous graphene (five layers) is economically viable and promising. Furthermore, multilayer nanoporous graphene is a promising nano-adsorbent for gasoline removal based on the absorption results.
