This research focused on the removal of dibenzothiophene (DBT) from model diesel oil using CuO-loaded γ-Al2O3–reduced graphene oxide (CuO/γ-Al2O3–RGO) as an adsorbent, which possesses the highest adsorption capacity among reported regenerable graphene-related materials. The boehmite–RGO supports were synthesized using a one-pot hydrothermal synthesis method. As the RGO sheet surfaces are completely covered and isolated by boehmite nanorods formed via hydroxyl condensation of [Al(OH)x](3–x)+ or Al(OH)3 and the −OH of graphene oxide (GO), the specific surface area of boehmite–RGO increased to 378 m2/g, which is 20.8% higher than that of RGO (313 m2/g). CuO/γ-Al2O3–RGO adsorbents with different CuO contents were prepared, and their DBT adsorption desulfurization properties were evaluated. With a 2% mass ratio of CuO to boehmite–RGO, CuO/γ-Al2O3–RGO displays the highest DBT adsorption capacity (6.0 mg S/g) under ambient conditions, which improved by 53.8% in comparison with that of pure RGO (3.9 mg S/g). Moreover, the regeneration of the CuO/γ-Al2O3–RGO adsorbent is much more practical than that of the pure RGO adsorbent.

再生的CuO /γ-Al系2 ö 3 -减少石墨烯氧化物吸附材料与从模型柴油一个较高的吸附能力为二苯并噻吩

该研究集中于从模型柴油用CuO-负载在γ-Al中除去二苯并噻吩的噻吩(DBT)2 ö 3 -减少石墨烯氧化物(氧化铜/γ-Al系2 ö 3 -RGO)作为吸附剂,其具有最高的吸附报告的可再生石墨烯相关材料的容量。勃姆石-RGO载体是使用一锅法水热合成方法合成的。由于RGO板的表面完全被勃姆石纳米棒覆盖和隔离,勃姆石纳米棒是通过[Al(OH)x ] (3- x)+或Al(OH)3和氧化石墨烯(GO)的-OH的羟基缩合形成的勃姆石纳米棒勃姆石-RGO的表面积增加到378 m 2/ g,比RGO(313 m 2 / g)高20.8%。的CuO /γ-Al系2 ö 3 -RGO吸附剂具有不同的CuO含量,制备,和它们的DBT脱硫的吸附性能进行了评价。用的CuO到勃姆石-RGO,CuO的/γ-Al系2%的质量比2个ö 3 -RGO显示最高DBT吸附容量(6.0毫克S /克)的环境条件,这在比较与改善了53.8%下纯RGO(3.9 mg S / g)。此外,的CuO /γ-Al的再生2 ö 3 -RGO吸附剂比纯RGO吸附剂的更加实用。
